Jack's Mailbox & Parley's Canyon Overlook Loop (Difficult)

This is a hard hike so please train and plan :) We will do this clockwise with a steep ascent to JM and then down to the BST. We will be doing a different version of the linked Alltrails hike, returning on the BST (not the road). The route we will do appears blue on the linked map and is gentle rolling with more elevation gain than the road route. Please bring spikes and/or poles. Sorry, no first timers.

I am giving priority to those that have done difficult hikes with me :)

Length: 5 mi +
Elevation gain: 2,500 ft +
Route type: Loop

Address for google//apple maps: 1835 Carrigan Canyon Dr, Salt Lake City, UT 84109
