Both metered and free parking is available along the entire stretch of Day Boulevard and near Sullivan's, as well as back a few streets in the surrounding neighborhoods.  

Another awesome feature of this location is that you can actually walk an entire loop around the Carson Beach area.  There are actually several great beaches in Boston that are not only within city limits, but also accessible by public transportation. 

M Street Beach is within sight and a short walk down the stretch, and across from the beach area are large shaded parks to enjoy.  You can usually find a variety of Food Trucks or an Ice Cream Truck on hand during peak months.

It's probably a bit more than a mile full circle with a paved walkway along the rocks. Strollers work well, and little ones can bring a small bike or a scooter, rollerbladers are welcome as well as runners and walkers.
