Mindoro Island, Philippines, offers jungle, mountains, coral reefs and interesting tribal villages.
The best place for diving is around Puerto Galera, on the northern coast. That area has exceptionally clear water, pristine white sand, coral beaches and low-cost accommodations, though there are plans to develop larger resorts.
If time permits, hire a boat guide to take you around the island.
Inquire in the towns of Mansalay and San Jose (in the south) about visiting tribal villages in surrounding areas. The eastern part of Mindoro can be reached by air, and western Mindoro is reached by ferry.
Mindoro Island is 100 mi/160 km south of Manila.
