The Backyard Park in Manvel is such a fun playground to drop by on a weekday where you just need to get the kids out the house. There are plenty picnic tables to take a break and have lunch. The play structure and swing set is appropriate for ages 3+, however you can still bring your little ones to explore and enjoy the small roller slide. The biggest attraction is certainly the zip line which provides hours and hours of fun.
Pack a potty in the car as there are no restrooms. Parking is also very limited. Please be considerate of residents.
