Birding – Enjoy world class birding in this popular birding spot. Specialties include green kingfisher, painted bunting, Audubon’s oriole.  You can check out up to the minute sightings here online at ebird.org.

Fishing – Fishing is allowed in designated areas only (you must must have a license and follow all State laws).  There are 8 or so spots to fish, clearly marked with signage and mono-filament recycle container.  The fishing is peaceful, but casting can be a challenge with lots of branches and roots to catch.

Picnic – The Natural Area has one large pavilion with 6 picnic tables, a drinking fountain, and pretty big BBQ grill.  Reservations are made online at San Antonio Parks Reservation System or at Parks and Recreation Ron Darner headquarters located at 5800 Old Highway 90 West, San Antonio. You need to bring your own firewood or charcoal as gathering firewood in the park is prohibited. Electricity is available upon request, but bring your own extension cord and power strip. No smoking, loud music, jumping castles, skateboards, or piñatas are allowed in the pavilion/park.

Boating – Canoeing and kayaking is also allowed, but you must use the single designated launch/recovery site provided in the park. This means you must either find a take-out site outside of the park OR paddle back upstream and take-out in the same designated spot.  For paddling, just know that we have seen very large trees all the way across the water that can block through passage.

NO horseback riding, skateboarding, or motorized vehicles (except wheelchairs) allowed on trails. NO Swimming or water contact allowed.
