Toas island is located 2.5 kilometres (1.6 miles) to the south of San Carlos peninsula (western section of Maracaibo Lake sand-bar), and 5 kilometres (3.1 miles) east of San Rafael del Moján, a small town on the west coast of the lake.

There are the saline ponds called "El Toro" and "Aracho", a mine of sulphurous lignite, and several limestone caves which have been exploited since Spanish colonial times.

Also exploited by the Spanish are clay caves in the southern area, and a small copper mine.

El Toro (Zulia), a fishing village, is located on the island, which is also the capital of the Almirante Padilla Municipality.

The small town has also a church and various shops located in a typical Spanish square, the Plaza Bolivar.
