The best kept secret in Dallas must be the Katy Trail. This 3.5-mile pedestrian and bicycle trail system runs through downtown, and the trail offers stunning views of the city. There is a concrete path as wells as a soft recycled-rubber track for runners. It’s the best place to take your dog for a walk and see Dallas as the locals do. The trail is kept immaculately clean, and it truly enriches the city.  - Jordan Dietterich of Surfside, Florida
