Matthews/Winters is a good starting point for more than one trail. From the parking lot, go down the trail and over the bridge. Just after the bridge is the Villiage Walk loop, a short 1mi beginner loop that can be ridden in either direction. If you go straight (counter clockwise) in about .3mi you will come to the Red Rocks trail on the right, at this point you can either continue straight ahead to finish the Villiage Walk loop or head onto the Red Rocks trail. If you take the Village Walk loop back to the parking lot you can continue on to the Dakota Ridge trail by riding across Hwy 26 and up the hill on the other side. If you take the Red Rocks trail, at about 1mi you will come to the Morrison Slide trail alternate on the right. Morrison Slide is an alternate that reconnects with the Red Rocks trail in 1.2mi. You have a choice to continue straight on the Red Rocks trail and stick with less climbing or turn onto the Morrison Slide trail and go up several switchbacks to the "tabletop", the views here are great but there are some very rocky switchbacks on the downhill side awaiting you. At the bottom of the switchbacks the Morrison Slide trail re-connects with the Red Rocks trail at which point you can turn right and coninue on to the Ampitheatre and Dakota Ridge trail or turn left and take the Red Rocks trail back to the Villiage Walk trail and on to the parking lot. If you decided to pass the first Morrison Slide cutoff and continue straight on the Red Rocks trail for .8mi you can return by turning right onto the Morrison Slide trail and following it back in the reverse direction.
