The Bawah Reserve, Riau Archipelago, Indonesia

To say that the Bawah Reserve is located in a remote area is a bit of an understatement. This retreat can be found in the Riau Archipelago 150 miles off of Singapore. It includes 35 bungalows and suites.
Situated between Borneo and Malaysia, this unique reclusive reserve is accessible only via private seaplane. Explore the three lagoons and 13 beaches on the six islands. Go bird-watching on the lush green nature trails, kayaking, hiking, paddle boarding, sailing, swimming and discover the marine life under the azure blue sea.
The Casa da Árvore At UXUA, Bahia, Brazil

Staying in this one-bedroom treehouse ensconced amidst the leafy palms of Trancoso’s UXUA Casa Hotel & Spa might make you feel just like a sloth. Here the rooms are divided into a trio of levels that are supported by their own set of wooden stilts. Each has one deck that includes a personal outdoor hot tub.
The quirky treehouse is constructed from organic materials from Bahia including vines, palm fibers, and reclaimed wood. So be a kid again with the wooden swing then soak away your soreness in the hot tub.
