Richelieu Rock

Richelieu Rock is Thailand's consensus number one, an isolated horseshoe of limestone in open sea whose every surface is upholstered in magenta soft coral. The site runs both ends of the scale simultaneously: glassfish and snapper in humming walls, trevally and Spanish mackerel cutting lanes through them, seasonal whale sharks looming out of the plankton haze between roughly February and April, while inches from the rock, tigertail seahorses, harlequin shrimp, ornate ghost pipefish, and frogfish carry the macro program. Multiple dives here on one trip are standard and never redundant. Current, crowds, and brilliance arrive together; all three are part of the experience.

Khoảnh khắc bạn đến vì nó: Purple soft-coral pinnacle, seasonal whale sharks, world-class macro on the same rock

Địa hình: Limestone pinnacle cluster wrapped in purple soft coral

Dòng chảy: Current sets the day's plan; the horseshoe's inner curve gives shelter while the outer faces fly.

Điểm vào: Reached by liveaboard or long-range day boat; the horseshoe barely breaks the surface at low tide and dives are tide-planned.

Nguy hiểm cần lưu ý: Strong current and boat congestion at the moorings; watch the blue on ascent for traffic.

Giấy phép & quy định: Park fees apply; the site closes with the annual mid-May to mid-October park closure.

Bảo tồn: Within Thailand's marine national park system with fees and mooring rules; no gloves, no contact with the dressed rock.

Nitrox: Đáng dùng ở đây — các hồ sơ nằm trong khoảng độ sâu mà nitrox có thể kéo dài thời gian không dừng một cách thực sự có ý nghĩa (khi đã được đào tạo sử dụng).
