Nearby Bracken Cave hosts around 15 million Mexican free-tailed bats in summer, the largest known mammal colony on Earth.
Best timeMarch – May for breeding birds, June – August for bat emergences.

Dos & don'ts
Local etiquette that keeps wildlife wild.
Do
- Visit Bracken Cave at dusk (Aug–Sept) for 15M bats.
- Support Balcones Canyonlands NWR habitat purchases.
- Keep distance — use zoom or binoculars, never bait animals closer.
- Stay on marked trails to avoid trampling nests, burrows and plants.
Don't
- Don't clear cedar (juniper) between March and July.
- Don't take home caddisfly-case rocks from clear rivers.
- Never feed wildlife — human food changes behaviour and shortens lives.
- Don't share exact locations of nests, dens or rare species online.
