We did all 3--kayak, bike and hike with tour guide Derek. It was a beautiful sunny day (so we didn't see any whales) and all of the excursions were absolutely wonderful. The kayaks seat 2 people in each one, so with an odd number of guest we had one person to share the kayak with Derek, which worked out perfectly that my stepmom could sit back and enjoy while he did most of the work. We are a family, all adults, ages late 20s - late 50s and for the most part we were all able to do all of the activities. We had one rider who doesn't do so well on bikes, and they drove her to the hike site while the rest of us rode the ebikes, which were a lot of fun. The hike was amazing! We didn't go far on the trail, but we got to go down by the water and had some of the best photos from our whole trip to Alaska. We would highly recommend this tour to everyone, you get to see so many sites that would be hard to locate for someone not familiar with the area and we got so much in in the time we had in port from our cruise ship.
