Laguna has rugged terrain, with narrow plains near the shores of Laguna de Bay and mountainous ranges further inland. Laguna de Bay is the largest lake in the Philippines, and is named after the town of Bay. Laguna is also home to Mount Makiling, a dormant volcano near Los Banos reputed for its mystical properties. There are also a lot of hot springs near the Makiling area, especially in San Pablo. Another famous landmark in Laguna are the Pagsanjan Falls, in Cavinti. The water from the Pagsanjan Falls comes from the Bumbungan River. Mount Banahaw borders Laguna and Quezon, and is similarly considered to be a holy mountain like Makiling.
