The region of south Cotabato in Mindanao, several hours' journey from Davao City, is for those who are courageous enough to seek 'off the beaten track' eco-adventures. Lake Sebu, near the village of Suralla, is surrounded by rolling hills and forested mountains; and is home to the T'boli, a highland tribe famous for their colourful costumes, intricate beadwork, woven work and brass ornaments, as well as the Tasadays, a cave-dwelling people. The area abounds with waterfalls, natural caves and springs.
