What is the best time to visit Sulphur Springs for camping?

May through September is the most popular time to visit Sulphur Springs, when the town hosts several festivals, markets, and an open-air movie theater in its central square. Texan summers are hot, so RV camping might be a more comfortable option, but you can always escape to the nearby lakes to cool off. Camping is possible year-round in Cooper Lake State Park, but spring and fall provide the most pleasant weather for hiking and outdoor activities.
