No need to put too much thought into where you are going to camp; when you are in a spectacular place, and Zion NP is one, the campsites are spectacular. That being said, #6 on Lava Point Trail is to die for.

Not the most private campground, but good access to bathroom facilities, clean water pumps and just a short drive (or walk) to the Zion Visitors Center where you can pick up your wilderness permits/take one of the free buses into the canyon. There are plenty of deer and other wildlife that are not intimated by the campers and you will often see them roam into the campsite day or night - be sure to safely pack your food away as I did not see any canisters at the site.

The campgrounds were full when I was in Zion, even on a weekday. You will have to arrive early in the morning for a chance to get a spot. Seems like these stay pretty full during the peak seasons.

Zion is one of my "happy places"! Watchman campground is such a luxury for car camping! My first visit here I came during the winter season so I couldn't reserve in advance. The bathroom facilities are very nice and every campsite is also of quality! I highly recommend staying here!

Great area to stay with easy access to Zion National Park. Don't expect to have a lot of privacy, but if you like getting to know your neighbor and sharing trail plans, this is a great place to stay! The visitor center, only a short walking distance away, has drinking water to refill your bottles. When I was there I saw plenty of wildlife, including deer and tons of squirrels! Make sure to store your food away from critters! It get's extremely hot at this campground in the summer, so don't plan on sleeping in or you'll roast in your tent. There are so many great hikes to do in Zion, I highly recommend going! It's also easy to walk into the town of Springdale which has some cute little shops/restaurants! My favorite is Zion Pizza and Noodle!

Zion! Don't go on Holidays!

Spectacular campground! The best we've ever stayed in beauty wise. I don't think there's a site that isn't picturesque. We stayed at site A2. As others have stated, the sites are close, with not much shrubbery between. Some sites are on the Virgin River. No hookups. Generators stop at 10pm. We made reservations, since we were there during the summer. I recommend it!
Bathrooms are modern, flush toilets. No showers. The Visitor Center/shuttle stop is a short walk away.
They do allow pets & you can have a fire (with rules).

Incredible views in one of my favorite parks! This campground is big but has a lot of options depending on how you prefer to camp. Group sites are available for any big adventures but not open year-round. Clean bathrooms but no showers in the park.

Great spot to set up for a weekend in Zion. I highly recommend checking this out during the off-season. I visited in November last year and I had numerous options for camp sites, and there wasn't too many people around me.
