Perfect spot for kayaking/birdwatching
One of my Texas relatives mentioned this area to me in regards to my birdwatching. Decided I had to make the trip as I do love birds and the water. Saw at least 40 bird species (probably more but I didn't always have my binoculars handy).
Kayaks are available for about $15-20. Several paddling trails will give you a scenic trip.
Facilities at campsite itself are primitive (vault toilets). The site we had was right on the beach, and I believe the other campsites were as well.
As with most of Texas, bring mosquito repellent or prepare to be covered in bites!
