Reimers Ranch is one of the best mountain biking destinations in Central Texas. Unlike most other trail systems, Reimers Ranch trails are one-way and mountain-bike only, so you don't have to worry about running into a hiker, kid, dog, horse, or mountain bike coming the wrong way. Also, there's a wide variety of terrain and obstacles. The beginner loop is comparable to the Slaughter Creek Trail on the WQPL land, while the advanced trail has a lot more narrow spots, ledges, and interesting terrain.
There is some shade out on the trails, but there are a lot of sunny parts. Bring sunscreen and more water than you think you will need - there is no running water at the park and no convenient place to get more, either.
After the ride, hike down Reimers canyon to the Pedernales River for a swim. There aren't any shower facilities at Reimers, so otherwise you're going to be stinky and dusty.
If it hasn't rained in a while, the trails will be sandy in places, so watch out for fishtailing.
There are four different trail loops to follow at Reimers, but they share trail, so there is probably about 20 miles of mountain biking trail out there. You decide which one to follow when you are on the trail, and they are well signed, except at the very first intersection where left is easy, right is harder.
