3 nights stay minimum
Though nearly all private vehicles must turn around at mile 15, Savage River, Tek campers are an exception to that rule. If you wish, you may drive your vehicle / RV to Tek. The trade-off is that you must make, at minimum, a three-night stay, and your vehicle must stay in your campsite for the duration of your stay. Your vehicle can only leave your campsite when you are ready to travel back to the park entrance.
If you are tent camping, you may wish to use the camper bus to access the campground. If you arrive in Tek via bus, rather than your own vehicle, there is no minimum number of nights you must stay.
No firewood is available for sale at Teklanika, so be sure to bring any with you before traveling to the campground. Firewood can be purchased in many locations outside of the park, or at the Riley Creek Mercantile.
