My husband and I are in our late fifties and had never kayaked before. Everyone in our group had and they were all much younger, but everything was explained so well and the kayaks (a bit wider) and paddles are specially designed, easy to use, so we had no trouble at all.
We didn't see a lot of fish due to Ian making the water silty, but it was still really cool being out on the water under the night sky with the lights of the city sparkling in the distance and the pretty glow of the kayaks all around. We would definitely do this again.
