Larrabee State Park requires the use of a Discover Pass for every vehicle that enters the park.
Also know as Hush-Hush, Lower Salal Trail packs a lot into a short trail. Ratcheting, lunges, and the occasional foot dab are all part of the forward process as you battle over and around roots. While there isn't much elevation gain, the effort of scrambling over so many obstacles certainly makes this a technically as well as physically demanding trail.
The most challenging section comes at the halfway mark, with a complex rock garden beneath a suspended log (you'll recognize it clearly). From there the trail backs off on the difficulty and opens up the speed before joining back onto the North Lost Lake Trail.
