GR10 — The Pyrenees Traverse

The GR10 is a monumental, 866km trans-Pyrenean thru-hike that traverses the entire length of the French Pyrenees, from the Atlantic coast at Hendaye to the Mediterranean at Banyuls-sur-Mer. Widely regarded as one of Europe's most demanding long-distance trails, it follows established paths through the high-mountain landscape, crossing numerous iconic passes and dipping into traditional mountain valleys. The journey typically requires 50 to 60 days of sustained effort and is known for its extreme physical attrition due to the constant vertical shifts between valley floors and high cols.

Subarctic Wilderness Reserve. Hornstrandir is Iceland's most isolated and magnificent wilderness. Located in the extreme northwest corner of the Westfjords, just miles from the Arctic Circle, it was completely abandoned by human inhabitants in the 1950s. Today, it has no roads, no shops, no permanent residents, and zero cell phone coverage. It is accessible only by a scheduled boat across the Ísafjarðardjúp fjord. While the reserve is a modular trekking area with various fjords, a common 4-day traverse runs approximately 50–60 km between Veiðileysufjörður and Hesteyri (via the Hornvík bay), crossing steep mountain passes and dropping into stark, isolated fjords. It is a sanctuary for the Arctic Fox and features the awe-inspiring Hornbjarg bird cliffs.
