Guide-led macro diving at Mireille
The site is described as guide-only because orientation is very precise.
Mireille is a short boat-ride macro site near the lodge that rewards divers who stay close to the guide and keep the route compact. The draw here is precision and small-life hunting rather than wide-open drifting, so it suits people who enjoy a controlled plan and tight navigation. Expect seahorses, nudibranchs, and other small reef subjects rather than a big, dramatic wall. It is a site for careful buoyancy, good awareness, and staying with the dive leader.
