Activity Notes

This trip is not suitable for beginners. Join me for a hike from the Tilly Jane sno-park along the Tilly Jane ski trail to the Tilly Jane A-frame. Depending on conditions we may need to use snowshoes. Micro-spikes are a good idea regardless. After a break there we will go perform a check of the wildlife camera operated by Cascadia Wild and the US Forest Service near the A-frame before we retrace our steps. Visiting the camera does require off-trail bushwhacking and signing a liability waiver.

One-way: About 3.5 miles with 2500 feet of elevation -- total mileage is about 7 miles round-trip.
