Sanya Nanshan Treehouse
Why It’s Unique: Built into a stand of tamarind trees, the “Big Beach in the Sky” treehouse sleeps four in rustic accommodations steps away from the blue waters of the South China Sea. While the treehouse does have electricity, guests will have to walk 35 feet to a hot shower.
Access: Rope-and-plank suspension bridge.
What to Do: Visit the botanical gardens and temples of the adjacent 5,000-acre Nanshan Buddhism Cultural Theme Park, which includes a 354-foot statue of the Buddha Guanyin.
