Dogs are permitted only if they are controlled by a leash and restrained to trails during their visit. This is as much for the safety of the pet as for the protection of the wildlife. Potential hazards to dogs not controlled by a short leash include snake bites and contact with poison ivy. All City of Houston Ordinances regarding dogs, including clean up of waste, must be followed. Pets should not be left in unattended vehicles. Trails are designed for hiking only, no biking or jogging. Enjoy over 5 miles of nature trails, including forests, pond and praire habitats. This 155 acre nature santuary is located on the western edge of Memorial Park. It is open from 8:30am to 6pm daily.
