Notices from Recreation.gov

Utility hookups are not available

Off-road vehicle use is prohibited within the campground

In accordance with standard industry practices, Mount Hood Recreation will be assessing an additional vehicle fee on the second vehicle in each single family campsite, and on the third and fourth vehicle in any double family campsite, provided these vehicles are not joined to the first vehicle by a hitch and towed onto the site. In the case of motorcycles, the first two are considered as one vehicle for determining additional vehicle fees. The third and fourth motorcycle would also be considered as one vehicle. No additional vehicle fees are collected for bicycles

Fire Restrictions: Fire restrictions may be imposed at any time due to hot, dry weather conditions, at which time campfires and charcoal fires may not be allowed.

Refunds: Refund requests made through www.recreation.gov will be charged a $10 processing fee. This fee is retained by the reservation service contractor along with the non-refundable reservation fee. All requests for the return of the non-refundable reservation fee and the cancellation fee will be declined by the campground concessionaire as they did not receive these fees (these are the fees retained by the reservation contractor, a different entity).

Don't Move Firewood: Please protect Pacific Northwest forests by preventing the spread of invasive species. Firewood can carry insects and diseases that can threaten the health of our western forests. You can make a difference by obtaining and burning your firewood near your camping destination. Visit Dontmovefirewood.org for further information.
