Family Friendly A flat and relatively easy loop.

Closes at dusk.


This trail is not one to miss. Whistle Lake is astoundingly beautiful year-round; enjoy the secluded charm of the crystal clear waters of Whistle Lake. The trails are mostly flat and there are not many obstacles, which makes it a good option for families.

Need to Know

There is a short foot bridge over a stream leading to Toot Swamp... hey, I didn't name it.


The parking for this loop hike is at the end of Whistle Lake Road. From the parking area, head south on Trail 20, a nice level doubletrack. Take the trail to its end by the north end of Whistle Lake, passing Trail 21 and Trail 204 which both head off to the left. From the doubletrack, pick up the singletrack Trail 205, which heads south around the eastern and southern perimeters of Whistle Lake. The trail climbs a moderately steep hill on the southern ends of the lake, and can be rocky and rooty in places.

The singletrack ends at Trail 22. Take a right onto Trail 22, then another right onto Trail 21, both rather mellow double tracks. About 2.3 miles into the hike keep an eye out on the right for Trail 204, a singletrack that heads off Trail 21 to follow the edge of the lake north. Trail 204 ends back at Trail 20 at the north end of the lake. To return to your car, turn left and head north back to the parking lot.

If you have the chance, swimming to Whistle Lake Island is a ton of fun (there are cliff jumping areas around Whistle Lake also)! Whistle Lake and the surrounding areas make you feel as if you are deep in the Pacific Northwest tundra, miles from civilization. Take a deep breath in and you can hear nature's song in this tranquil forest.

Flora & Fauna

Ferns, ivy pines, deer, and more!

Easy Stroll. It's a little confusing but just follow the signs and once you get to the lake follow it all the way around back to the parking area 3mi

The trail as it is engulfed in the forest.
