Adventure park with obstacles (suspended bridges, wires, ladders etc) suspended 1-2m over the creek. There's no zip wire. It takes 30-40 min to finish the whole route. Obstacles range from very easy to very difficult, requiring a lot of strength. Children have to be at least 120cm tall to be able to participate. There's also a playground for kids with zorbing, swings and a jungle gym.
应星楼
Beautiful building with a focus on astronomy. There is a small rotating exhibition on the ground floor and the 2nd and 3rd stories contain an exhibition about Chinese astrology. Climb up further and there's some kind of star show that doesn't run very often and on the very top floor you'll find a small temple with fantastic views of the city and waterfront.

Large museum with lots of different exhibitions, including history, animal life, the 3 treasures of Lishui (pottery, sword-making and stone-carving). Plan to spend a couple hours here. Small gift shop.

The Old Pagoda 厦河塔
A Ming Dynasty pagoda in pretty good condition. The best time to visit is sunset, when one can take full advantage of the western-facing view of the city and its mountains. Make sure to wander around a little, and check out the connected temple, which can be accessed through a small shrine half built into a rock, off the right of the path up to the temple.
