The last island that we visited from Dubrovnik was Mljet for its national park! (This was going to be the first out of the three national parks we planned to visit in Croatia!) By that morning, we had the whole routine down: walk down from our apartment to Old Town, take the bus from Old Town to Gruz Harbor, eat breakfast at a nearby cafe, and hop on a ferry. This time, we took the G&V Line ferry to Polace, Mljet.
Once we arrived, Clay and I purchased our NP tickets and rented a couple of bikes to get to Veliko Jezero, the bigger of the two saltwater lakes in Mljet. (Unfortunately, we didn't have enough time to check out Malo Jezero, the smaller lake, that day.) We ended up biking to the gift shop located at the edge of Veliko Jezero, where we parked our bikes and took a small boat to St. Mary (an island within the island!). On St. Mary, we visited a 12th century Benedictine Monastery and then spent the rest of the afternoon swimming in Veliko Jezero. We probably swam about 1/4 of the way around St. Mary. After our swim, we ate lunch at Restaurant Melita before we took the 5-minute boat ride back across the lake. The bike ride back involved some uphill and took us about 30 minutes. Back at Polace Harbor, we had some extra time to bike and walk around before our 4pm ferry back to Gruz Harbor.
I thought that Mljet National Park was definitely worth a day trip to visit! Clay and I actually realized that maybe we should have moved from Dubrovnik that morning and stayed a night on the island, which was very beautiful and green. The nature was breathtaking since most of it has been left untouched. Note for those thinking of visiting, the entry ticket for the NP comes with a bus ride that will get you close to the lake. Biking can be challenging with some up and down hill, especially on a hot day, but it's fun! As for the water around St. Mary, it is very clear, calm, and great for swimming -- just be mindful of the rocks along the edge.
Just capturing as I go.
