Greece has six main island groups and hundreds of ferry routes, which makes planning a first island-hopping trip genuinely confusing. This guide explains how the ferry system works, how many islands are realistic in a week or two, what each major cluster offers, and why the Sporades — Skiathos, Skopelos and Alonissos — deserve a place on the shortlist alongside the better-known Cyclades circuit.

Every number you need to plan a Skiathos trip: monthly average air temperatures, sea temperatures, rainfall and sunshine hours for all twelve months. The swimming season runs May to October, with June and September offering the best balance of warm water, low crowds and reliable sun.

Skiathos Town is the island's only town and its social heartbeat — a compact, walkable port with two harbours, whitewashed alleys, Greece's most beloved literary house-museum, and a waterfront that comes alive every evening. Here's how to navigate it like someone who actually knows the place.
