Posidonia oceanica seagrass meadows surrounding Menorca are strictly protected. Anchoring boats on posidonia beds is one of the most heavily fined environmental offences in the Balearics, with penalties up to €10,000 for recreational vessels. The seagrass is a critical marine ecosystem that provides oxygen, absorbs carbon, and supports fish populations. Satellite monitoring and patrol boats actively enforce this.

All coastal waters around Menorca, especially Fornells Bay, Cala Galdana, Addaia harbour, and the south coast calas.

Purchasing counterfeit goods (fake designer bags, watches, sunglasses, clothing) from street vendors is illegal for the buyer in Spain, not just the seller. Under the Citizen Safety Law, buyers can be fined €500 to €10,000. Police conduct regular operations targeting counterfeit goods sales at markets and tourist areas. Your items will be confiscated and you'll receive an on-the-spot fine.

Spain requires hotels, short-term rentals, campsites and vehicle-hire firms to register their customers and transmit the data to the Ministry of the Interior. Real Decreto 933/2021 places that duty on the business, and its penalties fall there: failing to keep the register or to send the communications is a serious infraction under the public security act. None of it is chargeable to you as a guest. What can happen to a traveller is a different thing and is not a fine — a border officer may ask where you are staying and may refuse entry if you cannot say. Carry the booking confirmation for that reason, not because of a penalty.
