After meeting your guide and short briefing and intro, you will walk through the old town to reach the old town port. Here your adventure starts by boarding the island boat for a transfer to Lokrum.
Upon arrival, you will be given a brief orientation to what to do and where to go and then you will have approximately 4 hours of free time to enjoy the island on your own. You can use your time walking through the Botanical Gardens that were planted in the 19th century or check out the ruins of the medieval Benedictine Monastery.
If you wish, you can take a guided tour in the islands (not included) to make the most of your visit.
Once you are done exploring the island, follow the instructions of your guide to catch the island boat back to Dubrovnik's old town.
