Riverdale Park is a small suburban neighborhood park close to my home, and one which I happen to be very fond of. As a fan of the park, and of suburban "pocket parks" in general, I have placed two caches here to try and get more people to visit this little hidden gem. It's a nice park with ground-level views of the Charles River and the historic Havey Beach Reservation. There is also a small playground, so bring the kids along! This is an excellent spot to watch the annual Run of the Charles Canoe Race, held annually in April. Be sure to say hello to the Canadian geese which have made this park their home for several generations! (And be careful to not step in their... leavings.)
The park offers a nice view of the Robert Cawley Memorial Bridge, which is one of the four bridges connecting this neighborhood with the rest of the world. The area you currently find yourself in is called Cow Island, and it is literally an island, being surrounded on three sides by the Charles River and on the fourth side by a small man-made canal near the Dedham/Needham border. The arches of the bridge are historical and quite ancient, and were only discovered after bridge repair work which was completed in 2001.
On-street parking is available on the park side of Riverside Drive. The park is also accessible via MBTA bus routes 36 and 52. Please note that the park is closed at night.
Congratulations to foragess for being the first to find this cache!
