Local Rides and Events Brimstone difficult trails?? July 28, 2015 We went to Windrock earlier this year and hit all the black trails….some were pretty challenging and we were able to complete them all. Wondering if Brimstone has any trails rivaling Windrocks?? We may plan to head their for the Camp RZR event.
