Recreation
Hikers will find more than 30 miles of trails that journey down into the crater for exploring its many features. There is no shade or water on the crater floor, and temperatures can vary significantly, so pack along plenty of water and sunscreen. Also, due to the soft sandy nature of the trails, plan on spending twice as much time to hike out as to hike in. A self-guided trail begins at the Hosmer Grove campground and ends at the campground. If you are a bird watcher the early dawn is great viewing of the many native birds in the area, making this a beautiful early morning hike.
