Northwest Forest Pass or equivalent required.

This trail will have snow covering much of it; microspikes and poles are highly recommended.

Trip reports as of March 19th say the trail is snow-covered from the trailhead, although the snow is packed down enough that folks can hike without postholing. I expect the lower part to melt out between now and April 11th, but anything past the junction with Granite Mountain trail may be snow-covered. Waterproof boots, microspikes, trekking poles, and gaiters - while not required - are strongly encouraged to make sure you enjoy the hike and stay dry. Feel free to email me if you have any questions.

Please remember to follow all of the required COVID protocols. You must have the required face covering (mask, neck gaiter, bandana) and hand sanitizer in your possession to participate in this hike. The face covering must be able to cover the mouth and nose when we pass close to others. Be prepared to step off the trail or turn outward when passing other hikers and maintain social distancing. Carpooling is limited to household members.
