Mount Rainier by season
Winter Fair
Paradise gets enormous snowfall and becomes a snowshoe and sledding destination. The road from Longmire to Paradise is the only route kept open, and it can close in storms.
Spring Fair
Snow still covers Paradise and Sunrise. Lower forests around Longmire and Carbon River are quiet and green, and roads open gradually through late spring.
Summer Good
Prime time. Sunrise Road opens in early July, trails melt out, and subalpine wildflowers usually peak from late July to mid-August.
Fall Good
Huckleberry and mountain ash turn the meadows red and gold in late September. Weather turns quickly in October, and Sunrise Road closes for the season.
What to do
- Walk the Skyline Trail at Paradise
- Watch sunrise at Sunrise (6,400 ft, the highest point you can drive to)
- Hike to Tolmie Peak Lookout
- See the Grove of the Patriarchs
- Catch reflections at Reflection Lakes
Local tip
