Since much of what there is to do involves being outdoors, the best time to go is when the weather is mild.
In a southern state, summers can be uncomfortable if you’re not from a similar climate.
The heat is humid, like being in a sauna.
Therefore, you might want to plan for spring break or Labor Day weekend.
Basically, March through May and September through November.
If you do go during the summer, be sure to bring essentials to stay cool and plan fewer outdoor adventures.
