Hoping on what Ocean said, it's worth a visit, but if one wasn't going to the surrounding areas as well, I think I might as just visit the ocean park at Dounan, about the same, and cheaper.

Right now price is 230 per adult, add 30 yuan and it's year round pass.

kids about 150, plus 30.
kids under 110 cm free.

The biggest, and longest show is the circus, runs about an hour.

Everything Ocean stated about the park and shows is accurate.

Parking is 10 yuan and can stay overnight if adventurous?

Toilets and water close.
Food stalls and restaurants, but close at park closing time at 6 pm.

Nothing is in walking distance to the park, but there is a local market every morning, we went there to stock up on food and eat breakfast.

I think the biggest benefit of this place, if one is considering the annual pass, is the other local places to visit.

There is a large farm with a play area nearby, camping, and tiny home and trailer rentals.
Another parking lot to stay for free.

Shilin Forest and Jiuxiang Cave are close, with another large lake nearby and other farms.

This place is worth a visit although it's some way out of town and ticket prices are 200+ RMB per adult (the annual family pass is only 900 RMB though).

In "Ocean Park" you have a large aquarium, and dolphin/seal/beluga whale shows. The "Snow Park" there is huge indoor refrigerated building with various ice slides, aerial walkways, skiing, skating, ice sculptures etc. In addition the theme park has funfair rides and a circus (note: inc some animal performances). These are all part of the entrance fee. You could easily spend a whole day here or two days including travel from Kunming.
