Mediterranean reserve diving, clear coves, and slow island days in Spain's biosphere island
Updated Apr 20, 2026 • 33 sources
Menorca is approachable but not consequence-free. The main safety issues are wind, overhead environments, deep wreck profiles, cliff or rock entries, boat traffic, heat, and off-season service gaps. The main conservation issues are Posidonia seagrass, marine reserve permissions, archaeological artifacts, and wildlife distance.
Use local guides for caverns, deep sites, reserve zones, and the Malakoff wreck. Carry an SMB, monitor wind and surface conditions, and do not let a named-site wish override a safe site swap. Overhead sites require appropriate training, lights, gas discipline, and buoyancy. Reserve rules restrict diving in some zones and prohibit recreational cave diving in specified marine reserve caves. Independent reserve diving requires certification, insurance, authorization, and compliance with responsible-diving criteria.
For life-threatening emergencies call 112, and for medical emergencies in Spain call 061. Menorca's public hospital is Hospital Mateu Orfila in Mahon. Dive-center listings and regional diving sources identify hyperbaric support around Mahon or Hospital Mateu Orfila, but divers should verify current chamber access with their operator and DAN before diving. Boats and centers should carry emergency oxygen and have a written evacuation plan, especially for remote north-coast or reserve departures.
Tramuntana can rewrite the day
A beautiful north-coast plan can become unsafe under northerly wind. Pick operators and itineraries that can switch coast, and do not pressure a skipper or guide to run a marginal cavern or reserve site.
Marine reserve cave restrictions are real
Balearic reserve rules include zones where diving is restricted and a prohibition on recreational cave diving inside certain marine reserves. Do not assume a cave photo online means legal or appropriate access.
Posidonia is protected habitat
Posidonia meadows are essential seagrass habitat and carbon sinks. Do not anchor on them, stand on them, drag fins through them, or treat them as expendable seaweed during snorkel or boat days.
Summer sun and rock entries are unforgiving
South-coast coves can involve long walks, hot parking areas, slippery limestone, and limited shade. Carry water, wear footwear, and treat midday freedive or snorkel plans with caution.
Menorca's protected water depends on small decisions: keep fins off Posidonia, never anchor on seagrass, do not remove pottery, amphora fragments, shells, or artifacts, and avoid feeding or touching marine life. At Illa de l'Aire and North Menorca, follow reserve zones, authorizations, and guide instructions. If you see a turtle nest, tracks, eggs, or hatchlings, stay back, avoid lights, and notify local emergency or wildlife authorities.
Do Not Do This
Avoid entering when tramuntana can rewrite the day. Confirm local briefings before committing.
