Getting around in spring
Check the seasonal access and equipment decisions before fixing the route.
Check the roads for your date
Interior opening dates change with plowing and weather. The northern corridor has a different normal calendar.
Keep wildlife viewing safe
Give animals room and observe from designated stops. Stay on thermal boardwalks and established trails.
Things to do in spring
Choose a lower-elevation or high-country outing for the actual conditions.
Lamar Valley
Spring calving and emerging bears bring wildlife interest. Use binoculars and keep a safe distance.
Mammoth Hot Springs
A northern-range base gives access to the hot-spring area when local routes and boardwalks permit.
Old Faithful
Add the geyser basin only after confirming the interior route and visitor services that your day needs.

Where to stay in spring
Match the overnight base to the roads and park area your dates allow.
Mammoth area
Mammoth Hot Springs Hotel is near the North Entrance, a useful location for northern-range planning. Check its own seasonal calendar.
Interior park lodges
Compare the individual lodge’s operating dates before planning a geyser-basin or lake-area stay. Confirm the road approach separately.
Camping Campgrounds have individual calendars and booking arrangements. Confirm the campground and approach rather than assume a full-park camping season.

How we built this page.
An independent guide using official data. Not affiliated with or endorsed by the National Park Service.
- Official guidance
- NPS and the relevant operators. The linked official pages support the access, facilities and rules described here. Confirm details before traveling.
- Crowd context
- 2021–2025 monthly averages. NPS recreation visits describe normal seasonal demand, not trail congestion, parking availability or unique visitors.
- Schedules and conditions
- Planning patterns, not live status. Seasonal information describes the normal pattern or explicitly dated source schedule. Current conditions are handled separately. The official source is the place to confirm today’s access.
Topic sources and data details
NPS seasonal, activity and overnight guidance supports the normal patterns and named choices on this page. Check the linked official pages for current operation and booking details.
Month choices describe the reviewed planning window. Monthly recreation visits are full-calendar-month 2021–2025 averages, including any month partly inside the window.
Temperatures are NOAA 1991-2020 normals at Yellowstone Park, Mammoth, WY; Mammoth is Yellowstone HQ at 6,194 ft. The northern-range districts (Lamar Valley, Tower) read close to these numbers. Old Faithful (7,365 ft) and Norris (7,484 ft) typically run 5-8°F colder; Yellowstone Lake (7,733 ft) and high passes colder still. Lake Yellowstone has its own NOAA station (USC00485345) at 7,892 ft if you need higher-elevation numbers.
Seasonal highlights mark the editorial month window, not guaranteed access or travel-date weather.
