If you're planning to run any part of this trail, show up early; the trailhead parking area only holds about 30 cars. You'll need a Discover Pass ($35 annual, or $11.50 day pass) to enter. In the eastern reaches of the park, you may hear gunfire from the nearby shooting range.

Wynoochee Lake reveals a breathtaking scenery defined by steep, rugged peaks adorned with lush conifer forest that rise above a glistening crystal clear body of water. At this end of the lake there is a picnic area and dam which makes a nice short out and back route. And if you're feeling more adventurous, you can embark on the 12-16 mile loop that encircles the entire lake (distance may vary depending on the safety of the Wynoochee River ford)
