The Radio Peak Trail travels for just under half a mile in the northern reaches of Cougar Mountain. It is part of the vast trail network in the park and does not have its own devoted trailhead.

Start out from the Sky Country Trailhead travelling east on Clay Pit Road for about 1000 feet before reaching the turn off for Coyote Creek Trail on your left. Take this for half a mile. At the first fork turn left on the Radio Peak Trail.

The Radio Peak Trail climbs gently to a high point before ending at the park boundary. Along the way a short spur trail splits off to connect with an adjoining neighborhood.
