Cruise along the coast south of Dubrovnik in a speedy catamaran and stop along the way to swim in the turquoise sea and explore two lesser-known, less-bustling villages. As you will discover at Betina Cave, a somewhat secluded spot that is only accessible by sea, the water is refreshing as well as beautiful. You will have time for a quick dip and a mimosa before cruising to Mlini, a teeny village known for its pebble beaches and shallow, crystal-clear water. Although you might enjoy nothing more than a swim and leisurely stroll along the seaside promenade, the quaint downtown of Mlini is also well worth a look. Nearby Cavtat also has a lovely town center, which the guide will show you as an introduction to this little haven perched on a wooded peninsula. During free time that follows, you might shop, dine on your own or simply meander about the gorgeous setting.
