Being reminded of my backpacker daysButterfly Valley is named because its home to over 100 species of butterflies. It is only accessible via boat or walking trail. It is virtually untouched by mass tourism and is basically a large campground at the bottom of a very step 1000+ foot valley. It has simple hut accommodations and tents with bedding. There are two well run restaurants and a little shop to buy the essentials you may have forgotten. I arrived without an overnight bag, decided to stay over and was just fine. The environment is very communal and social. There is plenty to drink so its possible to stay up all night by the bonfire and get to know the other travelers. It's great fun, but only for those who feel comfortable roughing it with dreaded hippies. You can also just hang for the day and return on the afternoon boat.
