Notes:
Clarke Beach Park is a Mercer Island waterfront park on the south end of Mercer Island. It has all the amenities you'd expect from a big park including: a large parking lot, restrooms, paved walkways, both shallow and deep roped-off swim areas, and a dock. There's even 'amphitheater' style steps leading down to the water! And, to top it all off, the water in the deep area has enough depth that the stony bottom is more friendly to your feet.
