Before the construction of the tunnel, both passes from Splügen, the Splügen Pass and the San Bernardino Pass passing under Einshorn were similarly important but nowadays only one of them, San Bernardino, is open during winter. In ancient times, Splügen Pass was the more important connection. Thanks to its lack of importance it is now a quiet pass where essential portions of the historical roads and paths have survived allowing a good historical review for hikers on Via Spluga.
