Providenciales is filled with good snorkelling spots, but the best ones are arguably Bight Reef and Smith's Reef, both located in the central region of the island. You have good chances of spotting green turtles, southern brown stingrays and even nurse sharks. If you want to see nocturnal sea creatures like squid and octopus, you're free to do some night snorkelling (provided that you have the equipment for it).

The only active volcano in Continental Europe, Mount Vesuvius is a popular destination for excursions, and offers a stunning panorama over the Naples bay, as well as a thrilling opportunity to look inside its crater. Infamous because it destroyed Pompeii 2,000 years ago, Vesuvius is now carefully controlled by geologists. An interesting choice can be visiting it in the morning — it's only 20 minutes away from Naples — and then heading to the Pompeii archaeological site in the afternoon.

This legendary market will blow the mind of anyone who happens to have even a passing interest in seafood. The sheer variety of sea creatures sold here must be seen to be believed: apart from Korean favourites like crab and eel, there are the myriad types of fish and shellfish (try the 'kalguksu' noodles with clams, or 'bajirak'), plus essentially anything that can be extracted from the deep waters washing over Busan. Take a stroll around to gawk at the market's curiosities, such as the sea worm ('gaebul'), whose visual similarity to the male reproductive organ has earned it the apt nickname of 'penis fish'. Then, select the seafood that tickles your fancy and have it be cooked right then and there by one of the shops inside the market, many of which have a seating area in the second floor. Get all your seafood from a single vendor if you can, then proceed upstairs to be served your selection accompanied by sauces and side dishes (a few the latter can even be served on the house if you're in luck). Mind that a cooking charge applies, and the price on side dishes is listed per person. Given the upsurge in tourist numbers, prices at Jagalchi have reportedly gone up in recent years, leaving it for travellers who aren't exactly on a budget. Do not despair: most of what you'll see at the market is also served at nearly any seafood restaurant in town, and at a lower charge in some cases.
