[B]absolutely can snorkel at eagle beach
but, not much to see.....sand and some schools of teeny fish.
we have found the best snorkeling on eagle and palm beach at the divi phoenix, but it
was just a little better than sand and fish. there were more fish, but no coral formations or anything really pretty.
Above you should be able to find some fish, octopus, etc. There is a little Polis (Police) substation right there on the beach (point of reference- between the Westin and Phoenix). This is a perfect spot on Palm Beach if you just want to do some snorkeling on your own for free
personally, i love catalina cove and boca catalina about a 10 minute drive from the hotels along eagle beach.
Thanks to Andrea J. and ArubaLisa, we found very good repeat very good snorkeling right off the Police station between the Westin and the Divi Phoenix. The trick is that you have to swim around the little island that ArubaLisa showed in the photograph above. We saw a 4' parrot fish and smaller relatives, angelfish, damselfish, and an abundance of striped grunt, sergeant majors, and similar fish. On the inshore side -- only a few. Most were on the north or northwest side of the rocks.
Only you must keep an eye out for the ski boats and (especially) the jet skis.
