They offer a wide range of fun activities for all the family to enjoy.

Marine Life Walks and Ecology Talks

Mulberry Divers is a SSI Blue Oceans Centre, located in Selsey, West Sussex and we are lucky enough to have the Selsey Bill and the Hounds Marine Conservation Zones (MCZ) extending from our beaches to the Mixon Hole. The ecosystems here provide a home for some amazing life and we want to help you discover it! 

Walks are led by a qualified SSI Marine Ecology Instructor who during your walk will show you where to find some of the life on our shores and provide you with facts and information about those residents and the ones you cannot see. If you enjoy rock pooling this is a great family activity. Each walk lasts for about 1.5 hours and we visit a variety of sites in Selsey, including Selsey Bill, East Beach near Pagham Harbour, Selsey Lifeboat Station and West Beach. If you come prepared to wade in shallow water, you can see even more! You are welcome to bring a camera to record your walk. 

Walks are offered every Wednesday at West Sands meeting at 11:00 outside the exterior entrance to The Oasis, West Sands.

Marine Life Walk with Ecology Talk 

If you would like to learn more about the local Selsey marine life and seas, why not consider completing an ecology talk prior to your walk. We offer a three-hour online class that can be delivered online to you. We will look at the ecosystems, residents, challenges they face and things we can do help. The course is taught as an introduction to Marine Ecology and is focused on local marine life and biodiversity that you might see when walking, snorkelling, freediving, or scuba diving at Selsey. During the walk we look at and discuss what you learnt about on the talk.

Guided Snorkel Tours 

Just off the beach at Selsey, there is one of the UKs designated Marine Conservation Zones (MCZ), Selsey Bill and the Hounds which includes the Mixon Hole. Accessible from the shore and by boat the MCZ provides a home for some amazing life. From tiny fish and prawns to large wrasse and rays there is so much to see if you know where to look. Snorkellers generally get closer to the life than divers, you are quieter, and it is often inquisitive. 

Shore Snorkel Tours – Led by a SSI Professional these tours give the opportunity for participants to practice their skills under guidance, improve technique and learn where to look for life. We start by looking at safety procedures and practice in shallow water, before heading off to explore sites around Selsey including Selsey Lifeboat Station, East Beach and West Beach. Each tour will last about 1.5 hours. 

No previous experience is required, you just need to be water confident and able to swim at least 20ms unaided. We do cover everything you need on this tour however a Try Snorkel pool session first is excellent for teaching basic skills, how to get the best out of your equipment and building confidence so you can concentrate on having fun. A great family activity, children over 10 are welcome we just ask that they are accompanied by an adult. We encourage you to bring along a waterproof camera, you never know who we might see!!
