My daughter, Michelle has been living in Homer, Alaska for a year.
She has a small cabin on the beach. It was pretty cold and overcast most of the time we were there, but at low tide (about 9 pm), it was fairly clear and so I went out and walked the beach.
I was rather shocked to learned that driving a vehicle on the beach is permitted. It was annoying. I was all set for a peaceful stroll, and there were teenaged boys joy riding around in circles on the beach!
