Great news! We will be officially opening Red Sleep Drive for the summer on Friday, May 8th. At this time, we will be switching to our summer hours: Bison Range 7am - 8pm | Front Gate 7am - 7pm | Visitor Center 7am - 7pm.
Day Passes are $20/regular vehicle, $35/vehicle with +10 seats, and $60/commercial tour vehicle. Annual Passes are $60/vehicle. CSKT Tribal Members can pick up a free day pass with their Tribal ID.
As a reminder, we stop allowing visitors on the upper drive at 6pm, which is when we close the inner gate. Anyone on the drive at this point will have until 8pm to leave the Bison Range. Be sure to arrive by at least 5:45pm to give yourself enough time to get a pass and get on the upper road before the gate closes. Visitors will be able to continue getting passes for Prairie Drive until 6:55pm.
For anyone who isn't familiar with Red Sleep, this is the one-way upper road, which goes over Red Sleep Mountain. Combined with Prairie Drive (the lower road) it forms a 2-hour loop. It is unpaved, with switchbacks and a 10% downgrade on the back.
There are two walking trails up top, Bitterroot Trail (1/4 mile) and High Point Trail (1/2 mile), which are the only places you are able to get out of your vehicle and walk around. We also get a lot of bears in this area, so be sure to keep food inside your vehicle and stay bear aware!
