Unfortunately, TMR is not open for weekend trips. You can only book day trips, here is the direct link to book at Ten Mile River- https://campreservation.com/640/Camps/556

You can create an account if you plan to make multiple reservations, or you can book as a guest!  

Scroll down and look at the facilities before booking, and then there is a button at the top right to make a reservation. The system will walk you through the reservation process.
