Make sure you get to Yosemite just in general. That is the first thing.
The Lower Pines Campground was great. It was further back from most of the other campground and had fewer spots available. Because of the location and the number of spots, it was a pretty quiet area.
The views were out of this world. Beautiful starry nights showed brightly through the canopy of trees. Waking up every morning to the sun rising over the mountains. EXCELLENT views of the mountains.
The bear boxes were more than adequate. We fit an RTIC 45 cooler and still had 75% of the bear box available. The bear box was also tall enough to make a nice cooking surface. The was enough room on top to hold our stove, dishes, meal prep, etc while I cooked each meal.
The Rangers were nice and helpful.
The bathrooms were only toilets and sinks (no showers), so be prepared with a plan B, plan to shower when you go back home, or expect to pay for a shower. The bathroom was clean and adequate.
The fire pit was great and considering the park does not allow outside wood, the wood bundles were not overpriced in the general store. The general store was full of things you didn't know you wanted while camping (including microwave food). Lot's of meals, snacks, drinks, toiletries, cleaning products, souvenirs, and camp essentials.
There was no WiFi on the campground (that's the point, right), but free WiFi was a short drive away in the Village, making it possible to check and follow up on those work emails that couldn't wait.
Attractions are a short drive away, most being an hour or so. And plenty of hiking to choose from.
We stayed in an RV for 3 nights in Lower Pines an experienced torrential rain for 24 hours followed by hot sunshine the next day. The site doesn't have any hook up facilities (electric, sewage or water) and the on site toilets are basic, to put it mildly. However, there is a dump station and a facility to top up your RV water level. These facilites are both free
Despite the lack of facilities, the site is in a lovely location, set amongst trees, in a quiet spot (limited use of generators allowed) and is in an ideal place for walkng amongst the magnificent secerely that is Yosemite. Each pitch has lots of room and has it's own fire pit and table/chairs.
Would highly recommend, especially at such cheap prices. However, choose your pitch carefully as some do become flooded if the rain persists.
We spent two nights here in an RV, and it was lovely. Getting a pitch is a minor miracle however and you will have to work out very carefully when booking opens and book within the first minute to get one as they are limited and in high demand. Once you've got over that hurdle your next one is to actually find the campsite when you arrive in the park. There no signs for it anywhere in the valley. We'd programmed our GPS to get us to the junction we knew it was on but once there we had no clue. All we could see were signs for Curry Village. Eventually, after driving around for a while, we found someone to tell us to follow signs to Campgrounds, but that was not much further use as there are three 'pines' campgrounds. Really, would it be too much to ask them to put up some signs?
When we got there, we were rather pleasantly surprised to find that as we had an RV we didn't need to use the bear box. This was good, and less hassle than I was expecting. From Lower Pines its an easy walk to Curry Village - but first you have to find your way because again - no signs! Curry Village has lots of facilities including a bar and supermarket, but the Wi-Fi room is useless, some people were trying for up to an hour to get on the internet. Sometimes we could connect but it wouldn't actually let us do anything.
Anyway. Lower Pines Campground is set into the trees. There is plenty of space in each area for the RV, and a picnic area, a bear box and a fire pit, and we even had space to put our chairs out. It was a little bit noisy at night when people didn't follow the quiet-time rules, but other than that we enjoyed our stay.
Camping in Yosemite on Memorial Weekend had me nervous. I selected Lower Pines because I wanted a small campground than some of the others available in the park. I did my research and had an idea of what camp site I wanted in particular. I sat at the computer the day the reservations for that period went live and was lucky enough to get the site I had selected (site 71). It was a great site. We backed up to a patch of woods which bordered the meadow so no one behind us but deer and birds. The site was large enough to have friends of our pitch their tent (we had a pop up camper) and still have room to move around and park two vehicles. I didn't feel like we were on top of neighbors, but the sites along that outer loop definitely had more room. None of the sites have any hook ups. The river was just a short walk across the camp ground so it was fun to hear that throughout our stay. In one direction we could see Yosemite Falls and to the other we had a good view of Half Dome. The camp ground was full, but it was quiet. Each site comes with a bear box which was large enough to fit a large cooler and two smaller coolers, plus all our other food and items. You have to put everything with a scent in the bear box including sun screen, soap, drinks, etc. So keep that in mind when you are packing. We ended up not being prepared for that and we had lots of little items just thrown in there and it was a very tight squeeze! The campground was located within a short walk to a shuttle stop which made it easy to get around. In four days there we only drove our truck once. There was a store and burger place within walking distance. The showers were over in that area too, but we did not use them. The bathrooms in the campground had sinks (cold water only), did not provide any soap or paper towels (assuming because of the bears). There was a sink in between the restrooms for potable water and a dump site for gray water, but there was no actual dump site in that camp ground. You had to go across the street to the Pines campground. There were also no spigots with in the campground other than that one by the bathrooms. I have seen some nasty camp ground bathrooms, but these were probably the worst. I don't know that they were ever cleaned in our time there. I realize it didn't help that it rained for two days and that it was the busiest time of year in the park, but they were really, really bad. We would definitely stay there again. When we looked around at the other camp grounds in the valley, Lower Pines was definitely one of the best. North Pines (across the river) seemed similar, but the other Pines campgrounds were very crowded. It was hard even walking through them because there was so much traffic.
