Ilhéu da Mina
Also known as: Mina Islet
A boat-only islet dive off Terceira's south coast, with a 20m wall into wide ravines, then a reef rising to 3m and a 35m black-coral pinnacle beyond.

The dive
The dive begins right at the surface beside the islet, then follows a vertical rock wall down to 20 metres, opening into a series of wide ravines. From there the route crosses to a separate reef that rises from 25 metres up to just 3 metres below the surface, close enough to bring the shallow and deep halves of the outing into one profile. Skirting the reef's southern edge continues the descent to a rock pinnacle at 35 metres, roughly 15 metres tall, its surface carrying large branches of black coral. Yellowmouth barracuda and almaco jack move over the reef in loose schools, feeding on blue jack mackerel below, and dusky grouper are often encountered near the pinnacle itself.
What makes it special
Official tourism material markets Ilhéu da Mina as suitable for "all divers" and even snorkellers, describing only the shallow entry beside the islet. That framing leaves out the wall itself: even the near-shore option already runs past Open Water's depth ceiling, so the practical audience for this site is narrower than the marketing suggests. What the extra certification buys in return is the reason to keep heading south along the reef: black coral thick enough to draw wide-angle divers to the pinnacle, with barracuda and almaco jack schooling above it and dusky grouper worked into the rock nearby.
Know before you go
Boat access runs about 25 minutes from Angra do Heroísmo Harbour or 20 minutes from Praia da Vitória, arriving at an islet roughly 50 metres offshore. The near-shore wall already passes Open Water's depth limit at 20 metres, so treat Advanced Open Water as the entry requirement for even the shallow half of this dive. Continuing south to the pinnacle is a separate, deeper dive within the same outing and calls for deep-diver training. No permit, fee or marine-reserve rule applies here; the site sits outside the Underwater Archaeological Park of Angra do Heroismo Bay, the heritage zone covering the Lidador and Cemiterio das Ancoras dive sites elsewhere on the island.

Depth & Profile
Conditions & difficulty
The near-shore wall already passes Open Water's 18m depth limit at 20m, so the shallowest publishable option needs Advanced Open Water. The full route continuing to the 35m pinnacle needs deep-diver training.
Summary
Moderate for the shallow wall and ravines; the extended route to the 35m pinnacle is a deeper, more demanding dive within the same outing.
Safety considerations
What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.
- Depth: The route continues from the shallow wall to a separate reef and pinnacle bottoming at 35m, deeper than the AOW-graded wall option.Plan the extended route before descending; treat the pinnacle as a separate, deeper dive, not simply an extension of the shallow wall.

Frequently Asked Questions
Is Ilhéu da Mina really open to all divers, as some descriptions suggest?▾
Not for its full profile. The near-shore wall alone descends to 20 metres, already past the Open Water certification limit, so Advanced Open Water is the practical minimum even for the shallow half of the dive. The extended route south to the 35-metre pinnacle needs deep-diver training on top of that. Framing the site as suitable for all divers and snorkelers describes surface-level access to the islet, not the training the underwater route requires.
