Overview
Yosemite National Park occupies roughly 750,000 acres of the central Sierra Nevada in California. Established in 1890, it is one of the oldest national parks in the United States and a UNESCO World Heritage Site. The park is best known for Yosemite Valley — a seven-mile glacially carved canyon flanked by El Capitan, Half Dome, and Bridalveil Fall — but the wider park encompasses alpine meadows, ancient sequoia groves, and high-country wilderness stretching above 13,000 feet.
Yosemite receives several million visitors each year, making advance planning essential. The park is divided into distinct regions: Yosemite Valley, Wawona and the Mariposa Grove in the south, Tuolumne Meadows along the high-elevation Tioga Road, and the Hetch Hetchy reservoir area in the northwest. Each zone has a markedly different character and pace.
The park sits within a broader ecosystem that includes the Stanislaus and Sierra national forests. Visitors looking for wilderness backcountry, technical climbing, or long-distance trails such as the John Muir Trail will find Yosemite a serious destination, not merely a scenic drive.
Before You Go
Reservations and Entry Permits
Yosemite requires a timed-entry reservation during peak season (typically late spring through early fall on weekends and holidays). Check the official National Park Service website (nps.gov/yose) well in advance, as reservations open months ahead and sell out quickly. An America the Beautiful annual pass covers the entrance fee for multiple federal lands and is worth considering if you plan to visit other parks during the year. Verify current fee amounts and reservation windows on the official site before your trip.
Campground Bookings
Most campgrounds inside the park are reservable through recreation.gov and often fill within minutes of becoming available. A small number of sites are held for first-come, first-served occupancy. If camping is central to your plans, treat the reservation date like a ticketed event and be ready at the booking window open time.
What to Pack
- Layered clothing: valley temperatures and high-country temperatures can differ by 30°F or more on the same day
- Sun protection — UV exposure is intense at elevation
- Bear canister if backpacking (required in most wilderness zones)
- Navigation: cell service is unreliable across much of the park; download offline maps or carry a paper map
- Reusable water bottles — potable water is available at valley facilities but scarce in the backcountry
Seasonal Considerations
Tioga Road (Highway 120 through the high country) is typically closed from November through late May or early June, depending on snowpack. Mariposa Grove may also have seasonal access restrictions. Check road conditions on the NPS site before traveling.
Getting There
By Air
The closest major airports are Fresno Yosemite International (FAT), approximately 65 miles south, and San Francisco International (SFO) and Oakland International (OAK), roughly 170 miles west. Renting a car from any of these airports gives the most flexibility. Mammoth Yosemite Airport to the east serves limited regional routes and is a viable option for visitors approaching via Highway 395.
By Car
The park has four vehicle entrances. The most commonly used are the Arch Rock entrance on Highway 140 from Merced (open year-round), the Big Oak Flat entrance on Highway 120 from the Bay Area (open year-round), and the South entrance on Highway 41 from Fresno (open year-round). The Tioga Pass entrance on Highway 120 East is seasonal. Note that Highway 140 along the Merced River canyon is generally considered the most scenic lower-elevation approach.
Parking inside Yosemite Valley is limited and congested during peak months. The park strongly encourages using shuttle systems once you arrive. Check current parking availability alerts on the NPS app.
By Bus and Train
Amtrak's San Joaquin service connects the Bay Area and Los Angeles to Merced, where YARTS (Yosemite Area Regional Transportation System) buses connect to the valley floor. YARTS also operates routes from Fresno, Mammoth Lakes, and other gateway towns. Verify current schedules and fares directly with YARTS, as service levels vary by season.
Getting Around
Free Valley Shuttle
The park operates a free shuttle bus system that loops through Yosemite Valley, stopping at trailheads, lodges, campgrounds, and visitor facilities. During peak season this is the most practical way to move around the valley without dealing with parking. Shuttles run frequently during daylight hours; confirm current operating hours on the NPS site.
Hiking and Cycling
More than 800 miles of maintained trails range from paved, accessible valley paths to strenuous multi-day wilderness routes. A network of paved bicycle paths runs through the valley floor; bicycle rentals are available seasonally at designated locations within the park — verify current providers and rates locally. Cyclists must yield to pedestrians and follow posted regulations.
Driving in the Park
For areas outside the valley — Tuolumne Meadows, Wawona, Hetch Hetchy — a personal vehicle or rental car is generally necessary. Roads can be narrow and winding; oversized vehicles face restrictions on some routes. Check the park's vehicle size guidelines before bringing RVs or trailers.
Where to Stay
In-Park Lodging
Aramark's Yosemite Hospitality (operating as Yosemite Hospitality, LLC) manages all lodging within the park under a concession agreement. Options range from The Ahwahnee — a historic grand lodge in the valley — to more modest cabins and tent cabins at properties such as Curry Village (Half Dome Village) and Housekeeping Camp. Glamping-style tent cabins are popular with families. In-park accommodation books up many months in advance; reservations open approximately 366 days ahead. Verify current booking windows, rates, and availability at the official Yosemite lodging site.
Gateway Towns
El Portal, Mariposa, Groveland, and Lee Vining (for eastern Sierra access) all offer motels, vacation rentals, and B&Bs at varying price points. Staying in a gateway town and driving or taking YARTS into the park is a practical and often more affordable strategy during high season. Fish Camp and Oakhurst on the south approach also have accommodation options close to the Highway 41 entrance.
