A town on the edge of a national park full of amazing mountains and enormous caves.
Central Backpackers Hostel: this hostel had a pool, it served brilliant food so we didn't eat anywhere else while staying there. They also organised cave/park tours straight from the hostel, and the coaches to and from the town. At night they put on some drinking games and directed us to which bars were good, so it felt like a good party when we were there.
Caves: the main attraction in the park is the vast number of impressive caves, that are filled with all sorts of formations, and could probably fit cathedrals inside them. The one I visited was Paradise Cave.
Another of them (Dark Cave) was less touristy and you had to get in via river: either zipline or boat. Then once you're inside there's pools of mud that you can bathe in, quite a therapeutic experience. The river also had some obstacle courses on/above, and slides/swings and ziplines to jump off. These tours were all organised from the hostel.
Duck Stop: there's a duck farm near to the town that allows visitors in to see the ducks. It sounds silly, but it's very fun, the ducks basically play with you while you feed them. Worth a visit because it's so funny.
