So secluded and amazing. We spent two nights here at the end of April, definitely got into the 20s/30s at night so be prepared. We took the Hartnet road north from hwy 24 and crossed the river Ford. Our Subaru Forester did fine but a 4wd vehicle is definitely needed. The dirt road is long so be prepared for about an hour to get there from 24. The Polk road access is closed during winter so call the park hotline ahead of time for road conditions.
