Yes, you can swim at the beach. There is no life guard there, so swim at your own risk. Also, it's about a mile and a half hike to the beach area with plenty of stairs to hike down to get to the beach.
You can NOT get to the beach from the Lion's Den unless your brave enough to climb down the hills. There may be a path that could lead you to the South Beach area were you sure can swim, but I'm not 💯 on the trails heading to the beach as I have yet to explore all the trails there.
You could, but the water is usually quite cold, best for a really hot day.
Would be a little cold now...but absolutely.
