The main island is Santa Barbara. The lighthouse and the rangers are based here. There are two smaller islands, Isla Redonda and Isla Siriba connected by a reef.
June to September is the best time to visit as this is the season
when the whales come here to breed. A northerly wind will ensure that
the southern anchorage is calm. With a wind from a southerly or easterly
direction - none of the anchorages are comfortable.
On arrival, call "Farol de Arolhos" (the park ranger) on VHF channel 16. They will instruct you where to pick up a mooring buoy or possibly anchor.
There is a charge per person for mooring here and you MAY NOT land on either the islands or the reefs without a ranger being present. Agree the price for an island tour with the ranger beforehand.
Substantial moorings have been laid by the government and boats are obliged to use them if directed by the park ranger, to avoid damage to the coral. However, it is wise to check on your mooring before relying on it completely.
Mooring buoys are reported NE of Siriba, NW of Siriba, and S of Santa Barbara (1/4 mile E of the Lighthouse).
The Abrolhos Reefs are a nature reserve, therefore fishing, collecting and hunting are strictly forbidden. Diving and snorkeling are permitted, but beware of the currents.
