Bianca C Wreck

Grenada · Caribbean

The Bianca C is a 180m Italian cruise liner that sank off Grenada in 1961 — known as the 'Titanic of the Caribbean,' she sits in 30–50m and is one of the great big wreck dives in the region. Grenada's broader diving includes the underwater sculpture park.

What divers say

Swimming over the Bianca C's bow at 30m as schools of jacks pour past — one of the best wrecks I've dived anywhere.
