Travelers from other countries should check their visa requirements; many will find that they can enter visa-free for up to 6 months for tourism purposes, including scuba diving. However, it’s important to note that Guernsey is part of the Common Travel Area with the UK, Ireland, and the Isle of Man, so if you enter through the UK, you must comply with the UK’s entry requirements as well.

The summer season also brings longer daylight hours, providing ample time for both day and night dives. While diving is possible year-round, the winter months can be challenging due to colder waters and rougher sea conditions. It’s worth noting that Guernsey’s tides are some of the largest in the world, so planning dives around slack water is essential for a safe and enjoyable experience.

Dive operators, boat captains, and safety briefings will typically be conducted in English, ensuring clear and concise communication for dive planning and emergency procedures. It’s advisable to familiarize yourself with some basic diving hand signals, which are universally recognized within the diving community, to facilitate underwater communication with your dive buddy and guides.

When planning a scuba diving trip to Guernsey, it is essential to familiarize yourself with the local laws and regulations to ensure a safe and lawful experience. Guernsey, part of the Channel Islands, has specific rules to protect its marine environment. Divers must adhere to local fishing regulations, which include no-take zones and restrictions on the collection of marine life, ensuring the preservation of biodiversity. It is illegal to remove any historical artifacts from wreck sites, as many are protected by heritage laws. Additionally, divers should be aware of the regulations regarding the use of dive flags, which are mandatory for signaling the presence of divers to boats and other watercraft. The use of dive boats in Guernsey is subject to registration and safety equipment requirements. Always check for the latest information on protected areas and seasonal restrictions, as these can affect access to certain dive sites. It is advisable to dive with a local operator who is up-to-date with current regulations and can provide guidance to ensure compliance with Guernsey’s diving laws.



When planning a scuba diving trip to the picturesque waters of Guernsey, safety should be your paramount concern. Always ensure that your diving equipment is serviced and in good working order before your dive. Familiarize yourself with local diving conditions such as tides, currents, and visibility, which can vary greatly and affect your safety. It is essential to dive within your certification limits and to never dive alone; always have a buddy and maintain close communication. Be aware of the symptoms of decompression sickness and have a plan for managing it. In case of an emergency, know the location of the nearest hyperbaric chamber, which is situated at the Princess Elizabeth Hospital in St. Martin’s (telephone: +44 1481 725241). Additionally, keep the emergency contact numbers for the local coastguard (VHF Channel 16 or telephone: +44 1481 725000) and ambulance services (telephone: 112 or 999) readily accessible. Remember to inform someone onshore of your dive plan and expected return time.

Before embarking on your underwater adventure in the serene waters of Guernsey, it is crucial to ensure that your health and travel insurance policies provide comprehensive coverage for scuba diving activities. The Channel Islands, including Guernsey, are known for their captivating marine life and historic shipwrecks, but diving always carries inherent risks. Verify that your insurance covers hyperbaric treatment in the unlikely event of decompression sickness, as well as emergency medical evacuation, which can be costly without proper coverage. Since Guernsey is not part of the United Kingdom’s National Health Service, travelers from the UK should be aware that their NHS coverage will not apply. Additionally, the European Health Insurance Card (EHIC) or its successor, the UK Global Health Insurance Card (GHIC), may not provide adequate coverage for scuba diving incidents. Therefore, investing in a specialized diving insurance policy that caters to the needs of divers is highly recommended. This ensures peace of mind as you explore the underwater wonders that Guernsey has to offer.
