This is the northern-most tip of Matagorda Island. It sits at the nexus of the Gulf of Mexico and Matagorda Bay at Pass Cavallo, where the French explorer La Salle made his first unfortunate landing in the New World. The pass used to be significantly deeper, but is slowly closing due to tidal changes. The current is still very strong here, and a lot of sea life passes through. There is flat, shallow water in the lagoon heading south towards Sunday Beach, bump and jump to the northwest in Matagorda Bay where the gulf tides come in, and if you are brave you can walk to the Gulf side where intense wave action can be found (advanced sailors only). From the map you'll notice - the beach curves around from facing southeast to northeast. This means on south or southeast days it is not impossible to get out. If you have any trouble getting blown out away from the shore the other side of the pass is not far. Lots of dolphins and sharks have been spotted here but don't worry - wade fisherman come here all the time with no reported attacks. Camping is allowed. This point is a great place to sail all day, fish, and watch dolphins at sunset.
Someone who is familiar with these waters is recommended to shuttle new comers out by boat. There are many places where even seasoned boaters run aground. The point is on the way to Sunday Beach (well known by all the locals or regular tourists) directly south of the ruined coast guard station at Coast Guard Cut.
