Imagine standing at the base of a ski jump so enormous that athletes fly over 200 metres through the air at speeds exceeding 100 km/h — that is exactly what awaits you at Mamutí můstek in Harrachov. This ski flying hill is one of only five fully functional hills of its kind in the entire world, and it sits dramatically on the northern slope of Čertova hora ('Devil's Mountain', 1023 m a.s.l.) in the Czech Giant Mountains. Locals affectionately call it 'Čerťák', and once you see it towering above the village, you will instantly understand why it inspires such devotion.

The hill blends into the forested landscape of the Krkonoše range beautifully, and visiting in any season offers something special. In winter, the snow-covered slopes frame the massive in-run tower in a truly cinematic way. In summer, the green hillside gives you a better sense of the sheer scale of the construction — the in-run alone is 122.5 metres long. A single-seat chairlift once carried competitors up to the starting tower, and it remains a striking detail of the site.

• Harrachov town centre — the hill is clearly visible from the village; easy walk of approximately 15–20 minutes, flat to gently uphill, easy difficulty

• The hill has been closed to competition since 2014 due to structural damage; reconstruction plans are underway
• The official hill record is 214.5 m, jointly held by Finland's Matti Hautamäki (9 March 2002) and Austria's Thomas Morgenstern (9 January 2011)
• Construction point: K185, HS 210 m

Harrachov made sporting history in 1996 when the 200-metre barrier in ski flying was broken here for the very first time in an official competition — a milestone that cemented this small Czech resort's place among the legends of winter sport.
