We recently stayed at OYBC for Labor Day weekend for 2 nights. We booked Site 3 and were very pleased. The campground was easy to get to coming from Bay Area, very clean, and had lots of shade. The downside was we had some trouble finding a flat area to set up our tent and that our site was in the middle of the campground, so you have a little less privacy. Site 1, 2, and 4 were within view. Other than that, there was a bundle of wood waiting for us at the fire pit, two tables (1 with seats and 1 without), and only a 15 minute drive to Bass Lake and 1.5 hr drive to Yosemite valley floor. The bathrooms were clean but were a bit far (located at the front entrance) and you have to walk up and down the treacherous hill. Just bring a portable toilet with privacy tent and you should be good. Trash bin was also located at the front entrance. We didn’t really see wasps, but we did see mosquitoes, ants, and flies. There were not too many, but a screened canopy and traps definitely would help. No sightings of wildlife during our stay. They are not messing around when they say you absolutely need AWD or 4x4 to get in the campground. It’s a fairly steep climb, with lots of gravel, potholes, and uneven terrain. We only wish our site could fit more cars and people so we could bring our friends next time. Perfect camping getaway for singles, couples, or small families!
