From Jason May, Reef GM:

For those who don’t already know, there is now very easy beach access to the east of Duggan’s.  It’s located roughly 100 feet to the east of Duggan's rear kitchen area, past the maintenance shed and sewer plant. We widened the existing trail for ease of use. I believe that this is a much more enjoyable beach to walk than the "Reef Beach" on the west side of the restaurant.

Enjoy!
