All Trails is having what looks to be their normal holiday sale of 50% off a one year membership. Searching, it seems like they do this Memorial Day 4th of July and Labor Day. Unfortunately it does not work on the 3 year membership.
With everyone seemingly going out to nature for their holidays during the summer of Corona this should be able to help you find new trails to hike that are maybe less crowded or just didn't know about. Works offline so you can get out to nature.
Offer ends July 6th
Previous threats noted that trail forks is better for mountain biking.
