We tend to spend most of our time at the State Parks. It is less crowded, and there are tons of fun things to see and do.
Myrtle Beach State Park is the closest to the house and is fairly isolated, giving the impression that you aren't "in town":
Huntington Beach State Park is another local park that is a ton of fun. They have a Nature Center, marsh lands, and a beautiful beach. Unfortunately while we were there, it was POURING rain, so we didn't get to do as much as we normally do.
We also went to "Broadway at the Beach" and while we were there this summer, Lego's Brickation was there! The kids (and cute hubs) had a blast!
The boys also decided to go in a fountain while we were there... I told them it was only ok IF they didn't get wet... they listened REALLY well.
We also went to Barefoot Landing.
All in all, it was an awesome trip, and we can't wait to go back again!
