This trail offers five loops of varying lengths and difficulties. The terrain rolls up and down small hills in Tyler State Park. The ground is very sandy not to mention the roots and rocky sections. There are some short steep sections. EZ, the first loop is short and makes for a good warm up. Loop A is also short. Loop B begins a the end of loop A. Loop B is the longest loop. It rolls up and down through a low lying area but the sandy soil provides more then enough drainage. Bridges have been put in over the major water crossings. About half way through Loop B you turn onto Loop C, which has a bit more climbing and is a bit tighter of a trail. The rolls are steeper, and there are a few more roots. Halfway through Loop C you turn onto the last loop, Loop D. This loop climbs the most and has some really fun technical sections. Loop D ends at the portion of Loop C that you haven't ridden. At this point you are rolling down hill, back to the parking lot. You then hit the portion of Loop B that you haven't ridden, and that takes you the rest of the way back to the parking lot.
How to get there:
From Tyler or I-20 (from Dallas about 1.5hrs east), take FM14 N. to Park Rd 16, which enters the park. Drive the park road counter clockwise to the Blackjack campground. Park there. The trail loops start and end here.
An hour and a half drive from Dallas.
