We live in Homer and like to go across Kachemak Bay to the village of Seldovia in the summer to hike and wander around. We have used the high speed ferry in the past, but their rates for children have dramatically increased over the past couple of years. We tried out Rainbow Tours wildlife trip to Seldovia since kids go cheaper, and they encourage you to bring your dog. We have a yellow lab who came along with us.
You will go by Gull Island, which the high speed ferry no longer does.
You'll see seabirds, otters, and maybe even a seal or sea lion. Very rarely, you may also see some orcas. We never have. The boat was nice (although it was not the one listed on their website and did not have the promised bar). The crew was very friendly and even offered a bowl of water to the dog.
The bad: The trip over can be long, depending on how much wildlife is out and about when you go. Our trip took 2.5 hours! That left less time to explore Seldovia. When we arrived, we were told that we were leaving to go back to Homer at 3:30 rather than the 4:00 departure time listed on the website. So we only had a total of 2.5 hours in Seldovia.
We hiked the Otterbahn Trail very quickly, stopping for about 15 minutes at the beach. We had just enough time left to stop at the ice cream shop in town on our way back to the boat.
If you have never been to Alaska, Homer, or Seldovia before, you may enjoy this tour because it has a wildlife aspect to it. If you just want transportation to and from Seldovia, take the high speed ferry. It costs more, but you also get more time at your destination.
