We partner with Rewilding Britain to help protect our natural spaces for future adventures.
All centres are vetted for safety and quality. Your adventure is in good hands with adventuro.
On Selsey’s beaches, you can explore the intertidal zone and meet its residents, from crabs and shellfish to seaweeds and small fish. These guided walks show how these species live, interact, and survive in their habitats. Walks are interactive, family-friendly, and each session is unique depending on tides and seasonal wildlife.
Starting along sandy and shingle stretches, a SSI Marine Ecology Instructor will guide you to tidal pools, groynes, and mussel beds. You’ll learn about the behaviours and daily life of marine residents while observing them in their natural habitats. The instructor will answer questions, point out subtle species, and show how to spot creatures that are easy to miss.
As the walk progresses, opportunities arise to observe life up close without disturbing it. You can take photos, ask questions, and follow the instructor’s guidance to explore safely. Each walk is shaped by tides, weather, and seasonal changes, so no two experiences are exactly alike.
Optional shallow wading provides an even closer view of marine life. Instructors provide tips for staying safe while maximising observation and learning opportunities. By the end, you’ll gain a detailed understanding of the ecology, adaptations, and diversity of Selsey’s intertidal zone.
Walks take place along Selsey’s coast, eight miles south of Chichester on the Manhood Peninsula. This area features shingle beaches, tidal pools, and mussel beds that form part of the Hounds Marine Conservation Zone. It supports a wide variety of species including crabs, fish, shellfish, seaweeds, and other intertidal creatures.
Locations include Selsey Bill, East Beach, and areas near the Lifeboat Station, giving access to different habitats and experiences. The coastline has been carefully surveyed and monitored for years, allowing the instructors to provide accurate, educational insights while ensuring minimal environmental impact.
No previous experience in marine life is required. Walks are designed for families, nature enthusiasts, and anyone interested in exploring the coast. Instructors adjust explanations and pace to suit the group and ensure safety throughout the session.
Clothing should be suitable for coastal conditions with shoes that provide grip on shingle and groynes. Waterproof footwear is recommended if wading is planned. Curiosity, questions, and a camera will make the experience more enjoyable and educational.
The business is a second-generation, family-run organisation committed to connecting people with the Sussex marine environment. Small group walks minimise environmental impact while ensuring personal attention. Every session contributes directly to marine education, conservation, and citizen science projects in the area.
Over 18 years, the team has developed a broad programme that includes snorkeling, freediving, mermaiding, marine ecology education, and SSI certified courses. They are committed to sustainable practices: local suppliers are used wherever possible, waste is minimised, and all activities emphasise respect for wildlife with a strict “look but don’t touch” policy.
Participants support the Blue Oceans pledge, funding local education, beach cleans, citizen science monitoring, and children's clubs. Instructors run events like Seasearch surveys, egg case recording for sharks and rays, and kelp mapping. The walks are also an opportunity to see how local marine ecology is actively monitored and protected.
Yes, walks are designed to engage children through observation, discussion, and interactive activities. Species identification, behavioural explanations, and hands-on learning (without touching animals) help children connect with marine life.
Children may need supervision on shingle and near tidal pools. Instructors tailor the pace and content for younger participants, making the walk enjoyable, safe, and educational.
Sturdy shoes suitable for shingle and groynes are essential. Layered clothing is best for coastal weather, with hats and sunscreen recommended in sunny conditions.
If wading in shallow water, waterproof footwear and clothing are advised. Participants may also bring a small bag for personal items. Clothing should allow comfortable movement and protection from wind or rain.
Photography is encouraged to capture wildlife and habitats without disturbing them. Instructors highlight photogenic areas and provide tips for framing small or hidden species.
Care should be taken not to interfere with wildlife, especially in tidal pools. Cameras are for personal or educational use, following guidance from the instructor for safety and ecological respect.
Walks are low intensity, covering short distances over shingle and groynes, with occasional bending or kneeling to observe creatures closely.
Routes can be adapted for participants with mobility concerns. The pace is flexible to accommodate families, adults, and children, ensuring everyone can enjoy the experience comfortably.
Some areas may be challenging due to shingle and groynes. Alternative accessible routes are available on request.
Booking in advance allows the team to plan an adapted route, providing access to marine habitats while maintaining safety and enjoyment.
Walks typically last 1.5 hours, providing time to explore, ask questions, and photograph marine life.
The pace is adaptable to group needs. Breaks can be taken for observation, discussion, and photography without rushing.
