Snorkellers will be able to choose from three trails in the bay.
The trail has been created by the charity in partnership with the Bouley Bay Dive Centre.
It is the island’s second trail after Blue Marine, in partnership with the Société Jersiaise and others, launched one at Portelet last summer, where there are four routes to follow.

Those who wish to join the first snorkel at 15:00 on Saturday 27 May are asked to bring their own equipment – such as a mask, snorkel, fins and wetsuit – as this will not be provided.
