Get picked up at your hotel in the morning and hop in the air-conditioned vehicle to start the island excursion. On your way to the port of Gruž, learn from your guide about the history and culture of the places you'll be visiting that day. Once at the port, climb aboard a catamaran and get ready to sail the Adriatic with your guide and group. Drink in the incredible views and the natural beauty of the area.
Hop off the boat at Polace, located on the northern end of Mljet, and take a scenic ride to Pristanište. Drive through Mljet National Park and stroll along the hiking trails, flanked by verdant shrubbery and trees. Learn about the history of the islands -- that the name comes from the Greek word for 'honey,' or that it was first mentioned in records as far back at the 6th century BC. Hop in another boat to cruise around two inland salt-water lakes, Malo Jezero and Veliko Jezero and enjoy more pristine natural scenery.
After the boat ride around the lakes, transfer to a second boat for a trip to the diminutive island of St. Mary. Explore the small isle with your guide and discover the incredible 800-year-old Benedictine monastery. Spend some free time on the island, indulging in a delicious Dalmatian lunch (at own expense), take a dip in the refreshing Adriatic waters or go on a leisurely stroll around the island before heading back to Dubrovnik and getting dropped off at your hotel in the late afternoon.
