Volunteers from BCI and the Texas Nature Conservancy (TNC)
have been working hard since February to prepare the Eckert James
River Bat Cave for visitors. The cave, which is summer home to
approximately four million Mexican free-tailed bats, is one of
the top 10 maternity sites known for the species. Located in the
Texas Hill Country near Mason, the cave was purchased by the
Texas Nature Conservancy last year in a cooperative venture with
In addition to assisting with management of the cave, BCI is
providing interpretive services in the form of a three-panel
on-site exhibit that describes the history of the cave, the bats,
and the emergence.
Teams of BCI and TNC staff and members volunteered several
months of Saturdays to clear brush and rocks for a road, a
parking lot, and a trail to the cave. Braving both cold and heat,
drizzle, scrapes and cuts, and frequent run-ins with prickly pear
cactus, volunteers also laid railroad ties for seating and built
a rock wall barrier to prevent visitors from interfering with the
The site is accessible by regular passenger car, but be
prepared to drive several miles down a dirt road and ford at
least one shallow river. Visitors will be richly rewarded; the
bat flight at this cave is among the most spectacular in the
United States. Nearby Mason residents have been enjoying it for
years and are proud to share it with visitors.
The cave is open for visitation between May 1 and October 31.
You can obtain directions by calling Sharon Reynolds at the Texas
Nature Conservancy (512/224-8774) or write to TNC, P.O. Box 1440,
San Antonio, TX 78295. Interpretive programs will be given
periodically throughout the summer, and an intern will be present
Wednesdays through Sunday to answer questions.
