Trail Hero 2020. This is the beautiful and scenic Triple 7 trail. This is one of the best 4x4 trails in Sand Hollow. We had a ton of fun as 9 year old Carter was able to run around and play and Jared drove a Jeep for the first time off road on a trail rated as an 8. Trail hero is a lot of fun, if you ever get the chance be sure to go if you can. Triple 7 trail. Jeep off-road. Bronco off-road. Sand Hollow off road. Extreme rock crawling. Jeeping.
