Freediving in Marshall Islands
Including Arno Atoll Outer Reef, Majuro Atoll Lagoon, and Milo Channel. On the map.
The vibe
The sheer vertical drop from the surface to deep blue invites breath‑hold dives that feel like a silent plunge into endless space, unique to these remote atolls. The cooler dry months bring calmer seas and clearer water, ideal for depth pursuits. Most freedivers go solo or with a small buddy crew, making it a quiet, self‑reliant outing.
