If you're looking for perfect bounces and ideal lighting, the solitary, hidden tennis court at 10th Avenue and Olive Street might not be for you. But if you want atmosphere, you'd be hard-pressed to find a better place to play a few sets. Encased by beautiful mature, ivy-covered fences, the court was built by the grandfather of Denver tennis doyenne Mary Silverstein in 1891. For the next half-century, the family used it as a private court, as well as a bike-riding training ground and an ice-skating rink. Today it's known to only a handful of locals, most of whom use its undulating surface to ride skateboards and bicycles. Still, if you can find it, it's worthwhile to stop and hit a few strokes, just for the quiet history.
