Yes, they are all very cool and worth the drive. But I do have my favorite State Parks near Dallas lol! They are marked with starts along the post, but for a quick glimpse these are the ones I would highly recommend you visit and why:
Eisenhower State Park
Has a stunning lake beach (really, impressive) and an amazing camping area overlooking lake Texoma.
Dinosaur Valley State Park
Real dinosaur footprints along the riverbed! Oh, and a gorgeous crystal-clear river framed by sandy beaches. And a great trail system as well.
Lake Whitney State Park
Crystal-clear lake, with beautiful beach areas. The lake bottom is made of limestone, what prevents it from being muddy as other lakes – under the right weather conditions, of course.
Lake Mineral Wells State Parks
Top-rated trails, rock climbing and unique Penitentiary Hollow rock formation.
Tyler State Park
Tall pine trees! It’s a landscape you wouldn’t expect to find in Texas, specially so close to Dallas. The fall foliage reflecting in the lake there is beautiful. Shady trails and water activities, such as swimming and paddling, make Tyler a local favorite under the Texas heat as well.
