Lanxi's Liudongshan Underground River Scenic Area has become a popular destination in Jinhua, Zhejiang province, drawing long lines of visitors.

The cave maintains a constant temperature of 18 C, serving as a sort of "natural air-conditioner", and offers boat rides through caves as well as stunning light shows. The new slide facility, which shortens a 15-minute walk to just three minutes, has made the area even more popular.

This summer, the scenic area is offering free admission to full-time university students, graduate students, and doctoral students.

Water activities are a major part of summer tourism in Lanxi. Yuelongshan Grand Canyon rafting, which opened on June 1, attracts visitors from all over.

The rafting course features a 160-meter drop and takes about 150 minutes to complete, with unique elements like water gun battle zones and a time tunnel.

The Bailushan Water Park, which opened on July 6, offers attractions like a wave pool, deep-sea tornado, and high-speed slides, providing exciting water experiences for visitors.

Lanxi also offers night tours to beat the heat. Boat rides offer breathtaking night views of the Lanjiang River and pass by landmarks like the Lanjiang Bridge and Zhongzhou Park.
