Aldermens-Middle Middle is a remote boat dive with broad grassy gullies.
Boat or charter access is the normal way to reach the site, and operators time trips around the weather.
A remote boat dive in the Alderman Islands with broad, grass-lined gullies and rocky structure that reward slow, exploratory swims. The site is best on settled sea days and suits divers comfortable with offshore boat logistics. Small reef fish gather in the grass, and crayfish are often found along the larger cuts. The open-water setting makes it a better fit for a calm-weather charter day than a rushed in-and-out stop.
