Twin Lakes - adventure in the rain forest

The Twin Lake are crater lakes 900 meters above sea level on South Negros Island. Surrounded by virgin forest, it is one the most beautiful places to visit in the Visaya region. We will spend the night in tents just beside the lake. We'll cross the lake by native canoe to reach the campsite - an unforgettable ride. Challenging trails lead along steep valleys, past hidden waterfalls, and through local villages seldom visited. Lots of wild life, like eagles, monkeys and other life can be observed there. The vegetation Including an incredible variety of orchids you may never have seen before.
