Reef-and-chimney Koh Haa site with mild current and rich life.
Boat access and park logistics make a local guide the practical default.
Koh Haa Neua #1 is the northern Koh Haa reef-and-chimney site, blending a shallow coral start, swim-through structure, and a standout vertical section that rewards steady buoyancy. It is usually dived by boat and suits a broad range of divers because current is often mild, but the enclosed passage still asks for discipline and a guide who knows the park conditions. The reef edges, boulders, and coral gardens support a lot of life, from schooling fish and macro subjects to occasional larger visitors.

Scuba Diving
Reef, swim-through, and chimney-style structure with a shallow coral start, boulders, and a vertical chimney. Good buoyancy matters through the enclosed section.
Freediving
Not a primary freedive target; the enclosed chimney and boat logistics make scuba the better fit.
Snorkeling
The shallower Koh Haa sections work for snorkelling on calm days, but the chimney and caverns are scuba-first.
