A path runs south from the Adler Planetarium to this crescent of sand. Despite its proximity to the visitor-mobbed Museum Campus, the small beach remains bizarrely (but happily) secluded. Bonus: if you can't get tickets to see your favorite band at the Pavilion at Northerly Island, you can sit here and still hear the tunes.

There aren't many amenities besides a bathhouse, a taco shop and a couple of picnic tables.
