9 Overtourism Destinations to Avoid in 2026 (And Where to Go Instead)

4. Santorini, Greece: The Overwhelmed Island Paradise

Santorini's iconic blue-domed churches and stunning sunsets are renowned worldwide, but the island's infrastructure is buckling under the pressure of mass tourism. The narrow streets and limited accommodations can make visiting Santorini during peak season a daunting task. As an alternative, consider the island of Naxos, which offers beautiful beaches, rich history, and a vibrant local culture. Naxos provides a more authentic Greek island experience, where travelers can explore ancient ruins, enjoy local cuisine, and relax on uncrowded beaches, all while supporting sustainable tourism efforts.
