One of America's most celebrated national parks, Yosemite spans nearly 1,200 square miles (3,100 km) of California's Sierra Nevada — a landscape of sheer granite walls, ancient sequoia groves, thundering waterfalls, and high alpine meadows carved by glaciers over millions of years. This guide covers everything a first-time visitor needs: the seven must-see attractions, six recommended hiking trails, a practical 3-day itinerary, seasonal guidance, permit requirements, safety guidelines, and current lodging and ticketing information.

Park Overview

Best Time to Visit

Spring (April  May)

• Peak waterfall season — Yosemite Falls, Bridalveil Fall, and Vernal Fall run at full volume as snowmelt feeds the valley
• Wildflowers carpet Yosemite Valley meadows; black bears emerge from hibernation
• Tioga Road (the high-country highway) typically remains closed until late May or June, depending on snowpack
• Timed-entry reservation required during peak season — Yosemite has reinstated its "Peak Hours Plus" reservation system, typically covering mid-April through mid-October on weekends and all days during the height of summer; reservations must be secured in advance at recreation.gov; visitors without a reservation may be turned away at the gate after 5:00 AM; guests staying at in-park lodges or campgrounds are exempt

Summer (June  August) — Most Popular

• All roads and facilities open; long daylight hours ideal for high-mileage days
• Half Dome cables installed — typically late May through Columbus Day weekend
• Valley temperatures of 85 95°F (29 35°C); Tuolumne Meadows significantly cooler at 8,600 feet (2,621 m)
• Book lodging 12 months in advance; most Valley properties sell out on their first available date

Fall (September  October)

• Crowds thin after Labor Day; ideal temperatures for hiking
• Tioga Road typically closes in November; visit before then for high-country access
• Waterfalls run lower after the dry summer season
• Best season for photography — golden light, uncrowded meadows, and early-season color on the valley walls

Winter (November  March)

• Yosemite Valley remains open year-round; Tioga Road and Glacier Point Road close
• Snow on the granite walls creates a wholly different visual character
• Far fewer visitors; lodging available without booking a year in advance
• Half Dome cables taken down for the season (poles and planks removed; cables lowered flat against the rock face); chain controls may apply on Valley roads

Top Attractions

1. Yosemite Valley — The Central Stage

The glacially carved valley at the heart of the park — roughly 7 miles (11 km) long, 1 mile (1.6 km) wide, and flanked by granite walls rising 3,000 4,000 feet (900 1,220 m) — delivers the iconic views that define Yosemite. El Capitan, the world's largest granite monolith at 3,593 feet (1,095 m) above the valley floor, dominates the western end. Half Dome, rising 4,737 feet (1,444 m) above the valley floor, anchors the east. The Valley Loop Trail — 13 miles (21 km) of paved and compacted paths — connects all major viewpoints, meadows, and trailheads, making the valley fully explorable on foot or by free shuttle.

2. Yosemite Falls

At 2,425 feet (739 m) total, Yosemite Falls is the tallest waterfall in North America and the fifth tallest in the world. It falls in three separate drops — the Upper Fall (1,430 ft / 436 m), the Middle Cascades, and the Lower Fall (320 ft / 98 m) — visible from throughout the valley. The trail to the base of Lower Yosemite Fall is a flat 1-mile (1.6 km) round-trip walk from the Valley shuttle. For the full experience, the Upper Yosemite Fall Trail (7.2 mi / 11.6 km RT, strenuous) climbs to the canyon rim for a top-down perspective. Peak flow runs March through May; the falls can run dry by August in dry years.

3. Half Dome

The park's most iconic feature and the goal of its most coveted hike. The 14.2-mile (22.9 km) round-trip via the Mist Trail ascends 4,800 feet (1,463 m) from Yosemite Valley, passing Vernal Fall and Nevada Fall before the final steel-cable ascent of Half Dome's curved granite face. A permit is required to ascend the cables — issued by daily and preseason lottery through Recreation.gov. Without a permit, the Subdome viewpoint at the base of the cables is still an extraordinary destination at approximately 12 miles (19.3 km) RT. The cables are up from approximately late May through Columbus Day weekend.

