Extra time on your hands? Then stroll along the river’s edge towards Mahon. It’s roughly an hour and a half’s walk. If you have a bike or roller blades you won’t be alone, it’s a super way to burn some calories and have some fun at the same time. Great couples or family activity.

Blackrock Castle Fact
The original tower was built by the citizens of Cork in 1582 to guard the water approach to the city from pirates and other raiders.
