Zakynthos, or Zante, has shrugged off its reputation as a destination for lads on tour (as long as you avoid Lagana and the built-up south coast) by rebranding itself as Greece's greenest island. It's not just the emerald hills sliding into the electric blue Ionian: much of the south coast is a nature reserve where endangered loggerhead turtles hatch in the sand. The turtle beaches are off limits, but there are countless coves in every hue of green and blue. Favourites are tiny Xigia, with its bubbling underwater springs, and craggy Porto Limnionas, with sunbeds wedged between the rocks and palm-frond umbrellas positioned between the pine trees. Skinari is the starting point for boat trips to the most famous landmarks, the Blue Caves and Shipwreck Beach, where a rusting liner leans into the chalky cliffs. From Keri, you can cast away for Marathonisi island, another turtle sanctuary.
Apart from a boat trip to the smouldering crater of Nea Kameni and hot springs at Palia Kameni, there's not much to do but gaze at the mesmerising views from your suite, dangling on the edge of the caldera. The best hotels in Santorini are concentrated in Oia, but the inland village of Pyrgos is up-and-coming. Go for a twilight Bellini at Franco's or a cocktail at newcomer Botargo, with views that will leave you light-headed, followed by dinner at Selene, a pioneer of new Cycladic cuisine.
The almighty church has kept nightlife in check. If you must see and be seen, head to quietly glamorous Astivi or Stoa bar, on miniature Agia Lesvias square, in Hora. Beach life is generally languid and low-key; Psili Ammos and Livadi Geranou are our favourite hideouts. Dinner reservations are essential at Benetos, for Med-Asian fusion on an organic farm, and Lambi for grilled fish on a purple pebble beach.
