Suggested Seasons to visit: May-mid October Only, Thursday-Sunday, 6pm - 9pm

Site open for day use only.

From the intersection of TX 29 and US 87 in Mason, go south on US 87 for 1.2 miles to the intersection with FM 1723. Go south on FM 1723 for 2.3 miles to a Y-intersection. Take a right onto FM 2389 for 4.8 miles to James River Road. Continue on James River Road for 8.2 miles to Bat Cave Preserve. Note: just before reaching the preserve, you must cross the James River in your vehicle. River levels can be as low as a few inches in dry conditions and higher during wet seasons.

The cave is a bat preserve and is located 1,500 feet above the parking area. This small Nature Conservancy property houses 4 to 6 million Mexican Free-tailed Bats, the second largest colony in Texas. The cave is referred to as a maternity cave, as the females use the cave to bear and rear their young. In the fall, these bats migrate to Mexico. Woodland scrub in the rocky terrain is habitat for Painted Bunting, Canyon Wren, and Black-throated Sparrow.
