Most travellers, however, still rarely venture beyond the more famous islands – and a little exploration is all that is needed to take you to some lesser-known gems. Here are 20 of our favourites.
Ammouliani
Nestled between two prongs of the Halkidiki peninsula, this small island has great sandy beaches and is a welcome relief from some of the bigger resorts on the mainland. Most visitors are Greek and it retains an authentic atmosphere.

This small island consists of only three villages and a population of just over 1,000. Just across from popular Lefkada, it’s not usually considered a destination in its own right, and is mainly visited on day trips. Staying on the island means you can explore its many “hidden” coves at your leisure.

Antiparos
Paros is well known, but relatively few make it to the island opposite. For those in the know, including a fair few celebrities, Antiparos provides a relaxing haven in this often busy group of islands.

Schinoussa
With a population of around 250, this island rightly describes itself as a “small paradise” and the atmosphere is suitably chilled out. The only settlement is a one-kilometre walk above the little port, but most hotels will meet you off the ferry.

Tilos
Along with some of the larger Dodecanese, Tilos is greener and more lush than many Greek islands, and is renowned for its wildlife, from flowers to birds. Its gentle landscape rewards hiking, and it offers small villages and unexploited beaches.

Halki
Halki is one of those islands you fall for instantly. Arriving in its main town and port of Emborio, you immediately notice the many 19th-century mansions that bear testament to the island’s history as a thriving fishing and merchant capital. Its sleepy atmosphere makes exploring a delight.

Agistri
Only a short hop from Athens, this little island is to be avoided in high season (July and especially August, when all of Greece is on holiday), but in the quieter months is a fantastic place to visit, especially in combination with a city break in the capital. It is also not far from the famous ancient ruins of the Peloponnese.
