The Sansom Park Trail is a mountain biking trail about 20 min from downtown Fort Worth, TX in Marion Sansom Park, on Lake Worth. 

I've been there several times and have not ever had any issues with bikers running into me, as I go there to hike. If you like trail-running, this place is great too. The ascents and descents create a very moderate to difficult trail for running. 

It is 11 miles, in and out, and you get to enjoy a waterfall at the lowest point of the trail! 

The elevation gain is about 2,000 feet and the view up there is GREAT. 

  I go here for some intense trail-running, as well as a moderate hike with lots of uphills. The trail is heavily shaded by diverse trees and tall underbrush. The fall foliage here is also great, although most of it has dropped by now.

 The pool that the waterfall flows into is shaded and encompassed by a lot of rock; some of it is even climbable if you dare. 

If you use the All Trails app, you can find the ratings, reviews and pictures about the trail here.

Overall, this is probably one of my favorite places to hike near my house. Definitely a fun spot!
