We will start our kayaking session from the beach near the Martello Tower. We will paddle to Shenick Island first; it should take us 20 minutes. Then we will land there and take some pictures. Afterward, we will paddle to Colt Island for about another 20 minutes and take a well-deserved break there. Early writers tell how an island off Skerries was used as a landing place for an invasion, which happened in the second century. This island was either Shenick or Red Island, which would have been a tidal island at the time. When the invaders landed, they formed ranks and at low tide marched to the mainland, where they were promptly defeated at the ancient settlement of Knocknagin, north of Balbriggan.
