Absolutely try to take the Lake Danao tour with the floating house when in Ormoc. Located in a national park on a large, still pristine freshwater inland lake surrounded by jungle. You can swim all day and have meals delivered to you while you drink and admire the unspoiled beauty. Freshwater clams were the specialty but I found them pretty bad. There are some waterfalls in the park tough to get to but worth the hike. Yes, there are some small leeches in the lake but don't be a big baby if they get you like my wife was.
