Safety · Destination Guide
Three Tuscan seascapes, one flexible Mediterranean dive journey
The main safety challenge is not extreme current but the combination of depth, open-water boat operations, weather-dependent island crossings and remote response time. Use a reputable local operator, keep one no-fly and weather buffer at the end of the trip, and carry dive-specific insurance. Giannutri adds legal complexity: know the zone before entering the water and verify the current park notice.
Conservation is practical, not decorative. Do not anchor on Posidonia, touch gorgonians or red coral, collect organisms, feed fish, or enter closed marine zones. On land, remain on Giglio trails and use a guide where Giannutri requires one. Take all waste back to the mainland or established island collection points.
Use a surface marker buoy for open-water ascents and stay within the skipper's pickup plan. Clear water can make a steep wall feel shallower than it is, so pre-set maximum depth, gas turn and decompression limits. Thermoclines make deep water materially colder than the surface. Caves, arches and wrecks are overhead environments; do not enter beyond daylight or training.
Freedivers must use active one-up, one-down supervision and a visible float. Snorkelers should remain outside ferry approaches and active boat lanes. Any suspected decompression illness, arterial gas embolism, serious barotrauma or loss of consciousness is an emergency. Give oxygen if trained and equipped, call emergency services, and contact DAN. Do not drive a symptomatic diver in search of a chamber.
The nearest substantial mainland medical support is in the Orbetello and Grosseto area, with Ospedale San Giovanni di Dio in Orbetello serving the local coast. Island incidents may require Coast Guard or helicopter evacuation, and timing depends on sea state, location and clinical priority.
For a life-threatening or dive-related emergency, call 112. For a maritime rescue, call the Italian Coast Guard on 1530. DAN Europe provides 24-hour dive-medicine coordination at +39 0642115685. Emergency services, not the traveler, should choose the receiving hospital and any recompression facility. Carry certification, insurance and emergency-contact details in a waterproof form on the boat.
No Authorized Giannutri Buoy Field in 2026
The park revoked the former buoy-field rules on 25 February 2026 after the infrastructure became nonoperational. Zone 2 scuba is temporarily permitted, but lawful boat handling, habitat protection and all other safety rules still apply. Verify for later changes.
Giannutri Zone 1 Is Closed
Do not enter, swim, scuba, navigate, stop or anchor in Zone 1. A beautiful shoreline is not evidence of legal access.
Island Crossings Are Weather-Dependent
Wind and rough seas can cancel ferries, close ports or force the dive boat to stay near Monte Argentario. Keep tickets and daily plans flexible.
Depth Builds Quickly on Walls
Clear water can hide depth progression. Set a hard maximum depth, watch gas and decompression status, and do not follow the guide below your training.
Do Not Do This
Avoid entering when no authorized giannutri buoy field in 2026. Confirm local briefings before committing.
