Na Bosca is a simple boat dive with strong photo potential.
Na Bosca is a boat dive off Tossa de Mar built around two rock formations and a sandy channel that form a simple, photogenic loop. The route is easy to navigate, delivers plenty of Mediterranean life, and works well for divers who want relaxed bottom time, strong visibility, and a site that rewards careful looking rather than heavy exertion.

Scuba Diving
A short boat ride leads to a simple route around the larger rock and through the sandy channel.

Snorkeling
Snorkeling is limited because the interesting route sits around the rocks and channel rather than right at the surface.
