I asked Perplexity AI.

A better list than I expected to get from Artificial Intelligence:

• Tour du Mont Blanc: This hike takes you through France, Italy, and Switzerland, and offers stunning views of the Alps 16.
• West Coast Trail: Located in Canada, this hike takes you through rugged terrain and offers views of the Pacific Ocean 16.
• Laugavegur Trail: This hike in Iceland takes you through a variety of landscapes, including glaciers, hot springs, and volcanic terrain 1.
• Greater Patagonian Trail: This hike in Chile and Argentina offers views of glaciers, mountains, and forests 2.
• Tongariro Alpine Crossing: This hike in New Zealand is considered by some to be the best single-day hike in the world, and offers views of volcanic terrain and stunning landscapes 3.
• Kjeragbolten: This hike in Norway takes you to a boulder wedged between two cliffs, offering incredible views of the fjords below 3.
• The Great Ocean Walk: This hike in Australia offers views of the Southern Ocean and the Twelve Apostles limestone stacks 5.
• GR 20: This hike in Corsica is considered one of the toughest in Europe, but offers stunning views of the island’s rugged terrain 6.
• Banff Highline Traverse: This hike in Canada offers views of glaciers, mountains, and alpine lakes 6.
• Rakiura Track: This hike in New Zealand takes you through forests and along beaches, and offers views of wildlife such as kiwis and penguins 2.

A mixed assortment, of course. It’s difficult to compare an easy day hike like the Kjeragbolten to the Greater Patagonian Trail.
