Arlington-Arkwright Dog Park 25. June 2014 Adam Urban Adventures (4) This Sunday Henry and I went to one of his favorite places in St. Paul, the Arlington-Arkwright Dog Park! This approximately 4.5 acre dog park is located at the corner of Arlington and Arkwright in St. Paul. The park features a large open area covered in wood chips that is perfect for playing fetch and doggy wrestling matches. There are also trails crisscrossing the woods throughout the park for walking or running with your furry friend!
