I live in Aruba and I snorkeled this site a few weeks ago. I entered the water at Catalina Cove and snorkeled to Arashi (heading roughly north) and then all the way back to Boca Catalina. The entry at Boca Catalina is much easier than at Catalina Cove as there are lots of rocks and pointy things you don't want to step on at Catalina Cove. The entry at Boca Catalina is just over white sand. Boca Catalina is a small but beautiful beach where visibility is usually pretty good. There are also no waves or current at this site. Sadly this is a bad snorkeling site as there is very little to see here. I went all the way out where the water was about 15/20 feet deep, but the only coral I could find were some dead tube sponges. There is a lot of seaweed at this site but not a lot of fish. On the positive side I saw a 4 foot long trumpet fish (I never knew they could get this large) and a 4 foot long eel. This site might be good for learning to snorkel, but experienced snorkelers should skip it. If you do decide to snorkel this site, don't forget to also head roughly north to Catalina Cove and Arashi (both are nearby and I consider these 3 sites one large site) where there is much more to see. I'm also a scuba diver and unless I missed something (and I don't think I have), this site is of no interest to the scuba diver.
