My girls and I had a great time. Damien was awesome and he provides life jackets. He also takes photos of your time on the water and airdrops them to you after the event. So you don’t have to worry about taking out your phone and dropping it in the ocean while cycling.We did have a bit of a problem finding him cuz we didn’t know he was a one man show. He doesn’t have an office there so he meets you at the harbor. So, if you see a guy carrying what looks like weight belts, that’s your guy. Otherwise, you’ll just think he’s a tourist taking photos like I did.But overall… we had a breathtakingly great time on the water with that beautiful city view that never gets old. Definitely do it again.

When I started I was scared, when I left I was smiling.My sister surprised me for my birthday with a 30-min ride. I had never before heard of the company, or any idea how to ride a water bike. I literally found out about our activity when we were standing in front of the bikes at the dock. I’m the kind of person who likes to do research before giving my seal of approval for certain activities. Especially when I have concerns about my safety. Because you go out into the open ocean, saying I was freaked out when I realized what we were about to do was an understatement. I was very afraid and nearly backed out.Thankfully, Damien the owner has the patience to deal with customers like me. Despite my many negatives thoughts and comments, he kindly and thoroughly explained every aspect of how to use the bike. He demonstrated how to safely get on and off the bike, how to steer, and communicate if we needed to return to the pier, etc. He also provided life jackets.Once on the water, it was great. I felt really safe and had a wonderful time. I laughed and joked more times than I can count, and had forgotten how afraid I had been previously.I highly recommend this to activity. It’s a wonderful experience that will help you step outside of your comfort zone.

Damien is such a wonderful host from the begging to end. Riding on the beach was definitely such an amazing , peaceful , & fun experience. Go out there and live life to the fullest and experience the breathtaking view on shore also !


The instructors were super warm and welcoming for our first time answering all of our questions. We got to ride underneath the bay bridge while also encountering curious sea life such as seals. It was a beautiful experience for locals or anyone just visiting. Definitely coming again to bring more people!

It's a must do activity if you visit the city and Damien was a great guide !!! Saw a curious baby dolphin, seals, sea lions and lots of birds! The bay bridge view was spectacular 🥹 …


Amazing experience! Must try. We took our daughter for her 11th birthday and she had a wonderful time! Damien was such a pleasant guide. Loved it! Another wonderful memory with my family.


What a fun experience! Definitely a workout but such a unique way to enjoy the sfo bay and downtown area! Damien was such a good time and gave so many amazing recommendations to out of town visitors like me and my husband! Definitely recommend if you’re looking for a nice gift or group activity!


I cannot wait to go again. Everybody should add this on their San Francisco bucket list. Damien is super high-energy and so positive. Instant mood booster just being around him! He was super patient with all of us, took pictures for us to enjoy afterwards, and had a killer playlist to rock out to while on the tour! I cannot say enough positive stuff about the experience. You have to try it!
