Camping in Yosemite in March

If you are just planning to visit the valley and are not an experienced cold weather camper, I would recommend looking at staying at Curry Village (temporarily renamed Half Dome Village) instead. They have both heated and unheated tent cabins, which are wooden platforms with insulated canvas sides and beds inside. They come with sheets and piles of wool blankets. All in all it is pretty similar to the valley camping experience and will actually probably be cheaper for you if you are looking at buying winter gear for this trip.

The reason I don't recommend camping for you if you don't know what you are doing, you probably won't have a great time. You'll lose a shocking amount of heat to the ground if you don't have a very good sleeping pad and bag. It can be nearly impossible to get dry if you aren't very careful about how you use your outside vs sleeping clothes. Granted, Yosemite is a relatively safe place to get in trouble as there are people who can help you everywhere, but needing to get help is undesirable for a vacation.

All that said, winter is my favorite time to visit Yosemite. Everything looks spectacular covered in snow. The crowds are gone so you can actually quietly reflect while admiring Yosemite's wonders. Glacier Pass in particular is worth a visit for some downhill or cross country skiing which you can't do at all in the summer.

In my experience and opinion, sleeping outdoors in below-freezing weather can be pretty miserable. Certainly there are people who enjoy it, but if you've never tried it you don't know if you're one of those people. Don't bet your entire vacation on an unknown like this.

Find a way to spend at least one night sleeping in similar camping gear in similar weather, prior to your vacation. This should tell you whether camping is the best idea for you for this trip. Make sure you do this within walking distance of your car, so you can bug out early if your feet start to freeze in the middle of the night.

Good-quality winter camping gear can be a considerable investment, so it may be more economical to rent gear instead of buying. Even if you plan to do more camping in the future, you may not want heavy winter gear for that. Invest in the gear that you will use most often, and rent the expensive specialty gear only needed for a single trip. You can rent camping gear from REI, and possibly other retailers. And you may have a local outdoor or hiking club that will help you find equipment to rent or borrow.

My girlfriend and I camped at Hodgdon Meadow last year in May, we had very colder weather and snow. During the day the temperature at the upper elevations went as low as -10 Celcius with a cold wind and light snow. Overnight it probably went down to -20 with freezing rain. However Hodgdon Meadow is at ~7000 feet elevation, down in Yosemite valley proper it was a warm 10-15 degrees and clear skies.

Given that this was several months after the proposed camping date of March, Definitely be prepared with winter tires and chains for driving into the valley, the roads into Yosemite are narrow and very winding, you would not want to have your vehicle sliding about. Also, as the elevation changes make drastic changes in the weather you should know the elevation of your campground. If you're higher in the mountains around Yosemite you will surely experience colder temperature and more snow than if your campground is in the valley. In either case though be prepared for very cold weather camping in March.

In terms of gear aside from the winter tires and chains, keep in mind that Yosemite campgrounds warn of hantavirus, to avoid it its recommended that you keep some space between yourself and the ground. You will certainly want to make sure your sleeping mat has a high R value, likely at least 4 if not 5+, to insulate you from the frozen ground.

March in Yosemite is considered winter, so you need to be prepared for cold temperatures and for snow. A sunny but cold day in the snow can be gorgeous and fun, but you have to also be prepared, so if the weather turns, you won't find your self in a situation where you are struggling for survival.

Trails on the valley floor may be open, but the high trails and roads will almost certainly be buried in several feet of snow. Taking snowshoes might give you more options, but if you are new to backcountry snowshoeing, you should look into a guided trip.

I have never been to yosemite so I cannot answer about this part based on experience. There is however a question about backpacking in april which suggests that there will be still a lot of snow in March. If you consider this enjoyable is a matter of personal opinion. I personally probably would only enjoy this with a warm and cozy camper van, but others like camping in the cold. However, I would not really recommend a beginner camper to start camping in the snow

For the camping equipment, the basics are a tent, sleeping bag and insulation pad. Per group you also need a camping stove and a pot. Everything else is bonus and for comfort. What you take will strongly depend on the type of camping you do. If you are camping out of the car, weight and space are less of an issue and the trade-off will go towards comfort. Examples of my camping gear are a big and roomy tent (standing height rocks, although not necessary for beginners), a camping chair and a table, the 20cm air mattress (great for leveling uneven ground). In colder conditions putting a hot water bottle to warm up your sleeping bag is absolutely great. Maybe you could add a solar shower and a cooler box. If you are on a multi-day hike and have to carry all the equipment, you would most likely not carry any of these things.
