Part of the GTA trail is shared by the blue and red trails of Via Alpina. While the GTA never had significant governmental support, Via Alpina is a heavily subventioned European iniative. It is to be regretted that these subventions were not focussed on supporting existing local initiatives, but creating alternate trails. It remains to be seen whether the net effect of Via Alpina onto GTA is positive (bringing new hikers into the region) or damaging (drawing hikers from Posti Tappa into alpine huts).
In this wiki, shared trails with Via Alpina are prominently indicated so that users can refer to the official website http://www.via-alpina.org for practical information and for alternative connection trails.
