What to Know Before Visiting Yosemite National Park

Question

Accepted Answer

Direct answer

Yosemite National Park requires planning: know entrance/permit rules, crowded seasons, weather hazards, and limited services. Prepare for altitude, wildlife, and variable cell service.

## Entry & Permits

- Entrance fee: Park entrance fee (per vehicle or per person for walkers/cyclists). Check the National Park Service (NPS) site for current fees.
- Reservations: During peak periods (spring–fall weekends and busy summer months), Yosemite may require timed entry reservations or campground/hotel reservations — confirm on NPS before you go.
- Wilderness permits: Required for overnight backpacking into Yosemite Wilderness. Apply in advance (quota systems may apply).
- Special permits: Rock climbing, commercial guiding, and certain activities need permits from the park.

## Best Time to Visit

- Late May–June: Waterfalls at peak flow, wildflowers, good weather. Popular but spectacular.
- July–August: Warm and dry, but hottest, driest, and most crowded. Some fall-in snow-free high country trails are accessible later summer.
- September–October: Fewer crowds, milder weather, great for hiking and photography; some services begin to close in late fall.
- Winter (Dec–Mar): Snow and ice transform the park; some roads close (e.g., Tioga Road, Glacier Point Road). Great for snowshoeing and quiet scenery—bring chains and winter gear.

## Safety Tips

- Weather/Altitude: Temperatures can vary widely. Nights are cold, even in summer at higher elevations. Hydrate and acclimatize if coming from low elevations.
- Waterfall and river hazards: Strong currents and slippery rocks make swimming near falls dangerous. Heed warning signs and barriers.
- Rockfall and ice: Trail conditions can include ice, loose rock, and falling debris—use caution and traction devices in winter/spring.
- Wildlife: Do not approach or feed wildlife. Store food and scented items in bear-proof lockers where provided (bear canisters required for some backcountry). Observe bears, deer
