We rented the group site for our 2 families - a beautiful, secluded setting, and very reasonably priced, especially on weekdays. The group site has its own bathrooms (amazingly clean vault toilets), and the onsite water hydrants were very convenient. The hosts were friendly but unobtrusive - they stopped in and warned us that bears had visited every campsite within the last week. As recommended, we stowed our stuff inside the provided bear boxes, and saw and heard no bears at all. We did see a cow moose several times, and woke at 3am to the thrilling sound of an elk barking nearby. There are plenty of things to do in the area. It was a short hike to the reservoir. We did a little evening trip to the spectacular Mesa Falls, and a day trip exploring Yellowstone - the west entrance is only about 35 minutes away. We came away with lots of good memories, glad we chose this place.

- Standard cancellations usually have a $10 cancellation fee. Customers can generally cancel before the check-in date online.

Switching to the same type of campsite for the same dates usually has no change fee, but price differences are charged or refunded.
