The UTDS is a 158 km long trail with D+4200 through the forests of the Ardennes, in the south of Belgium. It's called the UTDS because it runs through the different places where there are water sources, like Spa. It is a combination of parts of the different trailroutes that run throught and around 7 'trailheads' in the Ardennes: Jalhay, Theux, Spa, Stoumont, Stavelot, Trois - Ponts and Malmedy.

Sandakphu - Phalut is a very popular trekking route in India (on the boarder with Nepal), which starts from Maneybhanjan & ends at Gorkhey. Another option is to go from Maneybhanjan to Sandakphu and back.  Both routes are about 60km.
