Tips snorkelling in Cornwall:

Snorkelling in Cornwall can offer an amazing glimpse into the rich and diverse underwater world off the Cornish Coast. However, it also comes with several risks due to the ever changing tides, currents and underwater terrain. Here’s some tips for how to enjoy snorkelling in Cornwall safely:

  • Check Weather and Sea Conditions: Always check the weather forecast and sea conditions before heading out. Calm, clear days are best for snorkelling.
  • Know the Tides: Be aware of tide times and snorkel during slack tide (the period between high and low tide) for the safest and best visibility.
  • Wear a Wetsuit: Cornwall’s waters can be cold, even in summer. A wetsuit will keep you warm and provide extra buoyancy.
  • Use a Good Quality Mask and Snorkel: Ensure your mask fits well and doesn’t leak. A high-quality snorkel will make breathing easier and more comfortable.
  • Fins for Efficiency: Fins can help you swim more efficiently and cover more ground while snorkelling.
  • Snorkel with a Buddy: Always snorkel with a partner for safety. Let someone know your plans and expected return time.
  • Stay Hydrated: Bring water and stay hydrated, especially if you’re spending a long time in the sun and saltwater.
  • Respect Marine Life: Observe marine life without disturbing it. Do not touch or chase animals and avoid stepping on or damaging corals and plants.
  • Be Mindful of Boats: Stay aware of your surroundings and keep an eye out for boats, especially in busy areas.
