Fiji is a fairly male-dominated society, but it is unlikely that solo women travellers will experience any difficulties as a result.
If you’re travelling alone, you may experience whistles and stares but you’re unlikely to feel threatened. Nevertheless, some men will assume lone females are fair game and several female readers have complained of being harassed or ripped off, particularly in touristy areas.
On rare occasions lone women have been harassed and even attacked on mainland beaches and forest trails. We haven’t heard of any incidents on the small outlying islands, but exercise caution before visiting a secluded spot by yourself.
Generally speaking, though, female travellers will find Fijian men friendly and helpful.
