It was easy to find the office on the pier and was directed to the location of the submarine. The guides were very personable and knowledgeable. Made the trip through the waters very enjoyable. Seeing the forest of kelp and thousands of fish swimming around the sub's windows was a great experience, especially when there was context coming from the guides. Definitely would recommend to check out if you are interested in wanting to check out the ocean around Catalina Island (such as seeing bottom glass boat ride or submarine tour).
