“A great location to spend a night car camping. The lots were well kept, easily accessible, and gave a breathtaking view to wake up to. The sites have running water nearby and a full bathroom and shower room. While car camping might not be for everyone, this is a great place to test if it’s for you.” – Brogan, Google Review
