Best places to dive with Giant oceanic manta ray
Mobula birostris
The larger of the two manta species, with a wingspan that can exceed 6-7m. Socorro is one of the few places in the world where giant oceanic mantas are reliably resident at cleaning stations year-round, and they're known here for approaching divers directly rather than keeping their distance.

Long-term photo-ID recorded a concentrated March–May passage, often lasting only two to four weeks. Individuals are transient and usually remain for a day or two; timing varies between years.

Black Rock is the site. Scientific dive surveys and citizen-science submissions logged 276 encounters across Black Rock and the Twins since 2011, with 216 individuals photo-identified and up to 28 in a single day; over 95% of those were at Black Rock. Operators report mantas from late January to early May with the best odds in February and March. Blank dives are common — this is not a guaranteed encounter, and the published numbers cover fourteen years of effort, not a single season.

Much less predictable than the reef manta and effectively a south Komodo animal — Manta Alley is the site where operators report them, in current-driven conditions, and they are rarely seen at the central cleaning stations. Coded occasional over the southeast monsoon (May-October) to follow the same upwelling that concentrates reef mantas in the south, and rare otherwise. This is an operator-reported pattern rather than a study-backed one; the PeerJ photo-ID work covers reef mantas (Mobula alfredi) only.

Mantas around Sharm are chiefly oceanic manta (Mobula birostris), seen as occasional summer visitors (roughly May to October) rather than reliably resident. A 2022 study recorded the Red Sea's highest individual count near Sharm, but encounters here remain occasional.
