This volcanic stunner gets all the hype, but with overtourism taxes kicking in harder across popular spots like it in 2025, hopping to lesser-known islands is the smart move for 2026.

I’ve rounded up some fave under-the-radar gems based on what’s buzzing right now—think volcanic beaches, medieval villages, and that slow island rhythm. Ferries are your best bud here, with improved routes making hops easier, but book early for peak summer. Whether you’re chasing hidden coves or cultural kicks, these spots deliver without the chaos. Let’s set sail!
1. Milos: Volcanic Beaches and Lunar Landscapes

Think Sarakiniko’s moon-like white cliffs or Firopotamos for a pebbly dip in turquoise waters. It’s super hoppable from Athens with direct flights, and in 2026, with its rising star status but still fewer crowds, eco-tours are popping up to explore the island’s mining history sustainably. Rent a scooter to zip between spots like the catacombs or Plaka village for sunset views. Pro tip: Hit it in May or September to beat the heat—pair with a boat trip to nearby Kimolos for extra seclusion. Fresh seafood at a taverna? Don’t skip the grilled octopus.
