In the western outskirts of Mumbai, the Kanheri Caves are laid in the middle of the Sanjay Gandhi National Park. Carved out of rock mountains and with a history that dates back to the first century BC, they are existing proof of the Buddhist influence on India. The surrounding forest features an area full of waterfalls and local flora.

The Blue Lagoon is without a doubt the most well-known geothermal spa in Iceland. The signature milky-blue water makes a stark contrast to the surrounding black lava fields and creeping grey moss. The spa is located in a lava field near Grindavík and is supplied by water used in the nearby Svartsengi geothermal power plant. The water temperature stays at 39°C year-round, snowfall or sunshine. Most visitors make the spa their first or last stop, since it's conveniently located only 15 minutes from the Keflavík International Airport (and around 30 minutes from the capital city). If you are buying a tour, it makes most sense to combine the spa visit with the Golden Circle day trip.

Höhenpark Killesberg is Stuttgart’s go-to green space when you want a break from the city buzz. It’s got a bit of everything: a 40-metre spiral tower with city views, a miniature train that loops through the park, and a petting zoo with goats, donkeys, and llamas. During the summer months, the outdoor pool and wave machine are a hit, and there’s plenty of space to picnic or wander through flower gardens.

A seemingly endless expanse of white powdery sand and clear turquoise water, Playa las Coloradas is another of Cayo Coco's best and most popular beaches, as well as being home to several hotels, including the Melia Cayo Coco, Hotel Pullman and Hotel Sol Cayo Coco.
