We did the ebike ride and hike, and Tim was our guide. There were only four of us - one the benefits of booking an activity on our own rather than through the cruise ship - and Tim was a fantastic guide. He clearly knows a lot about the area's flora and fauna and is very enthusiastic about sharing it with visitors. We got lucky and had a beautiful, sunny and warm day, which showed off Ketchikan at its best. The bikes were easy and fun to ride, the hike was a pretty easy walk through the park down to the beach, and at low tide we could walk onto the beach and check out all sorts of sealife in the sand and water. A great way to spend a few hours. There were only two kayakers that afternoon, and I was a little jealous of them being out on the water on such a nice day. They were also very complementary of their trip and guide, Tom.
