I did this round trip again yesterday. I didn't go as far as this summer. The last 5-10 miles is too hilly and I was in a hurry. I did my turnaround at Marconi after going in the ocean - yes all the way in. The changing room, bathrooms and outdoors showers are still open and working - just no lifeguards!
I hope to try it again this year - but if not definitely next summer!!!