Permit logistics: The preseason lottery opens in March for the following summer. Daily lotteries open two days before the hike date. Apply at recreation.gov. The permit fee is $10 per application plus $10 per person if selected.

4. Glacier Point

A 3,214-foot (980 m) drop from the valley floor and one of the most accessible panoramic viewpoints in any national park. From the paved overlook, Half Dome stands at eye level to the east; Yosemite Falls spills down the northern wall; Nevada Fall and Vernal Fall gleam silver to the southeast. Glacier Point Road is open approximately May through November; a free park shuttle connects the valley to Glacier Point during the summer season, making the view accessible without hiking. For those who prefer to earn it, the Four-Mile Trail climbs 3,200 feet (975 m) in 4.8 miles (7.7 km) one way.

5. Mist Trail — Vernal Fall & Nevada Fall

Yosemite's most popular and dramatic inner-valley hike. The trail climbs granite steps beside the Merced River to the top of Vernal Fall (317 ft / 97 m) at 3 miles (4.8 km) RT, then continues to Nevada Fall (594 ft / 181 m) at 6.4 miles (10.3 km) RT. In spring, the trail runs through continuous spray from the waterfalls — carry a rain jacket and expect to get thoroughly wet. The ascent is steep and the granite steps can be slippery; trekking poles strongly recommended. This trail also serves as the access route for Half Dome.

6. Mariposa Grove — Giant Sequoias

The park's largest grove of giant sequoias, located near the South Entrance. The Grizzly Giant — at roughly 2,700 years old and 209 feet (64 m) tall, one of the oldest living trees on Earth — stands 0.8 miles (1.3 km) from the grove trailhead. The California Tunnel Tree, a sequoia bored through in 1895, is nearby. A free shuttle from the South Entrance parking area connects to the grove in summer; the road opens to vehicles when the shuttle is not running. Allow 1.5 2 hours for a relaxed exploration of the lower grove.

7. Tuolumne Meadows

At 8,600 feet (2,621 m), Tuolumne Meadows is the largest subalpine meadow in the Sierra Nevada — a vast, open expanse of green grass, granite domes, and the crystal-clear Tuolumne River accessible via Tioga Road (Highway 120). Open from approximately late May to November, it offers a completely different character from the crowded valley floor: cooler temperatures, thinner crowds, outstanding day hiking, and access to the John Muir Trail. The Cathedral Lakes Trail (7 mi / 11.3 km RT, moderate) to two turquoise alpine lakes is one of the park's finest day hikes.

Hiking Trails

Getting Around

Yosemite Valley operates a free shuttle system with multiple stops serving all major trailheads, lodges, and viewpoints. The shuttle runs year-round in Yosemite Valley (summer hours: 7:00 AM  10:00 PM) and seasonally to Glacier Point and Tuolumne Meadows. No tickets are required; service is included with park entry.

Timed-entry reservations: Yosemite operates a "Peak Hours Plus" reservation system during peak season — typically mid-April through mid-October on weekends, and daily during the height of summer. Reservations must be secured in advance at recreation.gov; visitors arriving without one after 5:00 AM during reservation-required periods may be turned away at the entrance gate. Guests with confirmed lodging or camping reservations inside the park are exempt. Always verify the current year's reservation requirements at nps.gov/yose before booking travel, as the exact dates and rules are adjusted annually. Outside peak-season windows, no reservation is needed. Valley parking fills before 9:00 AM on summer mornings regardless — arriving before dawn or using the YARTS bus from surrounding towns is strongly advisable.

YARTS (Yosemite Area Regional Transportation System): Seasonal bus service connects Yosemite Valley with Merced, Mammoth Lakes, Fresno, and Sonora. Buses run during the summer season and bypass the parking problem entirely. Fare is approximately $15 $30 one way depending on origin; included with park entry.

On the road: The Big Oak Flat Road (Highway 120) from the west and Highway 41 from the south are the most common approaches. Highway 120 East over Tioga Pass (closes in winter) is the most scenic approach from the east. The park speed limit is strictly enforced; watch for wildlife at dawn and dusk in valley meadows.

