Good spot on the Rio but doesn't give you much reward for the heat and exposure to the sun. Try TA 2 back up the road for good wind, epic sunsets, and a near 360 of the surrounding mountains.
March, 2023. It is on the river! We spent most of our time waterside on the rocky bank. The campsite itself is baby powder sand 2” deep. It is really nice to drive down here for easy access to the river but I would have rather camped at TA2 on the rocks and visited TA4. We stayed during march. Its always warmer “down by the river” the forecast said 84 but we were getting temps of 95 at camp. This is a commonly used river crossing for horses and cattle.
This is about as secluded as it gets in the park. Right off the Rio. You can take the black gap off road trail to get here, which is pretty fun. Very tame for its rating. Easy access to the mariscal rim trail, which is super fun.
