San Francisco to Yosemite: Every Way to Get There

Highway 120 or Highway 140

Highway 120 enters the park at the Big Oak Flat entrance and is the route the tour buses use when they stop at Tuolumne Grove, which sits just past Crane Flat. Highway 140 runs through Merced and enters at Arch Rock, climbing the Merced River canyon through El Portal. The park service gives the same 4 to 5 hour driving time for either route, and the distance is about 195 miles by either one.

Highway 140 has one practical advantage in winter: it needs chains less often than Highway 120 or Highway 41. That matters because chain controls are likely on the approach roads roughly from November to March.

• Highway 120 via Big Oak Flat: about 195 miles, 4 to 5 hours, passes Tuolumne Grove and Crane Flat.
• Highway 140 via Merced and Arch Rock: about 195 miles, 4 to 5 hours, fewest chain requirements of the three approach roads.
• Highway 41 via the South Entrance: the third approach, and the road to Mariposa Grove and Glacier Point once inside.

Do Not Trust Your GPS Blindly

The park service warns that GPS units do not always give accurate directions to Yosemite and tells drivers to follow the road signs instead. This is an official warning, not a small-print footnote. Drivers have been routed onto roads that do not reach the valley or that add hours.

Check the route on a map before you leave, and treat the signs on Highway 120 and Highway 140 as the final word once you are close.

• Download an offline map before the eastern valley, where cell coverage is patchy.
• Cell service inside the park is mostly limited to the eastern valley.

Chain Controls from November to March

Chain controls on the approach roads are likely from roughly November to March. California uses three levels. At R1, chains are required except on two-wheel drive or four-wheel drive vehicles with snow tires.

At R2, chains are required except on four-wheel drive or all-wheel drive vehicles with snow tires. At R3, chains are required on every vehicle. Rental cars rarely come with chains, so if you drive in winter, buy or rent them and know how to fit them before the day.

Choosing Highway 140 lowers the odds you will need them, but it does not remove them.

• R1: chains required except 2WD or 4WD with snow tires.
• R2: chains required except 4WD or AWD with snow tires.
• R3: chains on every vehicle, no exceptions.

Parking, Fees and the Car Maths

Parking in Yosemite Valley is free but limited, and on busy days the lots fill. There is no timed-entry or vehicle reservation for Yosemite in 2026, so arriving early is the only real strategy. The entrance fee for a private car is $35 per vehicle, valid for 7 days.

Add the fuel for roughly 390 miles round trip and the wear on your day, because the park service's 4 to 5 hours each way means 8 to 10 hours behind the wheel if you go and return the same day.

How the Connection Works

Amtrak San Joaquins runs from the Bay Area to Merced. From Merced, the YARTS Highway 140 bus, operated as an Amtrak Thruway connection, continues into Yosemite Valley, stopping at Yosemite Valley Lodge and Curry Village among other stops. An Amtrak ticket bought through to Yosemite bundles the bus ride and park entry into one purchase, which is simpler than buying the legs separately.

• Leg 1: Amtrak San Joaquins from the Bay Area to Merced.
• Leg 2: YARTS Highway 140 bus from Merced into Yosemite Valley.
• Through ticket: one Amtrak purchase covers the bus and park entry.

What YARTS Costs and What the Fare Leaves Out

YARTS on its own costs $22 one way or $44 round trip for an adult. Seniors aged 62 and over and children aged 6 to 17 pay $11 one way. Two things the fare does not include: the park entrance fee and the nonresident surcharge.

If you buy YARTS separately rather than as an Amtrak through ticket, you settle entry at the gate yourself. The service runs all year on Highway 140, with a summer schedule from about late May to the end of September and a winter schedule from the start of October. There is no service on Thanksgiving, Christmas, New Year's Day or Easter Sunday.

Several buses a day leave Merced for the valley, and timetables change by season, so use the YARTS trip planner before committing.

The Honest Time Maths

Public transport removes the driving but not the distance. You still face the full journey each way, plus waiting for connections in Merced. A same-day return by train and bus gives you less time in the valley than driving your own car at dawn, because you travel on the bus schedule rather than your own.

If Yosemite is the main purpose of your trip and you only have one day, weigh this carefully against a guided option such as the Extranomical Yosemite and Giant Sequoias day tour at $224, which leaves San Francisco between 5:20 AM and 6:00 AM and reaches the park early.

What Was Happening Late in the 2026 Season

These conditions change often, but they show the kind of disruption to expect. Big Oak Flat Road, which is Highway 120, was open with 15-minute weekday delays for vegetation work between Foresta and Crane Flat. Highway 140 and Highway 41 were open.

Tioga Road was open with construction delays and no overnight parking from mid October. Glacier Point Road was temporarily closed for wildfire smoke and firefighting. The Glacier Point road normally opens from about late May to October or November and can shut at short notice for snow or fire.

• Highway 120: open, 15-minute weekday delays between Foresta and Crane Flat.
• Highway 140 and Highway 41: open.
• Tioga Road: open with construction delays, no overnight parking from mid October.
• Glacier Point Road: temporarily closed for smoke and firefighting.

