Wenzhou Amusement Park is a family-oriented theme park on the southern side of the city. It is not the reason to come to Wenzhou, but it can be useful if you are travelling with children and need a straightforward break from temples, museums, and wetland walks.
Treat it as a half-day local outing. For most travellers, Jiangxin Island, the riverfront, and the Sanyang Wetlands are more distinctive Wenzhou experiences.
