The best way to spot the dolphins and whales that frolic in the waters surrounding Tenerife is on a cruise. And this three-hour trip by catamaran to La Caleta does just that, and even throws in a refreshing swim before you head back to the port. Cast off on this cruise around Costa Adeje, and you'll enjoy a different perspective on the dramatic terrain of the island. While sunning yourself and feeling a cool breeze wash over you, your captain will sail into waters known for hosting pods of dolphins and whales. With luck, you'll get to spot these magnificent creatures in their natural habitat. Over three hours, you'll make waves around La Caleta, keeping your eyes peeled for signs of activity. What's more, you'll learn all about their habits, migration and food, and have time to contemplate their majestic beauty before enjoying a swim of your own. Then it'll be time to head back to Porto Colon while soaking up the sun.
