If you are taking your RV to the Northern Peninsula, we'd recommend you set up at Viking RV near Quirpon. The campground is just off Route 436 which is part of the Viking Trail. It's only another 6 km to the National Historic Site at L'Anse aux Meadows.
Viking RV has approximately 40 serviced sites, both back-in and drive-thru. The sites are gravel and level. Most sites include a grassed picnic area. The park is located on a small pond. It's not uncommon to see moose in the area. We visited in early June after an unusually bad winter. You'll see by the photo above, we still had snow in the back part of the campground.
Grace is your host, she runs a great campground and will help direct you to local attractions. Grace also runs a small diner at the campground where you can get breakfast or a mooseburger! Grace also makes home-made pies.
The washrooms and showers are newly renovated. They are the nicest we've seen at an RV Park. Electrical and water hook-ups are new and well maintained.
Viking RV is about 320 km north of Gros Morne National Park. It's about a 4 to 5 hour drive with a trailer. Route 430, the Viking Trail is a good road. It's a beautiful drive that follows the west coast of the island. You have the Gulf of St. Lawrence on your left as you drive north and the Long Range Mountains on your right. Viking RV is just off Route 436 (the road into L'Anse aux Meadows). It's about 25 km north of the turn-off from Route 430 to St. Anthony.
