Lo De Marcos' biggest draw is obvious- It is blessed with a long, wide stretch of near-perfect, and almost completely empty, beach. There is a river outflow on the north end of the beach near the Tlaquepaque RV park and resort, and tidal pools at the south end. Humpback whales are commonly seen off of the beach. Lo De Marcos is built around a central natural wetland, where turtles, waterfowl, and other wildlife can be spotted. Iguanas are not uncommon.
There are festivals several times a year, including independence day and Semana Santa Easter week. On these holidays and long weekends, the beach swells with tourists from inland.
