Palau

The Republic of Palau is scenically magical. For such a tiny area of land, it packs a big punch. It's hard not to be overwhelmed by its extraordinary array of natural wonders: this is an archipelago of about 200 largely pristine limestone and volcanic islands, blanketed in emerald forest, surrounded by a shimmering turquoise lagoon. Unsurprisingly, diving is the number-one activity here, with truly world-class dive sites. Divers swear by Palau's exciting seascape, fascinating wrecks and stunningly diverse marine life – it's not dubbed 'the underwater Serengeti' for nothing.

When the underwater wonders have finished working their magic on you, there are other adventure options. Kayaking, snorkelling and off-road driving are fabulous, with the added appeal of fantastic settings. And for history buffs there are plenty of WWII relics scattered in the jungle, as well as a handful of well-organised museums in Koror, Palau's largest town.
