This is a network of trail that can be ridden in any direction. This one I believe provides the most fun! Starting up the trail proceed past the sign for Wally's World (this is where you will exit) to Poison Creek Trail. Take a right on Poison creek and continue until you come to a junction (about 2.17 on this segment). Poison is uphill but completely rideable. At the junction take the trail for Tusky Ridge (you will be back here so go ahead and look around). Tusky is downhill riding through some awesome Aspen stands. At the next junction (about 2.15) take a right onto Squaw creek. It is mostly uphill for another 1.6 but fairly mellow back to the junction with Tusky ridge. This time at the junction take a left unto Wally's World. There is a little bit more uphill but you are rewarded with huge views before you bomb down back to the car. When you hit your next junction take a left back to the car.
Review: Trial is a great mellow ride through alot of Aspen trees. All of the uphill on the lower section is moderate but enough to provide fun downhill on Tusky and Wally's World trails. You can make it an epic day and add Big Munger if you have the time.
