Marine Gardens is a coastal site in Northern England where the River Wyre meets the sea. The topography consists of a mix of sandy and rocky seabed, accessible via a slipway. This site is suitable for beginners, though conditions vary significantly due to the presence of strong currents, rip currents, and surf. Water temperatures range from 7C in winter to 18C in August. Facilities available at the site include parking, toilets, and a cafe. Snorkellers should exercise caution regarding the water movement and local conditions when planning their visit.

Hilbre Island is the largest of three tidal islands situated in the Dee Estuary. Snorkelling is best conducted around the old lifeboat slipway during high tide, where the rocky seabed provides a habitat for various temperate marine life. The site is suited for intermediate snorkellers who can manage shore entries in variable conditions. Water temperatures fluctuate throughout the year, ranging from 7C in winter to 18C in late summer. The environment supports a variety of temperate marine life, including crustaceans and small fish typical of this coastal habitat. Visitors should be aware of the tidal nature of the island when planning their visit.
