Who it suits and why

Best for travellers who want charm without crowds. These islands suit those who like small, pretty villages, a few excellent tavernas, and beaches that are quiet even in high summer. It’s ideal if you prefer a relaxed, local feel over resorts and organised entertainment.

Less suited to those who want a lot on offer. If you want five-star hotels, beach clubs, shopping streets, or a full programme of boat trips and guided tours, a larger and more well-known island will give you far more choice.

What to keep in mind

Hidden gems stay hidden because they are harder to reach. Most have no international airport and rely on ferries from Athens or a hub island, with sailing times of 4 to 10 hours. In shoulder season and winter, UK direct flights stop completely and even domestic connections reduce.

Facilities are limited. Accommodation is often small guesthouses and studios rather than serviced hotels, and key services like ATMs, pharmacies and petrol stations may only be in the port town and keep short hours. You will usually need your own transport, and beaches are often unorganised with no sunbeds or bars.
