In the UK, we’re never more than 70 miles from the coast, and the Wildlife Trust’s National Marine Week is a celebration of the wonderful seaside wildlife we have here in Britain, and with more of us enjoying holidays in the UK this year, there's more opportunity than ever to get involved and discover what the country's coastline has to offer.

From rockpool rambles to snorkel safaris and beach cleans, there are plenty of activities for people of all ages to enjoy. Here’s our guide to the best events to visit for National Marine Week 2021.

When is National Marine Week 2021?

In 2021 National Marine Week takes place from 24th July to 8th August 2021 and celebrates the varied seaside wildlife around the UK.

This year The Wildlife Trusts are asking people to make a one-minute video celebrating the shore and the creatures that live there, and post it to Instagram or Twitter using #NationalMarineWeek — you will have the chance to be featured by The Wildlife Trusts on social media and win a prize.
