I come up the hill from CSH and go right in the front way. No one there to question or stop you. The first time I went in there were other cyclists there - luckily as they guided me out the back way. It is an impressive spot - gorgeous views of the harbor, interesting architecture, sculpture, and way to take a break from the rest of the hill on 25A. Of course you pay the price coming out the back, but it is a long, steep "driveway" of a road as compared to the busyness of 25A. And looking at the map there a number of ways to get up and over to Sagamore and then over to Oyster Bay. Definitely try it.