Suggested 3-Day Itinerary

Day 1 · Yosemite Valley — Foundations

• 7:00 AM: Arrive at Valley Visitor Center and collect a map. Walk directly to Valley View near the western end of the valley — the classic first-glimpse framing of El Capitan and Bridalveil Fall.
• 8:30 AM: Follow Southside Drive eastward (the valley's one-way road) toward El Capitan Meadow. Park at the Bridalveil Fall lot or use the shuttle — do not attempt to drive westward back toward Valley View, as Northside and Southside Drives run in fixed one-way directions. Walk the El Capitan Meadow section for unobstructed views of the vertical granite face from below.
• 10:00 AM: Board the free shuttle to Yosemite Falls trailhead. Walk the 1-mile (1.6 km) round-trip to the base of Lower Yosemite Fall. If fit and time allows, continue up the Upper Yosemite Fall Trail for 2 3 hours (partial ascent).
• 1:00 PM: Lunch at Yosemite Village (Degnan's Kitchen or the Village Store).
• 2:30 PM: Shuttle to Happy Isles and walk the Mist Trail to the top of Vernal Fall (3 mi / 4.8 km RT). Allow 2 2.5 hours. Carry a rain jacket — the spray is real.
• Evening: Check in to in-valley lodging. Walk to Sentinel Bridge at dusk — the reflection of Half Dome in the Merced River is the park's most photographed image.

Route logic: Valley View (west entry, Northside Drive) → El Capitan Meadow (Southside Drive eastbound) → Yosemite Falls shuttle stop (north valley) → Happy Isles (east end). Follows the valley's one-way road system eastward on Southside Drive; shuttle handles north-valley stops. No backtracking.

Day 2 · Glacier Point & High Views

• 7:00 AM: Depart for Glacier Point via Glacier Point Road (open May November). Arrive before 9:00 AM to beat crowds and catch the morning light on Half Dome.
• 9:00 AM: Spend 1 hour at Glacier Point overlooks. Walk the short trail to Washburn Point, 0.5 miles (0.8 km) south, for Nevada Fall views.
• 10:30 AM: Drive north to Tuolumne Meadows via the valley and Tioga Road (if open). Stop at Olmsted Point — a roadside overlook with a sweeping view of Half Dome's back face — and Tenaya Lake.
• 1:00 PM: Picnic lunch in Tuolumne Meadows. Begin the Cathedral Lakes Trail (7 mi / 11.3 km RT, moderate) or the shorter Lembert Dome walk (2.8 mi / 4.5 km RT) for high-country perspectives unavailable from the valley.
• Evening: Return to Valley lodging via Tioga Road and the Big Oak Flat Road.

Route logic: Valley → Glacier Point (south rim) → Tuolumne Meadows (northeast via Tioga Road). Single-direction arc across the park's high country; Tioga Road return closes the loop without repeating roads.

Day 3 · Mariposa Grove & Departure

• 7:30 AM: Drive south to Mariposa Grove. Take the free shuttle from the South Entrance parking area (summer) or drive in if the shuttle is not running.
• 8:00 AM: Walk to the Grizzly Giant (1.6 mi / 2.6 km RT) and continue to the California Tunnel Tree (2.4 mi / 3.9 km RT). Allow 2 hours.
• 10:30 AM: Drive north through the valley for a final look. Stop at Valley View (the same viewpoint from Day 1) — the afternoon light now strikes El Capitan from the opposite angle.
• Midday: Depart via Highway 41 south to Fresno or Highway 120 west to Merced, depending on onward destination.

Route logic: Valley lodging → Mariposa Grove (south entrance area) → Valley (northward pass-through) → South or West exit. Southward morning; northward return to exit. No roads repeated.

Accommodations

Inside the Park (book via travelyosemite.com or call 888-413-8869; rooms open 12 months in advance)

Gateway Towns Outside the Park

• El Portal, CA — 2 miles (3.2 km) from the Arch Rock Entrance; closest lodging outside the valley; Yosemite View Lodge and Cedar Lodge are the main options
• Mariposa, CA — 45 miles (72 km) southwest on Highway 140; charming Gold Rush-era town; most diverse lodging selection outside the park
• Groveland, CA — 22 miles (35 km) from the Big Oak Flat Entrance on Highway 120; historic town with inns and B&Bs; popular with repeat visitors

