The Eckert James River Bat Cave Preserve is home to one of the largest Mexican free-tailed bat colonies in the world, offering seasonal viewing opportunities.
The Eckert James River Bat Cave Preserve protects a critical maternal colony of Mexican free-tailed bats. The site’s history is tied to the Eckert family, who purchased the land in 1907 and mined bat guano for fertilizer. In 1990, the family donated the cave to The Nature Conservancy to ensure permanent protection for the bats, with the condition that the land remain open to the public for education and observation.
The preserve is open Thursday through Sunday evenings from late May to early September. Visitors should call the bat hotline at 325-347-5970 before visiting to confirm the event start time, as bats emerge at varying times, and to check for weather or river flooding closures.
The preserve is a true wilderness area. There is no electricity, restrooms, water, or food available on site. Visitors should come prepared for a rustic experience and bring any necessary supplies with them.
The cave is located about 500 yards from the parking area. It is reached by a trail that leads over a slight incline. This trail is not wheelchair accessible, though benches are provided for seating near the cave entrance.
