Snorkelling & Diving in Corfu

Where to go

  • Paleokastritsa (west coast)
  • Nissaki (northeast)
  • Kassiopi & Acharavi (north)
  • Sidari & Canal d’Amour (northwest)
  • Agios Georgios Pagon (northwest)

Paleokastritsa – caves, coves and calm water

Corfu’s west-coast star is famous for its limestone cliffs and a trio of sea caves — Blue Eye, Nausika and Saint Nicholas — reachable by small boats from the main beach. The sheltered, transparent water makes it superb for first-time snorkellers and relaxed dives along rock walls teeming with small fish. Locals will tell you that mornings are the best here, before tour boats crowd the bay. If you swim out just past the line of rented pedalos, you will often see octopus hiding under flat stones and darting through crevices. Colovri in Paleokastritsa stands out as the most renowned diving spot in Corfu. This small 2,000-square-meter islet is encircled by a fascinating labyrinth of rocks, tunnels, arches, and underwater passages waiting to be explored. The site teems with marine life — from colorful Anthias and shrimp to barracudas, moray eels, and countless reef species. As you approach the outer edge of this stunning reef, the seafloor suddenly drops into a dramatic underwater wall descending into the deep blue. It’s a breathtaking experience for any diver. The maximum depth reaches around 40 meters, but even beginners will find an abundance of beauty and adventure in the shallower areas.

Getting there: Drive ~25 km from Corfu Town, or use the Green Buses northbound service (A9 Paleokastritsa). Boats depart right off the central beach.

Nissaki – pebble bays and an easy gateway to reefs

On the northeast coast beneath Mount Pantokrator, Nissaki’s small pebble coves offer quick entry to clear, gently sloping seabeds ideal for snorkelling. It’s also a hub for dive schools running beginner try-dives and guided reef or wall dives along the craggy NE shoreline. The eastern side of Corfu generally has calmer seas, which is why many instructors prefer starting new divers here. We often bring friends to Nissaki when they’re nervous about currents, because the water clarity is almost always excellent.

Getting there: By car (~40 minutes from town) or by Green Buses (A5 Barbati–Nissaki). Many visitors also rent boats to explore nearby coves.

Kassiopi & Acharavi – arches, walls and convenient training dives

Further north, Kassiopi’s headlands shelter rocky ledges and arches that suit guided dives when conditions are calm. Even when a local dive school is closed seasonally, centres based nearby in Acharavi pick up the slack with try-dives and certified trips. The seabed here has an interesting mix of volcanic-looking rock and seagrass, where you might spot moray eels. Those who stay long enough in Acharavi know that sunset snorkels, when the water glows copper, are unforgettable.

Getting there: By car (~36 km from town) or via the A4 Kassiopi bus; Acharavi sits on the A3 route.

Sidari & the Canal d’Amour – sandstone channels made for masks

Sidari’s photogenic Canal d’Amour is a natural maze of soft sandstone channels and mini-bays. On calm days, these protected inlets can be fun for snorkellers weaving between honey-coloured walls; do check conditions, as swell and crowds change the experience. Many locals warn not to underestimate the current on windy afternoons. If you go, slip into the water early and aim for the smaller side coves, where you’ll often have the space to yourself.

Getting there: Drive roughly 37 km from town or take the A2 Sidari bus; short local walks connect different coves once you’re there.

Agios Georgios Pagon – big horseshoe bay with easy entry

Northwest-facing Agios Georgios (Pagon) is a vast crescent with glassy water most mornings, good for long shoreline snorkels over sand-to-rock transitions and relaxed intro dives. It’s a favourite for families: tavernas line the beach and you can leave your mask and fins on the sand while you pause for grilled fish. If you are lucky, dolphins occasionally pass further out in the bay — locals know to keep an eye on the horizon.

Getting there: By car (~45–60 minutes) or the A7 Agios Georgios (Pagon) Green Bus from Corfu Town; some services also link to Sidari.

Practical tips

  • Wind & clarity: The northeast (Nissaki/Kassiopi) often stays clearer when the west gets choppy, while mornings on the west (Paleokastritsa/Agios Georgios) can be glass-calm before onshore breezes pick up. Check the beach flags — if they flap inland, expect surface chop.
  • Cave trips (Paleokastritsa): Small local boats run frequent short tours — bring reef-safe sunscreen and footwear for pebble entries.
  • Safety: Avoid cliff jumping; watch boat traffic near cave mouths; use a surface buoy if snorkelling far from shore.

Why these spots?

Traveller reports consistently highlight Paleokastritsa’s cave-and-cove combo for snorkelling, Nissaki’s easy access and reliable dive operators, Kassiopi/Acharavi’s convenient training dives, the iconic (when-calm) Canal d’Amour swim, and Agios Georgios Pagon’s clear, beginner-friendly bay. Together they spread you across west, north and northeast Corfu — exactly where the island’s most inviting underwater scenery concentrates. Living here, we know Corfu’s underwater world is often underestimated compared to its beaches, yet those who slip beneath the surface discover a quieter, more authentic rhythm of the island. You’ll leave with salt on your lips, a sun-warmed back, and the memory of tiny silver fish scattering before your mask — and that is what Corfu is really about.
