Captain Jake clearly makes this tour special. Reviewers consistently praise his warmth, humor, and ability to engage everyone from kids to adults. He's known for letting children steer the boat and pose in his captain's hat, creating memorable moments that families rave about. His knowledge of Redondo Beach history and local marine life adds educational value without feeling like a lecture, striking a nice balance between entertainment and learning. The 50-minute tour offers more than you might expect. Beyond viewing fish through the glass bottom, you'll likely spot sea lions up close and hear fascinating stories about the harbor's past. The ride is smooth and comfortable, making it suitable for all ages without concerns about seasickness. It's an easy online booking process, and the experience consistently delivers value. Locals and tourists alike call it a hidden gem at the pier, perfect for filling an afternoon with something genuinely enjoyable rather than just another typical activity.
My first time visiting Redondo Pier, and the bottom glass boat came up as I was planning my visit and things to do. Bought my tickets online, it was an easy process. The ride was about 50 minutes, and it was a great experience. The Captain gave us history of the pier and surroundings. We viewed sea lions from the deck, then went downstairs to see the fish, a lot of them!!! It was very fun. Highly recommend this excursion.
