Another vote for NF; I've been up the Great Northern Peninsula to Gros Morne, St. Anthony's, and Lanse aux Meadows.
Excellent and worthwhile. Gros Morne is where the Earth's mantle has been uplifted to the surface and the elements are toxic to plants, so it's big green serpentine mountains covered with clay; watch it in wet weather. Lanse aux Meadows is magical; imagine Viking ships arriving 500 years before Columbus. And Columbus didn't even construct a settlement in the New World. Columbus Day has always been a joke to me since visiting LaM.
Watch out for Newfie jokes!
