If you’re looking for a one-of-a-kind shark encounter, visit Cornwall in May, as this popular English seaside destination hosts basking sharks from May to October.

May offers the best chance for calm seas and clear water to snorkel with basking sharks, long before the crowds of summer tourists arrive.

Growing to around 20 to 26 feet (6 to 8 m) and weighing up to 11,000 pounds (5,000 kg), these impressive sharks are a treat to swim with. If you don’t spot basking sharks, you’ll still have the chance to swim with playful gray seals and common dolphins. You can also watch Cornish seabirds and maybe even spot a mola mola.

After a day’s snorkeling and wildlife watching, recount your adventures over a traditional Cornish cream tea or tour some of the prettiest Cornish villages you’ll likely ever see.


May dive destinations

It’s the last month of the dry season in Tobago, with low visibility but plenty of manta rays flying about. It’s also a great time of year to go turtle spotting and watch Tobago’s turtles nesting on the beaches at night.

Bordered by the Atlantic and Caribbean Sea, a variety of currents wash Tobago, which adds up to plentiful marine life. There are over 400 species of fish and critters, plus nurse sharks, dolphins, turtles and numerous manta rays.

Tobago’s underwater landscape includes arches and caverns, and there is good drift diving as well. Dive guides typically take small groups, and it’s rare to see other dive boats, adding to the sense of peace as you drift along colorful reefs.

Kelleston Drain is a must-see Tobago dive highlight. This reef is home to the world’s largest documented brain coral — a staggering 10 feet (3 m) high by 16 feet (5 m) wide.
