Connemara Conservancy, Allen, Texas, has changed a great deal in the twenty-three years I've been visiting. It used to be way on out there in the country, and always open. Hours are limited now, but it's still a fabulous place.
Spring Creek Trail in Richardson, TX, has a trailhead and parking at the southeast corner of 75 Central Expressway and Renner Road. From there one can head in either of two directions. One way goes under the expressway and northwest to an amazing urban wilderness under the interchange of 75 and the George Bush Tollway.
The other goes into a shady system of trails with surprising butterflies. These trails are paved sidewalks, and connect to other trails in the Richardson system.

God make me receptive and aware:
restore to me my capacity to wonder.
