Haikou has many temples. The most famous is Five Officials Temple (五公祠 Wǔ gōng cí). This is a fairly well known place on the tourist route, ticket price 20 RMB.
There are many small interesting temples that are generally not visited by tourists and do not have an entrance fee. These are real temples that are still part of the local communities. Wander off the main roads into the small hutong back alleys and your bound to find a few. If you do not like tourist places these temples may be more interesting than Five Officials Temple.

This is not actually a temple but an ancient college. Qiongtai College is credited with bringing modern academic study to Hainan from elsewhere in China. The interior has been restored and in some ways looks similar to a temple. Part of the college space is used as an art gallery for locally inspired art (Aug 2010). There are small good painting and photos on display.
Entrance fee: 5 RMB
