Nightlife on the island of Brač is laid back and restful – you'll get plenty of beauty sleep here, unless you hit the local bars early on then go for a moonlit swim.
In the centre of Bol, cocktail bar Varadero (Frane Radića 1; 021 635995) overlooking the harbour is the place to be seen – complete with straw umbrellas, DJ music and exotic cocktails, it's friendly and relaxed, gets incredibly busy in high season, and stays open till 2am. Another popular bar in Bol is Bolero (Put Zlatnog Rata bb), set amid pine trees overlooking the sea, on the promenade leading to Zlatni Rat beach. With lounge style furniture, chill-out electronic music and cocktails, it's a great spot for a sunset drink after the beach, or a waterside nightcap after dinner.
If you're staying in Postira, La Luna (Postira bb) serves drinks overlooking the fishing harbour till late.
