Helen's Park might just be one of Houston's best kept secrets. Google Maps doesn't even know about it.
It's tucked in between the Stella Link YMCA and McGovern Library, right behind Sheltering Arms Senior Services. It's not marked on the map, but it's open to the public. Parking is available in the library and Sheltering Arms parking lot, but the park entrance is on Stella Link.
Helen's Park has winding sidewalks, a meandering brook, bright flowers, palm trees, mosaic fountain and huge trellis covered walkways. This park does not have playground equipment and is not for bikes, sports or even picnics (according to the posted rules). It is for "thoughtful contemplation" and visitors are encouraged to "listen to the birds, enjoy the color, follow the brook, walk the pathway, delight in the fountain, rest on the benches, admire the flowers, relax, think, enjoy...".
It's a great spot, right in the middle of the city. Visit the park and then stop in the library for a very enjoyable Houston morning.
