The Ruby Jack Trail is a beautiful rails to trails course on the Ozark Plateau in Southwest Missouri. The 16 mile trail runs through the small towns of Carthage, Oronogo, and Carl Junction, Missouri to the Kansas state line. The trail is mostly tree lined, running through oak, maple, and cedar making the trail particularly beautiful in the fall. In summer, much of the trail forms a green tunnel providing shade and windbreak. Spring and summer wildflowers are abundant and the smell of honeysuckle is common. The area gets little snow, so the trail remains passable throughout the winter.

Route starts at Ücia Pederü. It goes up to the hut Lavarella via the hiking path and further on to summit Heiligkreuzkofel and Zehnerspitze (only beginning of the via ferrata, not the summit itself). Back that way to Forcella di Medesc and up to Piz Lavarella via the north face. Some climbing UIAA 1 to 1+ is needed. Both summits must be reached (main and west summit). Further on down the south face of Lavarella to the lake "Le de Conturines" and short before Ücia de Gran Fanes head right (way 17) to the Vallon Bianco. On the crossing you can refill water in a little stream.
