The vibe at North Pines Campground
Drop some North Pines Campground knowledge on us.
Stayed here mid-May for one night - though I was angling for one of the riverside spots (#520 - 526), I was very happy with #515, which is only 30 - 40 ft away from the Merced River. There's plenty of flat ground space for at least three 2-person tents, though you won't get much privacy from other sites. But hey, if you wanted privacy, you wouldn't be camping in a Yosemite Valley campground :)
Avoid any of the sites near the bathrooms - there isn't much in terms of trees / bushes as a buffer.
