Hint

Intro

The trail snakes alongside the famous Tremola road down to Airolo. The skilfully-built bends have been immortalized in countless films. En route: spectacular views of the Leventina Valley with extended motorway entry and exit points.

Description

This stage begins on Switzerland’s most important Alpine pass at over 2100 m. The scenery at the top is unforgettable. No wonder it is jam-packed with tourists during the summer months. Some take selfies at the sparkling mountain lakes, while others step back in time and visit the national St. Gotthard Museum or the Sasso San Gottardo defence installation. Few people know that the Gotthard Pass is also an important water divide with the sources of Rhine, Rhone, Reuss and Ticino all within this area.

Just a couple of minutes on the historic mule trail and the clamour is behind you. Heading south toward Airolo you pass the Chapel of the Dead and then the partly paved mule trail meanders down and across meadows scattered with rocks. Soon you will spot the world-famous Tremola road. The landmarked mountain pass is one of the highlights of today’s hike. It descends 340 altitude meters through 24 turns. Post coaches used to clatter down the road in the olden days. Now it is popular with mountain bikers and motorcycle riders. The hikers are very close to this impressive structure, which is perfectly embedded in the terrain. They cross this awe-inspiring road with retaining walls of as much as 8 m multiple times and in some places they even walk on it. Mother Nature is also part of the scenery: while the roar of an engine might occasionally disturb the peace, you will also hear marmots whistling nearby and if you pay attention, you’ll even see a few away from the road.

The upper part of the route is all about the old road and the muleteers, but the second section represents a different time. You see the Gotthard highway down in the valley and the new road across the pass. Crossing under a viaduct brings the former Motto Bartola defence structure into view, now a Swiss Army base. A narrow mountain trail leads past it and continues through meadows and short forest areas. The last section of the path down to Airolo offers a fantastic view of the Leventina Valley and the surrounding mountains. The trail passes through the lovely old town centre with its winding lanes and heads for the train station below. Airolo is a crossroads of traffic routes from different eras: the old 13th century mule track, the old railway tunnel which opened in 1882 and the Gotthard road tunnel, built approximately 100 years later. A monument by artist Vincenzo Vela near the train station honours the workmen who died during the construction of the railway tunnel.

An enjoyable tour includes the careful planning of the same. Please inform yourself in advance at the local information center about the route and weather conditions. Depending on the season and weather conditions, this route may be blocked or interrupted
