This classic ultra running gorge loop starts from the Herman Creek Trail head in the Columbia River Gorge. Herman creek and the Pacific Crest trail meet up just south Wahtum lake and are connected near the Columbia River by the Herman Bridge trail. 

The N70 route is a hiking route that opened in 1970 and runs over 8 "peaks" of the push-moraine between the city of Nijmegen and the surrounding polder. It is signposted by light green markers. Mostly forested single-track and uncharacteristically hilly for Dutch terms, this is one of the best places for trail running in the Netherlands. It offers stunning views and runs past some historic sites, including Netherland's thickest tree, a 450 year old chestnut, and a historic boundary marker of the then Dutch-German border.
