Can't say enough positive about Justin and this experience.
It was all of our first time kayaking- two adults and three kids. Justin made us feel at ease and got us off to a great start.
And, he had great stories about Napa. He is a local having grown up right there in Napa, so that brought a great "insider" feel to his stories. They were not dry at all- were like a local person telling you the inside scoop on the town- good bad and ugly.
He had several "dark side of Napa" stories but kept them acceptable for the kids.
And he was so great in memorizing our names, and would direct different comments to each of us to make us feel included and engaged.
At the end of the tour he gave us 45 min or so to kayak on our own. So, it was a good combination of organized tour and free time on our own.
HIGHLY HIGHLY recommend this tour!
