The group campground is in its own separate area. We had more than enough space for our training retreat. The rangers were extremely helpful in getting everything set up and figured out for our ever-changing list of RSVPs. For groups, you can have the rangers do a special program just for your group---highly recommended!! They do a good job keeping up with cleaning. Lots of great information about the natural features and Native American history. Make sure you follow all the regulations regarding bears...we saw paw prints out on hikes. This is pretty far away from any stores, so make sure you have everything you need before entering the park. Excellent basecamp for long hikes in the area.
