One of Houston's best-kept secrets emerges nightly at sunset from underneath the Waugh Drive Bridge near Buffalo Bayou -- a colony of about 300,000 Mexican free-tailed bats! They draw a regular crowd of onlookers. Join them from the sidewalk of the Waugh Drive Bridge or from the north bayou bank, east of the bridge in Buffalo Bayou Park. You can park at Spotts Park or along Allen Parkway.
