About this site
Halcyon lies off the coast of Kerala in southern India, in the waters of the Arabian Sea near Thiruvananthapuram district. This stretch of coastline is only beginning to be developed for recreational diving, with sites accessed from small coastal towns along the Kerala shore. The reef here reaches a maximum depth of around 12 metres, and despite the shallow range it is rated an advanced dive.