Seasonal Limits That Change What You Will See

Two seasonal facts change the day depending on when you go. Waterfalls peak in May and often stay strong into June with the snowmelt, but Yosemite Falls is often a trickle or dry by August. Bridalveil Fall flows all year, reduced in late summer.

In winter, the chain controls described above apply, and Glacier Point Road closes for snow from about November. None of this is a reason not to go, but a driver who arrives in August expecting a thundering Yosemite Falls will be disappointed. The best time to visit Yosemite page covers the seasons in detail.

Why Tours Absorb This for You

A tour operator drives these roads regularly and rechecks conditions before departure. If Glacier Point Road shuts for fire, the 2-day tour with lodging at $629 and the private tour at $1,200 both list Glacier Point only weather permitting, so the itinerary shifts rather than your plans collapsing at a closed gate. If you drive yourself, a closure discovered at the entrance is your problem to solve, and the alternative route can add an hour or more.

The Full Comparison

The table sets the options side by side. Car figures come from the park service fee and driving pages, YARTS figures from the YARTS fare page, and the tour figures from the lowest-priced day tour listing on this site, the Gray Line coach at $199. Prices are per person unless stated.

What a Tour Removes from the Day

A tour takes the driving, the parking hunt and the navigation off you. Pickups run between 5:20 AM and 6:40 AM depending on the operator, either at your hotel or at a downtown stop. The Gray Line full day tour departs Fisherman's Wharf at 6:20 AM and Union Square at 6:40 AM with no hotel pickup, which is why it is the cheapest listed day at $199.

The trade is control: about 4.5 to 5 hours in the park, of which a sequoia grove hike takes a share, and lunch is not included on any tour. Whether that trade is worth it is discussed on the page asking is a Yosemite day trip worth it.

• Pickup windows: 5:20 to 6:00 AM on Extranomical tours, 5:30 AM on the small-group van, 6:20 and 6:40 AM on Gray Line.
• No driving, no parking, no chain controls for you to fit.
• Fixed time in the park, about 4.5 to 5 hours on a day tour.

The Fee Both DIY Options Share

One cost catches many international visitors who travel independently. Since the start of 2026, every visitor aged 16 and over who is not a U.S. resident pays an extra $100 per person to enter Yosemite, on top of the $35 car fee or the standard per-person fee. The $250 America the Beautiful non-resident annual pass waives it and covers up to 4 people traveling together.

Tours collect it too in almost every case, after booking or at the gate, so it is never a reason to avoid a guided day. The full breakdown sits on the Yosemite nonresident fee page.

The Sights on Every Route

Tunnel View shows El Capitan, Half Dome and Bridalveil Fall in a single frame, and it sits on the road in from either direction of travel through the valley loop. El Capitan rises over 3,000 feet above the valley floor, with its summit at 7,573 feet. Half Dome rises nearly 5,000 feet above the valley, summit 8,842 feet.

Bridalveil Fall drops 620 feet and flows all year. Yosemite Falls totals 2,425 feet, one of the tallest in North America, with the upper fall alone at 1,430 feet. The free valley shuttle runs from about 7 AM to 10 PM and is wheelchair accessible, which stretches limited time further than walking between stops.

• El Capitan: over 3,000 feet of valley wall, summit 7,573 ft.
• Half Dome: nearly 5,000 feet above the valley, summit 8,842 ft.
• Bridalveil Fall: 620 ft, flows all year.
• Yosemite Falls: 2,425 ft total, often dry by August.

Sequoias, and the Detour Most DIY Drivers Miss

Tuolumne Grove sits on Highway 120 just past Crane Flat, so it is an easy stop if you drive in on 120 or take a tour that uses that road. The park service gives the walk as 2.5 miles round trip, a 1-mile descent each way with 500 feet of elevation change, taking 1 to 2 hours. The grove holds about two dozen mature giant sequoias.

Mariposa Grove, near the South Entrance, holds the Grizzly Giant at about 2,995 years old and 209 feet tall, but it lies about 1 hour 15 minutes from the valley, which is why no San Francisco day tour goes there. The giant sequoias in Yosemite guide compares the groves.

Food, Fuel and Signal

Lunch is not included on any tour, and the same applies to DIY drivers: buy it in the valley. The Base Camp Eatery at Yosemite Valley Lodge runs a food court with a Starbucks counter, Degnan's serves Yosemite Village, and the Village Store sells groceries. Opening hours change by season.

Cell coverage is mostly in the eastern valley on AT&T, T-Mobile and Verizon, and patchy elsewhere. Two rules to know before you park: drones are banned throughout the park, with up to 6 months in jail or a $5,000 fine, and nothing scented may be left in sight in a car because of bears, with fines up to $5,000.

• Base Camp Eatery at Yosemite Valley Lodge: food court with Starbucks.
• Degnan's in Yosemite Village, plus the Village Store for groceries.
• Drones banned, up to 6 months in jail or a $5,000 fine.
• Food and scented items stored out of sight, fines up to $5,000.
