The Lokrum boat service - departure from Old Harbour every hour starting from 9am till 5pm. Return from Lokrum every hour starting from 9.15am till 17.15pm. Last return from Lokrum at 6pm. In case of bad weather condition, the boat does not operate.
Its very simple to reach Otok Lockrum as taxi boats leave from old harbuor of Dubrovnik every 30 minutes during summer and its only takes 10-15 minutes to sail there. Tickets were just 35 kumnar return (thats £3.50) in 2005. Keep your ticket too as it has a handy map on it. There is just one bay that the ship docks by - just near an old villa that is being restored.
Getting to Lokrum from Dubrovnik is easy, convenient and inexpensive.
Boats depart every hour during shoulder season and twice an hour during the summer from Dubrovnik's Old Port.
Return tickets can be purchased right at the port and cost 25 Kuna ( a little less than 5 US dollars). There is a small map of the island right on the ticket. The ride to the island is only about 10 to 15 minutes.
