We have extended our Celtic Deep trip for those wanting to maximise their time in the Deeps. Join us on a unique adventure where we explore the rich waters of the Celtic Deep 30 miles offshore. Our focus will be on encountering blue sharks but our wish list of possible species includes porbeagle sharks, sunfish, minke & fin whales, common & bottlenose dolphins and bluefin tuna. All have been sighted on this trip. Orca and humpback whales are also infrequently encountered in this area. The extra day provides flexibility if conditions dictate. We can explore the Pembrokeshire islands swimming with seals and on the lookout for basking sharks around The Smalls, Grassholm, Skomer, Skokholm as well as freediving wrecks and reefs.

**Please note we use a booking system to be able to handle the bookings. There is a 6% booking fee added to the total. This is a direct fee for the booking company to handle our business.  Celtic Deep do not keep this money.  By using this system our time can be spent focusing on the tours and you as customers. 

**All our trips are at the mercy of the weather, should we get blown out for the main destination we will inform you in as far advance as possible, you will then have the option to have a voucher to use on another trip, a refund, or an alternative activity such as an introduction to freediving course, coasteering, kayaking, surfing. 

Deposit Only Payment

Remaining 50% of payment will be automatically charged 1 week before the start date of the activity.
