Monts-Valin is THE place you need to go if you want to see Quebec's famous snow ghosts. To access the hike, you will need to reserve your spott on the snow shuttle, which will bring you where the hike begins. You can book in advance through the National Park's website or by calling: 1 800 665-6527. The price for the shuttle is 67$ for adults + the daily park access is 9,85$ per day. You can also do winter camping in this park. The winter camping spotts are next to a beautiful river and are about 1km away from the Visitor Welcome Center. This was one of the first place where I tried winter camping and I highly recommend it, as you are not too isolated if you need any exterior help.
