Atlantic edge-of-Europe diving and waterfall hikes on the Azores biosphere island
Currently Viewing:
Overview
Flores is the Azores at its wildest: a small Atlantic island where volcanic sea cliffs drop into clear summer water and dive boats hop between caves, walls, and offshore reefs. From Santa Cruz das Flores, you can reach signature sites like Catedral (a layered wall dive) and the lava-formed Gruta do Galo. In late summer, underwater visibility often improves beyond 30 m, and sea temperatures can peak around 24°C to 25°C. Flores is also a natural launchpad for Corvo, where the famous Caneiro dos Meros sits inside a no-fishing reserve and rewards patient divers with close fish encounters. Topside, expect crater lakes, faja trails, and waterfall corridors between Fajazinha and Faja Grande, including pools like Poco do Bacalhau. Plan for fast-changing weather, limited services, and uncrowded adventures.
Flores is a UNESCO Biosphere Reserve island built around water: crater lakes on the plateau, dozens of waterfalls on the cliffs, and a rugged basalt shoreline that can feel like the end of Europe. It is small, quiet, and weather-driven. If you are flexible, the island rewards you with big Atlantic scenery and surprisingly varied diving.
Corvo is close enough for a day trip by ferry or flight when conditions allow. Underwater, Caneiro dos Meros is famous for relaxed fish behavior due to no-fishing rules. Topside, Corvo delivers a dramatic caldera hike and one of the smallest village vibes in Europe.

Trip callouts
Lava-formed sites like Gruta do Galo and Gruta dos Enxareus deliver dramatic chambers, swim-throughs, and textured basalt walls.
Late-summer visibility commonly improves beyond 30 m with sea temperatures peaking around 24°C to 25°C.
Flores Nature Park includes protected coastal zones (Costa Norte, Costa Nordeste, Costa Sul e Sudoeste, and Ponta da Caveira) plus strict seabird nesting protections.
Use Flores as your launchpad to Corvo for Caneiro dos Meros, a no-fishing reserve site known for unusually calm fish behavior.
Topside days are as strong as dive days: faja trails, high sea cliffs, and waterfall pools like Poco do Bacalhau.
scuba
Why Flores for Scuba Diving
Flores delivers classic Azores boat diving: basalt walls, lava caves, and offshore reefs that can light up with schooling fish when conditions align. Most dives are short rides from Santa Cruz das Flores, with additional options along the north and south coasts when the sea state permits. Late summer tends to bring the calmest windows and the clearest water, while spring can be productive but more variable. If you can add a weather buffer, Flores also unlocks Corvo and its famous no-fishing dive, Caneiro dos Meros.
freedive
Why Flores for Freediving
Flores is best for freedivers who want scenery and solitude more than perfect flat-water training every day. Sheltered bays, tidal pools, and short boat rides to walls can line up with late-summer calm to create excellent sessions. Because the Atlantic can change quickly, most visitors treat freediving as an opportunistic add-on to scuba days or hiking days, rather than the only reason to come.
snorkel
Why Flores for Snorkeling
Snorkeling on Flores is about volcanic coastline exploration, not tropical reefs. The island shines where lava rock creates protected pools and calm bathing areas, letting you see Atlantic reef fish without dealing with open-ocean surge. On settled days, short boat trips can also put snorkelers above shallow reef structure while divers explore deeper walls.
topside
What to do when you're not in the water
Flores is a scenery-first island: crater lakes on the plateau, steep sea cliffs lined with waterfalls, and short hikes that deliver big payoffs. Plan at least one full day for the lakes (Sete Lagoas area) and one for the west-coast fajas and waterfalls between Fajazinha and Faja Grande. If you have extra time and calm seas, add a Corvo day trip for its caldera viewpoint and village stroll.
