Camp Host Steve was the biggest douche bag I've ever dealt with in Island Park. Not friendly, drive around at night with no lights on his golf cart, come into our camp unexpectedly at night while we were having a campfire to discuss rules. You need to give this guy a job out in the desert in the summertime where nobody goes. We had over (10) spots and never in my life have people gone home early due to the camp host being a total prick but plenty from our group did. Good luck with Camp Host Steve.

It was easy to get parked as most sites were pull thrus, had nice space between campers. The camp host was great, we had a good time!

We had a nice stay. The restrooms were very clean. Access to Buttermilk is best via the paved road that takes you to Lakeside Lodge, even though there are no signs to direct you. Do not take the dirt road #126.

What a wonderful campground! You are surrounded by a beautiful pine forest, and the reservoir is just 2 minutes away. We stayed here for 5 days with an RV at the end of August-beginning of September, and we enjoyed every minute of it. The host was very kind and informed us about everything we needed to know. The campground didn't have water hookups, but other than that, it was really nice all around.

Policies & Rules

Cancellation policy

  • Reservation fees are non-refundable. For campsites, cabins, lookouts, yurts, group sites, and similar stays, we charge a reservation service fee of $8.
  • Standard cancellations usually have a $10 cancellation fee. Customers can generally cancel before the check-in date online.
  • Late cancellation rules differ by stay type.
    • 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.
    • Cabins, lookouts, and yurts: cancelling less than 14 days before arrival usually means a $10 cancellation fee plus forfeiting the first night's fee.
    • One-night reservations: a late cancellation usually forfeits the full amount paid, up to the total original reservation cost.
  • 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. Extending or shortening a stay that still includes original dates usually has no change fee, though refunds may depend on timing and facility rules. Switching to the same type of campsite for the same dates usually has no change fee, but price differences are charged or refunded.
  • Early departures may or may not be refunded. At certain facilities, partial refunds may be possible if staff can mark the site available for other visitors. No refund is given for a night if the early departure is requested after that day's check-out time.
  • Security deposits are separate. Security deposits may be refunded to the original payment method if the facility is left in acceptable condition, as determined by the property.
