Great RV Park - but expensive
This RV park is actually a resort in itself as it has three swimming pools, a large soccer field, basketball hoops, bocce ball courts, water splash area for kids, etc. it also has a small outdoor restaurant that serves pizza and chicken wings and a full-service General store. Lots of stylized cabins are also available. Only about 3 miles from Solvang. The only negative is it can be quite expensive but I guess supply and demand takes care of that.
