Country shortlist
The Double Fathom shortlist for Greece, ranked — 1 catalog destination. The grouping is ours; every rank and tagline is the catalog’s own.
Greece is where the Mediterranean shows off: some of the clearest water in the basin, spread across island groups rather than concentrated in one place. Our catalog's Greek sites span the Cyclades, the Sporades, Zakynthos, Crete and the Ionian coves — Aegean and Ionian water, sea caves, a national marine park and blue-shadowed drop-offs between the islands. What they share is clarity and ease: the ferry network is the logistics plan, and the swimming is largely self-guided once you are there.
What we cover — and what we don’t
Where we cover Greece: one destination, five sites across the Cyclades, the Sporades, Zakynthos and the Ionian, and Crete. Marine-park sites need a licensed operator — the park's own rules are on the site pages.
In catalog rank order. Rank, taglines and “best for” notes are the catalog’s own; each destination page and guide goes deeper.
Med's clearest water
Aegean and Ionian azure — drop-offs, sea caves and late-summer clarity between the islands.
Some of the clearest water in the Mediterranean, blue-shadowed sea caves and island-hopping logistics that make it easy to build a varied, self-guided snorkel trip.
This country sits inside the Mediterranean — the wider grouping the ranked catalog uses.
Each country page groups the ranked catalog by country and states plainly what this catalog covers — and what it does not.
