Believe the park's website when it states "the biting gnats have hatched"! We gambled, thinking the ghats would not be so bad, however, they were bad even with head nets on! The island is beautiful and the scenery spectacular. Did not see enough buffalo or deer though. Saw plenty of gnats. The campground is excellent also, had to go down the road for the shower, but nice. Would return, but not in May or June!
Manicured RV park. Excellent bathroom/shower. Perfect spot when visiting Bryce Canyon NP, Zion NP, and even the North Rim of Grand Canyon. Excellent restaurant across the street, "The Adobe". Stayed 2 nights and would definitely return.
