Make a trip up to Mt. Washington and stop at Bonjour French Bakery on Falls Road, then go across the street to Lake Roland. There is always parking at the light rail station and it is a pleasant (short) walk down the boardwalk into the park. There is a very well maintained playground at the top of the hill. My nephews love it and always make a few new friends. We like to end the afternoon with lunch at Pepe's and a trip to The Ivy Bookshop since they have a nice section of books for kids.
