When taking part on this treasure hunt, please do take care around water, we recomend that children are supervised at all times.  

Replace any seaweed you move out of the way, put back any crabs or fish, turn rocks back over and don’t scrape anything off these areas which our precious sea life call their home.  

From groynes, to rocks to concrete blocks they all play a role in keeping our sea life safe. 

If you find any human litter on the beach, please help preserve Selsey’s treasure- our sea-life and take it away with you and dispose of it safely.   Thank you.
