We have been there multiple times..both the State and the National parks. When the winds are coming from the west the bugs are fierce on both sides, bay and ocean. When the winds come from the east the flies/mosquitoes are much more tolerable and stay mostly over the water/grassy areas on the national side (the west side). As for favorite park for camping itself there is only one loop that has electricity and that one fills up a year early. Bath houses have all be refurbished on the state side within the last 2 years. Bath houses on the bay side consist of cold showers, and outhouse type facilities. We didn't use them so not sure exactly how clean/efficient they are. There is a beautiful area on the bay side where you can launch you kayaks or paddle boards. They also have ocean swimming. Oh yea, don't forget the ponies...they all over both sides. Either way, you will fall in love with the place. Have fun!
