Why divers know this place
Highlights
The experience of diving on the Ilhéus das Formigas (Formigas Islets) begins when you board the boat for the 33-nautical-mile trip from the southeast tip of São Miguel, or the 20-mile trip from the island of Santa Maria. The remote location and strong currents mean that it is only recommended for experienced divers, but for those that have dive skills this is one of the best sites in the Azores. Many divers opt to combine this dive with Dollabarat Reef, another marine reserve in close proximity. The long trip from any of the islands is in itself a great adventure, allowing divers to see cetaceans, turtles and seabirds on their journey toward the islets, marked by a small lighthouse. Even before dropping the anchor, you can see some of the schools of fish that abound in these crystal clear waters, such as Bermuda chubs (Kyphosus sectator), grey triggerfish (Balistes carolinensis) and Almaco jacks (Seriola spp.).

The displayed coordinates are rounded locality points only—not an entry, launch, marina pickup, mooring, reef top, wreck position, cave entrance, descent point or navigation waypoint.
Plan within your training
Conditions and hazards
Open-Atlantic swell, changing visibility, surge and surface traffic are possible. Dive only with a current local operator and abort when conditions exceed training or the briefing. Moderate to strong current is documented; use appropriate drift/current procedures, surface signalling, live-boat support and conservative gas planning. Deeper routes require certification, gas planning, ascent discipline and decompression awareness; do not exceed personal or agency limits. Treat wreck or archaeological material as a no-touch feature. No penetration without wreck/overhead training, redundant gas, guideline and explicit operator approval; watch for sharp metal and entanglement. Remote boat access increases evacuation exposure; require suitable sea state, oxygen, communications, reserves and a documented emergency plan.

Facilities and support
Use a licensed local dive center. Confirm transport, rental equipment, gas availability, emergency oxygen, communications, recall procedures, environmental restrictions and the current hyperbaric/emergency plan before departure.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
