Something FishyFish spas are a fun experience, especially taking someone who has never been. Shenzhou First Hot Springs Resort has a nice fish spa, but also has a beer pool and a milk pool. Actually, it has dozens of different hot springs, including traditional relaxing ponds surrounded by beautiful rainforest scenery. Staff provide free tropical fruit to nibble on, and there's a full restaurant as well.
