Nordic Trail Blue Loop is a 9.3 mile lightly trafficked loop trail in the Kettle Moraine State Forest near Whitewater, Wisconsin, that features a lake and is rated as moderate. The trail offers a number of activity options.  It is close to, but different from, the John Muir Blue Loop. This route has a Strava segment, and people should beat the Strava times if they want to set an FKT.

The route goes from the coastal town of Sitges and finishes in Canet de Mar, forming a semi circle around the Barcelona metropolitan area, and is known as the Sender dels Miradors o dels Parcs Naturals. It passes through the natural parks of Garraf, Montserrat, Sant Llorenç del Munt i Serra de l'Obac, Montseny and Montnegre-Corredor and despite its proximity to Barcelona, it has exceptional natural beauty and feels like a world away from the city.
