The small town of Vohémar lies on the coast and has beautiful, if wild, beaches. Swimming is not usually possible along this coast because of strong currents, but Vohémar is protected by a reef. Ask locals where it's safe to swim. The town has a couple of banks on the main road.
Vohémar is a good place to stay if you want to visit the Loky Manambato Protected Area in Daraina. Cheapest is Hôtel Sol-y-Mar, a row of ramshackle bungalows on a beautiful beach. Also in a stunning location is the Baie d'Iharana Hôtel.