Packing Essentials

• Bear spray is strictly prohibited inside Yosemite National Park — unlike Yellowstone or other parks, Yosemite classifies bear spray as a harmful weapon under federal law; carrying, using, or purchasing it within the park is illegal and subject to confiscation and significant fines; the park contains only black bears, which respond best to loud noise and assertive behavior — not spray
• Bear canister or bear box awareness — all food must be stored in bear boxes provided at campgrounds and parking areas; do not leave any food, toiletries, or scented items in your vehicle
• Rain jacket — required on the Mist Trail; also useful for afternoon valley thunderstorms May through August
• Trekking poles — strongly recommended for Half Dome and Nevada Fall; the granite steps on the Mist Trail are steep and uneven when wet
• Sunscreen and a sun hat — UV exposure intensifies above 6,000 feet; granite reflects additional radiation
• Layered clothing — valley temperatures vary 30°F (17°C) between dawn and midday; Tuolumne Meadows is consistently 15 20°F (8 11°C) cooler than the valley
• 1.5 2 liters of water per person — water is available at valley trailheads but scarce on upper trails in summer; carry enough for the round trip
• Cash — some food and shuttle services within the park are cash-preferred
• Offline maps — cell service is extremely limited in the valley and nonexistent in the high country; download Yosemite maps to your device before arrival

Safety Guidelines

1. Wildlife — black bears are active throughout Yosemite. Bear spray is illegal in the park. Yosemite is home to black bears only — there are no grizzly bears in the Sierra Nevada. Unlike Yellowstone and Grand Teton, Yosemite National Park prohibits bear spray entirely — it is classified as a harmful weapon under federal law; carrying it is grounds for confiscation and a significant fine. If you encounter a black bear on a trail: stand tall, wave your arms, shout loudly, make yourself appear large, and give the bear room to move away. Never run — it can trigger a chase response. Back away slowly once the bear disengages. All food must be stored in park-provided bear boxes at campgrounds and parking areas; leaving food in vehicles carries heavy fines and is a leading cause of property damage in the valley.
2. Wildlife distances — enforced by rangers:
   • Bears, deer, coyotes, and all wildlife: 25 yards (23 m) minimum at all times
   • Do not feed any wildlife under any circumstances — it is a federal offense
3. Waterfall hazard: Slippery rocks above waterfalls are responsible for multiple fatalities annually. Stay behind railings; never step to the edge of Vernal or Nevada Falls.
4. Half Dome cable ascent: The final 400 feet (122 m) of the Half Dome route involve fixed steel cables on a 45-degree granite slope. Gloves are mandatory — the cables strip skin from bare hands. Descent is as dangerous as ascent. Turn back if a thunderstorm approaches — lightning strikes Half Dome regularly.
5. Altitude acclimatization: Tuolumne Meadows sits at 8,600 feet (2,621 m). Visitors arriving from sea level should spend at least one night at valley elevation (4,000 ft / 1,219 m) before undertaking high-country hikes. Headache, nausea, and shortness of breath are signs to descend.
6. Sun and heat: Valley temperatures can exceed 95°F (35°C) in July and August. Start all strenuous hikes before 8:00 AM; carry significantly more water than you think you need.

Practical Information

Photography Golden Hours

• Dawn at Sentinel Bridge: The reflection of Half Dome in the Merced River is the park's most reproduced image — arrive 20 minutes before sunrise for the stillest water and most saturated colors; the slightest breeze destroys the reflection
• Morning on El Capitan Meadow: The west-facing granite wall catches direct light from 7:00 10:00 AM; binoculars allow you to spot climbers on the face against the lit rock
• Spring mist on the Mist Trail: High water volume in April and May fills the air with spray that catches the mid-morning light in miniature rainbows; a wide-angle lens is more useful than a telephoto here
• Tunnel View at any hour: The classic valley entrance overlook frames El Capitan, Bridalveil Fall, and Half Dome in a single composition; early morning offers mist in the valley; late afternoon delivers warm side-light on the walls
• Winter — the rarest shot: A fresh snowfall coating the valley meadows and cliff bases while the waterfalls still run creates conditions impossible in any other season; December through February offer the park's least-visited and most dramatically lit mornings

*Take nothing but photographs. Leave nothing but footprints. Remember nothing but the wonder.
