Near San Antonio. Hwy 35 and Hwy 10 both run into San Antonio. So if you are coming from out of town on one of those Highway's take Loop 410 west and follow it around to exit 11 (Ingram Road) and go outside the loop. Go to the first light (Ingram Park Mall - on your right), turn left (yes it's also called Ingram Road) and go straight thru the next light. As you past that light you will cross a bridge and on your right you will see a paved entrance (Do not take this one) just keep going to the very next low water crossing (entrance on your right) and you are at the beginning of the Den. The trails go back for approx. 3 miles and there are many obstacles to try your vehicle on from hills, to rocks, ledges, mud holes and just riverbed rock. Continue on the trail/riverbed and you will come to a bridge (Grissom Road) you can exit here and get gas and snacks. The Grissom side is a very wide rocky section that is fun to play on and get all flexy on. There are no set trails to stay on, so just try all the rocks out and enjoy

It's best to go with someone who knows the area, especially if it has just rained. There are some deep water holes that will swallow you up.
