Fuxing Island sits adrift on a bend in the Huangpu River, a narrow strip of dockyards and decrepitude. It’s perhaps a destination only for serious history buffs, since the sole attraction here is the villa where Cheng Kai Shek spent his last night in Shanghai before fleeing to Taiwan in 1949.
The villa is occasionally, if unpredictably, open for public viewing, but you can always peer in through the windows from the adjacent Fuxing Island Park. Though the rest of the island bears the marks of heavy industry, the park itself is actually rather nice; shaded by ancient camphor trees and delightfully well-kept.
Otherwise the island is interesting only for how much unlike the rest of the city it is; empty of people, more rust than regeneration. Plans are afoot to develop the island into some kind of eco-attraction, but for now visitors remain rare.
If you’ve seen the major sights and fancy picking a target for some more serious urban exploration, it’s worth considering.
