How Many Days Do You Need in Yellowstone?

How Yellowstone is laid out

Most sights sit along the Grand Loop Road, a 142-mile figure eight. The lower loop links Madison, Old Faithful, West Thumb, Yellowstone Lake, Canyon and Norris. The upper loop links Norris, Canyon, Tower-Roosevelt and Mammoth Hot Springs. Five entrance roads feed into it from the North, Northeast, East, South and West.

The speed limit is 45 mph unless posted lower, and traffic often stops for bison, bears and construction. Driving the lower loop with no stops takes roughly 3.5 to 4 hours using NPS average times, and the upper loop about 3 hours. Add stops, parking and wildlife jams, and one loop fills a full day.

That is why the number of days you need depends less on what you want to see than on how much driving you are willing to do. Splitting the park into areas, and moving your base partway through, saves hours.

Drive times between major junctions

These are the average drive times NPS publishes. The park notes they can be much longer because of wildlife on the road, weather and road projects. North Entrance to Mammoth takes about 15 minutes, and Northeast Entrance to Tower Junction about 60 minutes.

1 day in Yellowstone

With one day, focus on the lower loop's west side and the canyon. This plan assumes you enter at the West Entrance and leave the same way, with about 4 to 4.5 hours of driving at NPS average times.

Start at Old Faithful early, before the parking lot fills. NPS put the median eruption interval at about 102 minutes as of January 2025, and rangers post predicted times at the visitor education center. Walk the Upper Geyser Basin boardwalks while you wait.

Drive north to the Fairy Falls parking lot, 1 mile south of Midway Geyser Basin, and hike the 1.2-mile round-trip Grand Prismatic Overlook Trail. Parking is very limited, so a midday slot may mean waiting.

Continue to Norris Geyser Basin, then 30 minutes east to Canyon. See the Lower Falls, which drop 308 feet, from Artist Point on the South Rim. Head back through Norris and Madison to the West Entrance, or drive south from Canyon into Hayden Valley at dusk first if you have the energy.

2 days in Yellowstone

Two days covers the lower loop well. Stay near Old Faithful or in West Yellowstone the first night, then at Canyon or Lake the second if you can book it, to cut the backtracking.

Note that Biscuit Basin, between Old Faithful and Midway, remains closed after its 2024 hydrothermal explosion.

• Day 1, geyser country: Old Faithful and the Upper Geyser Basin in the morning, Grand Prismatic Overlook Trail and Midway Geyser Basin midday, then Fountain Paint Pot and the Firehole Lake Drive area on the way back to Madison.
• Day 2, canyon and valley: Norris Geyser Basin early, then the Grand Canyon of the Yellowstone. Hike the Brink of the Lower Falls Trail (0.7 mile round trip, steep) and stop at Artist Point. Drive south through Hayden Valley to Yellowstone Lake, then return by way of West Thumb and Old Faithful or back through Canyon.

3 days in Yellowstone

Three days lets you add the upper loop and the northern range, which is the best wildlife country in the park. The Lamar Valley morning is the reason to plan this order: animals are most active early, and Canyon is closer to Lamar than the geyser basins are.

Exit through the North Entrance at Gardiner, 15 minutes past Mammoth, or loop back to the West Entrance through Norris and Madison.

• Day 1: geyser basins, as above.
• Day 2: Norris, Grand Canyon of the Yellowstone, Hayden Valley at dusk.
• Day 3: leave Canyon before sunrise and cross Dunraven Pass to Tower Junction (50 to 60 minutes), then drive east into Lamar Valley for bison, pronghorn and a chance at wolves. Finish at Mammoth Hot Springs to walk the travertine terraces.

4 days in Yellowstone

Four days lets you slow down and see the lake country. Use the extra day around Yellowstone Lake: the West Thumb Geyser Basin boardwalk on the lakeshore, the Lake Village area and the Fishing Bridge stretch of the Yellowstone River.

Or spend it on a longer walk. The Lone Star Geyser trail near Old Faithful is a 4.8-mile easy round trip from the Kepler Cascades pullout, and it is open to bikes. Wildlife watchers often use a fourth day for a second dawn in Lamar or Hayden Valley.

If you are continuing to Grand Teton, leave through the South Entrance. Grand Teton charges its own entrance fee.

• Day 1: Old Faithful, Upper Geyser Basin, Grand Prismatic Overlook.
• Day 2: West Thumb, Yellowstone Lake, Hayden Valley at dusk.
• Day 3: Grand Canyon of the Yellowstone and Norris.
• Day 4: Lamar Valley at dawn, Tower area, Mammoth Hot Springs.

Where to base yourself

Yellowstone is too big for one base to work well for every day. Most visitors do best with two: one on the west or south side for the geysers, and one on the north side or at Canyon for the canyon and wildlife valleys.

• West Yellowstone, Montana (West Entrance): 30 minutes to Madison Junction, the shortest drive to the geyser basins. Busy in summer.
• Gardiner, Montana (North Entrance): 15 minutes to Mammoth Hot Springs, at the start of the only park road open to cars all year. Good for Lamar Valley and winter trips.
• Cooke City and Silver Gate, Montana (Northeast Entrance): about an hour to Tower Junction, with Lamar Valley on the way. Small and remote; summer access from the east is via the Beartooth Highway, open late May to mid-October.
• Cody, Wyoming (East Entrance): the East Entrance is about an hour from Lake Village, plus the drive from town. Best if you arrive from the east.
• Jackson, Wyoming and Grand Teton (South Entrance): 50 minutes from the South Entrance to Grant Village. Good if you are pairing the two parks.
• Inside the park: lodges at Old Faithful, Canyon, Lake, Grant Village, Mammoth and Roosevelt, plus campgrounds such as Madison, Canyon, Bridge Bay, Grant Village and Mammoth. Staying inside removes the entrance drive each morning.

Booking and practical tips

Yellowstone does not use a vehicle reservation system. You need an entrance pass, $35 per private vehicle for 7 days in 2026, and non-U.S. residents age 16 and older pay an extra $100 per person unless they hold an annual or America the Beautiful pass.

Lodging and camping inside the park are what fill up. Campground reservations open on a rolling basis six months ahead on Recreation.gov or through the park's lodging concessioner, depending on the campground, and NPS advises booking lodges as early as possible.

Start each day early, keep the gas tank above half, and download offline maps, since cell coverage is limited. Road projects in 2026 included work on the Gardner River High Bridge near Mammoth, with delays of up to 15 minutes, and on several other bridges, so check the Park Roads page the morning you drive.
