Two mountain passes lead South from the Rheinwald: the San Bernardino Pass into Misox valley and the Splügen Pass into Val San Giacomo in Italy. The San Bernardino Tunnel (Swiss Highway A13) was opened in 1967 and stays open all winter. Mule tracks on Mount Safierberg and Mount Valserberg connect the Rheinwald with its Northern neighbour Safien valley and Vals. Another trail leads through the Val Curciusa valley via Bocchetta di Curciusa Pass and then connects to the San Bernardino.
