This place was definitely worth the trip. Yalong Bay is a little out of the way if you're in any other area in Sanya, but the Tropical Paradise Forest is gorgeous. It's lush and green and there's lots to see. It's pricey - your ticket includes a bus ticket that takes you to the three areas in the Park. Each area has something different to offer. You might have to queue for the rope bridge, but the Lover's Walk takes you to an equally beautiful view of the city and forest. Finally, the Glass walk is the last stop but it's quite pricey and full of people, so I skipped it. It's a great place for taking amazing photos and looking at nature but you could wind up spending a ton of money. Worth the trip, though!
