Hidden Cove is the best park I saw on Lake Lewisville, Texas
I stayed at several campgrounds on Lake Lewisville, but I Hidden Cove was the best. It has a huge marina and restaurant. The campsites are pretty and have a decent amount of room. The bathrooms are not all conveniently spaced but overall it is a nice campground.
One of the things that sets it apart from the other campgrounds is that there are several cabins that you can rent. They are basically structures that keep you out of the elements, but it is a good place to set up a cot and have a nice night of sleep.
There are rentals for kayaks, paddle boards, etc. If you like camping and enjoying the Lake, go visit Hidden Cove.
