Parking 1 is the easier shore entry for quarry dives and training practice, but the site still rewards careful buoyancy and navigation.
Freediving
Not a freedive-first site; scuba is the better fit for the quarry layout and changing conditions.
Snorkeling
Snorkeling is limited by the quarry layout and depth; the site is better suited to scuba.
