Exceptionally clean and the sites are well spaced. The reservoir gets busy with motorized boat traffic racing in circles with screaming teens, which is unfortunate. Puts a damper on an otherwise excellent spot.

Great campground! We had a double spot which proved plenty of space. Our spot was adjacent to the lake but hidden by trees providing privacy, shade and access to lake. Cleanest bathrooms I have seen for a non-flush toilet.

This camp is phenomenal- the camp hosts were incredible, and the nature is beautiful and diverse. The bathrooms were so super clean, smelled good and had hand sanitizer, the water from the spicket was clear and fresh, and the best ever was the lake and the docks. We swam daily- super clear water and a family friendly lake. We loved it- a bear walked by our camp, a huge beautiful grizzly, but we had no problem. Just bear proof your camp!

A beautiful campground next to Island Park Reservoir. The bathrooms on B loop have been recently remodeled and were immaculately clean. The campground was quiet and clean. Note that you are not allowed to ride ATV/UTVs in the campground but there is a good spot to park them right at the entrance near the camp host. We actually appreciate not having them in the campground. Made for a more relaxing, less dusty camping adventure.

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

- Individual campsites: cancelling after 12:00am local time the day before arrival usually means a $10 cancellation fee plus forfeiting the first night's fee.

- Modifications are allowed before the cut-off window, but fees depend on the change. Changing to dates completely outside the original reservation dates may trigger a $10 change fee.

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