A little bit of a drive off main road. We booked last minute and so glad we did. Stayed in the B loop site 31 and it was mostly empty. Campsite was large and about 40 yards from the lake. So quiet and peaceful. Vault bathrooms very clean, camp host made their rounds on their golf cart and waved. Friendly.
