Beautiful campground
I drove up Notch Mountain Rd from Hwy 24 to reach the campground and Holy Cross Trail Head. The road was dirt, bumpy, rocky and has several low dips that would definitely fill after rains, but it was totally passable in my low-clearance 2WD old pickup. There was decent Verizon service the whole way up and at the campground, which was empty on a Tuesday night-Wednesday night. Bathrooms were standard NP composting toilets and sites were spacious with sufficient flat spaces for tents and perfect hammock hanging spots between evergreen trees. Little creek runs along Site 1 and it's very lovely. Used this campground as a base to hike Mt Holy Cross; a challenging but doable hike for fit folks. Use extreme caution choosing when to hike in regards to weather; hikers are exposed for a long time across scree fields and a windy ridge and the final scramble up to the summit.
Parking lot had sufficient space. Only saw 6 other hikers and two dogs, plus our 5 people and dog, during the 24 hours I was in the area, but it was a weekday. Saw 4+ hunters using the parking lot, as well.
