Half a billion years of continental drift on display — mountains once part of Africa, a Mars-like mantle plateau, and a landlocked fjord with 600-metre cliffs.

Gros Morne National Park is the reason geologists come to Newfoundland. Half a billion years of continental drift is on display here — the mountains were once part of Africa, pushed across an ancient ocean and stranded when the continents separated. It's a UNESCO World Heritage Site and one of the most geologically dramatic places in Canada. Here's the guide.

The Tablelands The park's signature sight — a 600-metre plateau of orange-brown peridotite, the rock of the Earth's mantle, normally found only deep underground. It looks like Mars dropped into Newfoundland. The easy Tablelands Trail walks you across it; the off-trail scramble up gets you the full desolate panorama.

Gros Morne Mountain The park's namesake — an 806-metre peak and a full-day hike (the James Callaghan Trail). The summit loop takes you past Arctic-alpine plants, a hanging valley, and views to the Gulf of St. Lawrence. It's steep and exposed; start early.

Western Brook Pond A landlocked fjord — a 16-km freshwater lake walled by 600-metre cliffs, with waterfalls tumbling off the heights. The hike in is easy; the boat tour into the fjord is the only way to see the full drama. Book it; it's the park's most popular experience.

Lobster Cove Head and the coast Light station, coastal trails, and the fishing history of the area. The Green Gardens trail crosses volcanic sea cliffs and sea stacks.

When to go July and August for the fullest trail access and boat tours; June for icebergs; September for fall colour and fewer crowds. Much of the park is inaccessible or unpleasant in winter.

Good to know It's a four-hour drive from the Deer Lake airport, or five from Corner Brook. Weather closes trails — check at the visitor centre. And this is serious wilderness: bring proper boots, layers, and a plan.
