The 2nd Mesa is generally fast and smooth riding. There are the occasional sand traps to deal with but they tend to be quite short. There are some fun sections riding near the mesa edge on the southwestern side of the loop, while the northern side has some nice rock features, exposed bedrock and steps.
This is a great option to make rides longer from either the 3rd or 1st Mesa's. Trail Junctions #6 and #5 are at either end of this loop.