Camping
Campgrounds within the park include Yosemite Valley campgrounds (Upper Pines, Lower Pines, North Pines), Wawona, Crane Flat, Hodgdon Meadow, and the high-country sites at Tuolumne Meadows. Backcountry camping requires a wilderness permit, issued through a quota system. Check recreation.gov and the NPS wilderness permit page for current procedures.
Things to See & Do
Iconic Valley Landmarks
- Half Dome: The park's most recognized feature. The Half Dome cables route is a strenuous day hike requiring a separate permit during the permit season; verify application windows on the NPS site well ahead of your trip.
- El Capitan: A 3,000-foot granite monolith attracting rock climbers from around the world. The El Capitan Meadow area is a good spot for watching climbers through binoculars.
- Yosemite Falls: One of the tallest waterfalls in North America. Flow peaks in May and early June. A relatively accessible paved path leads to the base; a strenuous trail reaches the top.
- Bridalveil Fall: Near the valley entrance; a short, mostly paved walk from the parking area.
- Mirror Lake / Mirror Meadow: A short valley walk or bike ride to a reflective seasonal lake, most photogenic in spring.
High Country
Tuolumne Meadows, accessible via Tioga Road, offers a completely different landscape of open subalpine meadows, granite domes, and high-altitude trails. Cathedral Lakes, Lembert Dome, and Soda Springs are popular day destinations.
Mariposa Grove
The park's largest sequoia grove, containing over 500 mature giant sequoias including the Grizzly Giant. A shuttle from Yosemite Valley or the Wawona Visitor Center makes the grove accessible without adding to local parking pressure.
Wildlife Watching
Black bears, mule deer, Steller's jays, and peregrine falcons are among the species regularly observed. Keep a minimum distance from all wildlife and never feed animals — it is both illegal and harmful to them.
Climbing
Yosemite is a globally significant climbing destination. The Yosemite Decimal System (YDS) of route rating was developed here. Beginner to advanced routes exist throughout the park; the Yosemite Mountaineering School offers instruction for those new to the sport.
Food & Drink
Dining Options
The Ahwahnee Dining Room is the park's most formal restaurant, serving breakfast, lunch, and dinner in a historic Great Hall setting; reservations are strongly advised and can be made through the Yosemite lodging system. More casual options in the valley include the Village Grill, Degnan's Kitchen, and the Pizza Patio (seasonal). Curry Village (Half Dome Village) has multiple quick-service outlets. Hours and seasonal availability shift — confirm current options on the Yosemite Hospitality website.
Self-Catering
The Yosemite Valley Lodge and Village areas have small grocery and convenience stores carrying basic provisions, camping food, and snacks. Prices reflect the remote concession setting. For a full grocery run, gateway towns such as Mariposa or Groveland have better-stocked supermarkets at more typical prices.
Bear-Safe Food Storage
Food storage regulations are strictly enforced throughout the park. In frontcountry areas use bear boxes provided at campgrounds and parking areas. In the backcountry, an approved bear canister is required in most zones. Leaving food or scented items unattended or in vehicles can result in fines and damages wildlife.
Practical Information
Cell Service and Connectivity
Mobile coverage is very limited inside the park. Most carriers have signal in portions of Yosemite Valley near the visitor center, but coverage drops off quickly on trails and disappears entirely in the high country. Download maps, permits, and any needed information before entering the park. Wi-Fi is available at some lodge locations — verify with the concession operator.
Visitor Centers
The Valley Visitor Center in Yosemite Village is the main information hub, with ranger programs, exhibits on geology and human history, and permit assistance. The Tuolumne Meadows Visitor Center operates seasonally. Both provide current trail conditions and bear activity reports.
Accessibility
Many valley-floor facilities, the paved bike path, and portions of key trails (including the Yosemite Falls lower loop and the Mirror Meadow loop) are accessible for visitors with mobility limitations. The free shuttle is accessible. The NPS maintains an accessibility guide on the official park website.
Medical and Emergency Services
Yosemite Medical Clinic is located in Yosemite Village and provides basic medical services; verify current hours locally. For life-threatening emergencies, call 911 — park rangers serve as first responders. The nearest full-service hospitals are in communities outside the park; serious cases may require transport by road or air.
Leave No Trace
Pack out all trash, stay on marked trails, avoid shortcutting switchbacks, and respect restoration closures. Wildflower and rock collection is prohibited. Drone use requires a special use permit and is restricted in most areas.
Safety
Wildlife
Black bears are active throughout the park and are attracted to food, scented products, and garbage. Never approach, feed, or surprise a bear. Store all food and scented items in provided bear boxes or an approved canister at all times. Report bear incidents to rangers.
Water and Altitude
All natural water sources should be treated before drinking — giardia is present in park waterways. Filters, purification tablets, or boiling are all effective. Tuolumne Meadows sits at approximately 8,600 feet; visitors arriving from sea level may experience mild altitude effects including headache and fatigue. Acclimatize gradually and stay hydrated.
Trail Hazards
Rapid snowmelt in spring can make trails slippery or obscured. River and creek crossings can be dangerous during high water in May and June — several drowning fatalities have occurred near seemingly calm water above waterfalls. Obey all barriers and posted warnings. Lightning is a serious hazard in the high country during summer afternoon thunderstorms; descend exposed ridges before midday if storms are forecast.
Heatstroke and Sun
Valley temperatures can exceed 100°F (38°C) in July and August. Hike early in the day, carry adequate water, and recognize signs of heat exhaustion. Sun intensity at elevation is greater than at sea level even when temperatures feel moderate.
