San Francisco Sierra Loop: 4 Wild Days
Four days is where the 3-day Sierra Loop stops feeling rushed: the same Yosemite-then-Tahoe route, but with a full unhurried Valley day inserted before Tioga Pass instead of squeezing Yosemite into a single morning. The 5-day version does the same trick for Tahoe next. Spend a couple of days in the city itself first with the in-city 3-day itinerary before starting this loop.
Book these before you go
- Rent the car in San Francisco; there’s no rental counter inside Yosemite.
- Yosemite gateway lodging for two nights, South Lake Tahoe lodging for the last one.
- A Yosemite Valley floor tour if driving and sightseeing both in one day sounds exhausting.
The four days at a glance
| Day | Focus | Distance/drive-time |
|---|---|---|
| 1 | San Francisco to Yosemite | 170 mi / 3.5-4 hrs |
| 2 | Full Yosemite Valley day | In the park, no drive |
| 3 | Tioga Pass to Lake Tahoe | 2.5-3 hrs on Hwy 120 east |
| 4 | Tahoe morning, drive back to SF | 190-220 mi / 3.5-4.5 hrs |
Do you need a Half Dome permit for this trip?
Only if summiting is actually the plan, and it isn’t part of this itinerary. Half Dome’s cables require a separate lottery permit applied for months in advance, not something bought at the gate, so most four-day visitors are better off treating the summit as a view from the Valley floor rather than a to-do list item. Everything on this route needs nothing beyond the standard entrance fee.
Day 1: San Francisco to Yosemite
Pick up the rental car and take Highway 120 through Groveland, roughly 170 miles and 3.5 to 4 hours depending on summer traffic at the entrance. Standard entry runs $35 per vehicle for seven days ; non-US residents 16 and older owe an added $100 per person under a January 2026 fee change, worth weighing against a $250 annual pass covering three more adults. There’s no 2026 day-use reservation system , so the wait is at the gate rather than online. Check into Groveland, then catch Tunnel View and a short Bridalveil Fall walk before dark.
Day 2: A full day in Yosemite Valley
Park once and let the free shuttle handle the rest; lots fill by mid-morning regardless of reservations. Walk the Mist Trail as far as Vernal Fall, or push on to Nevada Fall if the legs are up for it, then use the afternoon for Glacier Point Road if it’s open for the season, the classic across-the-valley view of Half Dome without the permit. A full day here, rather than a rushed morning, is the entire point of choosing this itinerary over the 3-day version.
Day 3: Over Tioga Pass to Lake Tahoe
Tioga Road opened May 15, 2026 , the earliest start in eleven years, and closes again with the first serious autumn snow, so confirm current status before counting on this route outside summer and early fall. The drive east through Tuolumne Meadows and down to the Tahoe basin runs 2.5 to 3 hours, genuinely different high-country scenery from the Valley floor. Check into South Lake Tahoe with the afternoon free for a first look at the shoreline.
Day 4: Tahoe morning, then home
A slower morning at Emerald Bay or along the west shore before the drive back; summer means the lake and hiking, winter flips this same route to ski resorts and required tire chains. Highway 50 or Interstate 80 covers the 190 to 220 miles back to San Francisco in 3.5 to 4.5 hours, and either road can close outright in a serious storm.
Is renting a car for just this loop worth it?
Yes, and it’s the only way to do it. Neither Yosemite nor Lake Tahoe has a train station or a useful bus link from San Francisco, so a rental car is the sole option for all four days, not an upgrade over some transit alternative. Rent it for exactly this loop, return it the evening you’re back, and let Muni handle the city on either side.
Getting around and one honest note
Nothing on this loop connects by train or bus; the rental car runs the whole four days, and returning it the day you’re back beats paying San Francisco’s $50-75-a-day garage rates for a car the rest of the trip won’t touch. Four days is enough to stop rushing Yosemite without yet giving Tahoe the same treatment, that’s what the 5-day version is for.
Book both gateway hotels before committing to exact dates; July and August fill Groveland and South Lake Tahoe alike weeks out.
