Windrock trail system is much larger with 250+ miles of trails. The trails are all maintained at Wayehutta. I haven't been to windrock in a few years since its about a 2:30 drive for me over I-40. Windrock is a great place to ride but I haven't been since I purchased a RZR. The day fee at Wayehutta $5 per day with a self service pay box or $30 for year pass. They don't allow camping but there is a covered picnic area. It has similar logging road type trails as windrock as well as "most difficult trails". Trails 2, 11 are wide fast trails. Trail 1 is the main loop and offers a mix of everthing. Trail 7 7a has deep rut section and two steep switchbacks. Trail 6 and 9 have rock crawling areas. I'm 20 min away from Wayehutta so for me is my normal weekend destination and sometimes during the week. Windrock is certainly larger trail system.
