Isle of Mull
Scotland, United Kingdom
Best for: adventurers
One of the largest Scottish islands, Mull is an outdoorsy nirvana. Hire bikes in the main town of Tobermory or get involved in an e-bike cycling tour. Kayaking, bouldering, wild swimming and hiking are also popular pursuits, while others visit the island to climb up majestic Ben More, the only island Munro (that's Scottish for a mountain that's more than 3,000ft high) outside Skye. Mull is also a twitcher's paradise, home to the white-tailed eagle - the UK's largest bird of prey - as well as merlins, buzzards and hen harriers.
Stay: Camping is big on the island, and Pennygown Holiday Park has the best views as well as a small shop selling meat from their own farm. It's a good jumping-off point for adventures.
