Laos nightlife has had quite a paradoxical character: From the extremes of the opium culture that infiltrated the country during the late sixties and early seventies, to the enforced curfew into the late seventies and beyond. Now, perhaps it has it found its equilibrium as the 'sleepy town' of the region yet with Southeast Asia's best beer.
The odd 'happy shake' can still be found in Vang Vieng, but the rest of the country has cleaned up its act and the most outrageous nightlife you will get in Laos is in Vientiane where a handful of nightclubs stay open past midnight. While the country is packed with fun, it is not the place to come if you want a Patong-style holiday.
Lazy riverside bars, quaint wine drinking venues and a handful of nightclubs sounds about right for the range of nightlife in Laos. Alternatively, internet cafes in the bigger cities are usually open until late. The charm of the sleepy town can also lend itself to relaxing nights best spent rekindling your appreciation of nature.
