My husband and I did this as our first excursion as part of a Star Princess Cruise. We LOVED it! The e-bikes made it fun and not too strenuous (it's only about 10 miles round trip to/from the rainforest). The beauty and peace of the rainforest was incredible and our guide, Austin, made it so enjoyable and educational! Plenty of time to go at our own pace, stop for photos, ask questions, pick a few yummy blueberries to eat and walk the beach a bit. There were only 4 of us, so that was nice! And, when we were done, enjoyed a good Alaskan beer and some yummy salmon, crackers and fruit on the dock. Highly recommend it!!!
