If you've been on Benidorm beach, you'll have spotted a mysterious rocky outcrop in the horizon. Locals call it Peacock Island because of the birds that make it their home – and at just 3.5km away, it makes a great trip by boat from the mainland.

You'll board the boat for the 30-minute cruise to Benidorm Island – its real name – and then have free time to wander around it at your own pace. There's a café down by the quay and there are marked pathways going up to the lighthouse, which is on a cliff with a 73m drop to the sea.

And from the summit, you'll enjoy great views of the coastline, which stretches all the way from Alicante in the south to the Puig Campana mountain to the north.
