Skiathos vs Skopelos

Quick Verdict

Skiathos for convenience and sand; Skopelos for villages, forest and quiet. They are twenty minutes apart, so the answer is usually both.

How they compare

Dimension	Skiathos	Skopelos
Beaches	Koukounaries is the most famous in the Sporades, with a bus route along a coast of sandy bays.	Pebbly, pine-backed and prettier: Milia, Kastani and Panormos, with fewer people on them.
Towns	Skiathos Town has the harbour, the Bourtzi peninsula and a bar scene that runs late.	Skopelos Chora is an amphitheatre of white houses with more than a hundred churches and no nightlife to speak of.
Noise	Bars, clubs, and aircraft landing at an airport on the edge of town.	Crickets and church bells; the loudest thing is a goat.
Getting there	Direct flights from Athens and Europe, and ferries from Volos.	No airport: ferry or hydrofoil from Volos, or via Skiathos.
Inland	Pine forest and the wetland behind Koukounaries — small but genuinely wild.	The greenest island in the Aegean: forest, plums, almonds and walking between villages.
In August	Busy, with the beach bars full and every ferry arriving loaded.	Busy in the port and at Kastani, quiet twenty minutes inland.

Our Verdict

Skopelos is the better island and Skiathos the easier one. Flights make Skiathos the natural entry point; three nights there and four on Skopelos, one ferry hop away, gives you both without choosing.
