When to Visit...


With brisk temperatures and occasionally snow sticking around until May, Spring is a great season to hit the trails and catch the first signs of thaw and wildflower blooms. Due to possibly snowy conditions, the loop road and lava tubes are often not accessible until around April and can cut back on the amount of tourist traffic. As the month progresses, mid to late June remains an excellent middle ground for extended wilderness excursions, capturing peak blooming season and overall milder temperatures.


Summer can last from July well into August and is often complemented by warm temperatures during the day and gorgeous star-covered skies at night. Due to the high desert terrain, trail hiking adventures are recommended during the early morning hours for far-reaching views of the sunrise and moderate temperatures. As the day starts to warm up, take the opportunity to visit the cool interior of a lava tube to escape the heat. With so much territory to cover, it's easy to find solitude, regardless of the amount of pedestrian traffic.


As summer comes to a close and temperatures start to cool, the lack of wind can make for some of the most pleasant weather. By this time, most crowds clear out, ideal for visiting the area and more popular tourist destinations. Fall is another excellent time to head out into the wilderness for miles of backpacking adventures and the opportunity to capture the transformation of gorgeous autumn colors dominate the landscape. Find access to conveniently situated campsites and amenities often available into October.


By far the most prominent season, winter covers several months from November through March, depending on the year. The loop road usually closes by mid-November and opens up to cross-country skiing as soon as snow covers the ground. Snowshoeing and skiing are excellent ways to tour the park, with passage to around 5+/- miles of frequently groomed pathway and low visitor traffic.

Where to Start...

Visitor Center

Begin your adventure by stopping at the Visitor Center for a wealth of information, including maps, trail suggestions, upcoming presentations, guided hikes, and events. Wander through various exhibits and learn about the effects of volcanism and why it remains a point of interest for geologists, biologists, climatologists, N.A.S.A. research, and space mission training to this day. Due to the drastically similar volcanic landscape found on the moon, Craters of the Moon serves as a national hotspot for space research and continues to function as a regional location for astronauts to learn how to navigate a lava environment.

Things to Do...
