Mount Rainier Operating Hours & Seasons
When You Can Visit Mount Rainier National Park
Mount Rainier National Park is open to visitors all year round, although getting there isn’t always an easy task! The park is busiest during July and August, the warm dry weather and the beautiful wild flowers really bring out the visitors in force, so if you plan to visit Mount Rainier National Park during those months then be aware that parking might be a bit of a problem on holidays and weekends, it’s usually less crowded mid-week if you can possibly make it.
Summertime isn’t necessarily the best time to visit Mount Rainier National Park though, there’s something new and exciting to see whatever the season.
Spring is the time when the waterfalls are at their very best, but in the fall you’ll be amazed at the brilliant colors which reach deep into the valleys of Mount Rainier National Park. The weather is going to be a little less predictable (although the one thing you can predict about Mount Rainier National Park is that the weather is always unpredictable). Some of the facilities in the park may not be open during these months too, and it’s even more important that you do a pre-check on the status of the roads, the trails, activities and campgrounds before you arrive.
During the winter time you’ll only be able to access Mount Rainier National Park by road from the Nisqually entrance in the southwest corner. There is another entrance which is often open at Carbon River, but you can only park there, then you have to continue on foot or by bicycle.
