That's one of the best things ever done. The instructors are great and experienced, deal well with people who are scared. Visit the park and you will have the best memories from your trip!
The park is great but the swing is awesome! The first step is scary but the staff helps you overcome your fear. The equipment is professional and new, nothing can happen to it. If I'm back to Krabi I'll definitely do it again!
You have to do this if you come to Myanmar! The balloons go from many spots so first walk around and ask, the prices and times differ too so just choose whatever suits you. Whatever you pay though you won't regret.
