Jared84 - 8/02/2017 4:33 AM Can I park at City Park during the week? The walk back from Rio Vista seems doable in gear, think Ill try this one soon. BillParker - 8/02/2017 9:22 AM If you mean Rio Vista Park you can. You can’t park on the university lot during the week without the proper sticker.

wuzaracer - 11/16/2016 11:07 AM I would like to ask if anyone can suggest where to enter and exit for a dive on the San Marcos River? My dive buddy and I are planning on leaving one vehicle at the exit to drive back. Any suggestions will be appreciated. Thanks. Greg BillParker - 11/16/2016 6:26 PM You can enter at Sewell Park (parking on weekends only) and exit at Rio Vista Park. From underwater you know you’re near the exit when you see the supports for the railroad bridge. wuzaracer - 11/16/2016 7:33 PM Thank you

BillParker - 1/31/2015 4:51 PM I went scuba diving here on 1/31/2015. Average viz: 41-50ft/12-15m. Water temp: 71-75°F/22-24°C. Great vis. I saw 100s of fish, acres of marine plants, and a few large turtles. I stuffed a large mesh bag completely full of trash during the dive. I won the divingrebels.org prize for picking up the most trash. This is my favorite Texas dive.

Water in the 70s year round makes a great place for an inland winter dive. Dive #1 (water falls): youtu.be/uoMcC6z35_8 Dive #2(drifting a mile down the river): youtu.be/X7d8IYyUyKw
