Iceland tour

Sip on strawberry champagne as you soak in the milky aquamarine waters of the Blue Lagoon. This geothermal spa is a large hot pool which is naturally heated and surrounded by lava fields dotted with black volcanic boulders. It is the perfect activity come rain, shine or snow, and there is a swim-up bar where you can purchase healthy green spinach smoothies or miniature bottles of fizz. The centre also offers skin enhancing treatments, including algae face masks, a volcanic rock scrub or an in-water massage. The natural spa costs £29-£141 depending what package you go for but you can easily stay there all day as they have a selection of eateries including a pool-side cafe and the more extravagant Lava restaurant. The sushi in Blue Cafe is beautifully fresh, although quite pricey (but then everything in Iceland is) and the floor-to-ceiling windows offer an amazing view over the lagoon. This really is a once in a lifetime opportunity as the Silfra in the Thingvellir National Park is the only place in the world where you can swim between two tectonic plates. The plates are pulling apart at a rate of about 1inch a year and the crystal clear glacier water creates some of the best snorkeling and diving in the world, with visibility of around 120m. Although there is no wildlife to be seen, swimming along the great gap between the Eurasian and American tectonic plates is a pretty surreal experience and one defiantly not to be missed. Also if you are worried about the cold don't be - the water temperature varies between 2-4 degrees celsius during the year but your guide will give you appropriate attire to keep the cold out, including a onesie made of sleeping bag material and a dry suit. The only things that may get cold are your hands and cheeks, but you are only in the water for around 30 minutes, after which you're given a mug of hot chocolate to warm your frosty fingers.
