An "Off Road Vista" bike journey. Follow the Bronx River bike path through the Park while parralleling The Bronx River Parkway up to the dam and back. It's 35 miles of the most beautiful scenery. At this time of year, migrating birds, fresh Spring flowers and babbling waterfalls are an absolute delight. It's a mostly paved path with some riding in traffic as well some easy hilly places. To make it perfect, we'll lunch in Heaven. Or, at least that's what the Nordic name implies, Valhalla. Bring a Metro North bike pass, just in case and money for lunch.
