A government-owned ferry connects the two islands, linking Lovely Bay on Acklins Island with Brown's on Crooked Island. It operates daily, about every hour from 9am to 4pm; the one-way fare is $5.
Once you arrive at Crooked Island, taxi service is available, but it's wise to advise your hotel in advance of your arrival -- they'll probably send a van to meet you.
