Talim Island is located at the center of the Laguna de Bay lake under the municipality of Binangonan on the western side and the municipality of Cardona on the eastern side in the province of Rizal. The island is rich in bamboo grass, with which islanders make different types of furniture such as bamboo sofas, cabinets, tables, chairs and a lot more. It is the main source of their living, while fishing on the lake is only secondary.
Two parishes are located in the island. Santo Domingo Parish is located at Janosa, Binangonan, and Our Lady of Lourdes Parish at Navotas, Cardona.
One famous feature of Talim Island are the "Bundok ng Susong Dalaga" (Maiden's breast mountains) - two huge mounds of conical hills resembling the female breast, which are the highest peaks of the island. These two hills are among the more famous of several hills in the Tagalog regions who share the same name, because local folks of old often named identical conical hills as such. This feature is best observed from neighboring Mount Sembrano across the lake.
The island consist of 26 barangays, 17 from Binangonan and 9 from Cardona.
