The only way to reach Lokrum is by boat, and it doesn’t take long.
The most common option is the official shuttle ferry departing from Porporela pier (near the Old Town port). The ride takes around 10 minutes, and boats run every 30–60 minutes during the season (usually April to October). Tickets include the entrance fee to the nature reserve.
You can buy tickets on the spot at the pier or online. In high season (July–August), it’s a good idea to arrive early or buy tickets ahead to avoid lines.
Alternative: if you want a more private option, some local kayak tours also stop at Lokrum as part of a longer route, but you can’t dock or explore the island freely without paying the entrance fee.
