Mount Rainier in March.

Crowd snapshot.

March averages about 24,000 recreation visits over 2021 to 2025, about 6% of July. That's a little below January and above February and December, the two quietest months. The 2025 count was 23,593. NPS notes the Paradise lot can fill quickly on sunny days even in winter, and rangers may meter traffic at the Longmire gate when it does, so a clear weekend can feel busier than the monthly number suggests.

Weather snapshot.

Longmire's 1991-2020 normals give March an average high of 44.6°F, a low of 27.7°F, 7.55 inches of precipitation, and 25.4 inches of snow. Only December and January average more snow at the station. Nights still average below freezing. Paradise sits at 5,400 feet, far above the station, and its trails and road stay snowy. NPS says avalanches are common in winter and spring, so check the avalanche hazard before you leave the parking lot.

Access snapshot.

The winter setup holds in March. Vehicle access in winter is only from the Nisqually Entrance, per the NPS hours page, and the gate between Longmire and Paradise closes nightly and typically opens at 9 a.m. if conditions allow. It can stay closed all day for weather, avalanche danger, or road conditions, so check the alerts before you go, as the NPS winter travel page advises. Every vehicle must carry chains until May 1, per the NPS tire chain FAQ. SR 123 and SR 410 are closed for winter, and Mowich Lake and the Carbon River side don't open until summer. Paradise Inn is closed, and the National Park Inn at Longmire is open, per the NPS lodging page. Check the NPS current conditions page for the closures and restrictions in force.

Seasonal events.

Ranger-guided snowshoe walks at Paradise are typically offered from late December through March, usually on Saturdays and Sundays at 11 a.m. from the Jackson Visitor Center, and they can be canceled for safety or staffing. The Paradise Sledding Area is generally open late December through mid-March, when there's enough snow and enough staff to run it, so check its status first. Snowshoe rentals at the Longmire General Store run through March, depending on snow. Skiers and snowshoers heading beyond the lot should carry an avalanche transceiver, probe, and shovel along with the 10 essentials, as NPS advises.

Audience verdict.

March is for winter visitors who want a bit more daylight and are still happy with chains and a gated road. Snowshoers and skiers get the last month of typical ranger walks and rentals. Families on spring break should check the sledding status first, because the area doesn't open every winter. It isn't a hiking month: Paradise trails are under snow, Sunrise and the east side are closed, and the campgrounds don't open until late spring.

Methodology

Monthly recreation visits come from the official NPS Visitor Use Statistics Data Package, 2025 on NPS IRMA Stats; the statistic shown is Recreation Visits, the 5-year mean for 2021-2025. Climate normals come from NOAA NCEI's 1991-2020 U.S. Climate Normals at Longmire Rainier NPS, WA (station USC00454764, 2,762 ft elevation). The access score weights the Nisqually-Longmire-Paradise corridor's day-use status, Stevens Canyon and Sunrise Road seasonal openings, and Carbon River/Mowich Lake vehicle access for typical wheeled-vehicle openings that month. NPS says no timed-entry reservation is required anywhere in the park in 2026.
