Take a walk
Portstewart Strand is the start point for the 33 mile (53km) long Causeway Coast Way to Ballycastle. If you fancy a shorter walk you can choose between walks along the strand or a 2 mile (3.2km) long circular route in the dunes.
The Bann Estuary
Enjoy a quiet break from the busy beach and watch fisherman going up and down the River Bann. The saltmarsh is a haven for different flora and fauna than the dunes.
Wildlife to spot
For everyone who loves birdwatching make sure you find the birdhide across the river Bann. It offers perfect conditions to watch the birds that feed and live in the Bann Estuary.
There's something to see whatever the season. Whales, dolphins and seals can be seen from the beach. And the dunes vibrate in colour with butterflies, moths and wild flowers.
Take to the water
