Although the weather is glorious, summer (late-June to August) can get very busy on the island, so we recommend spring (April to early-June) or autumn (September to early-October) when it is still warm enough to swim, and walkers and cyclists can enjoy the coastal paths in comfort. International flights are reduced during winter, which can make visiting trickier.
Although there are public buses and taxis, we'd recommend hiring a car as it’s by far the easiest way to get about. The roads are relatively quiet, and follow a simple fishbone system that makes them wonderfully easy to navigate - there's a main road running east to west, and then smaller roads leading off it towards the coast. Driving also allows you to explore the many pretty beaches and more rural areas, which are highlights of the island.
