April 6, 2026, View of Rapperswil Harbor, Old Town, and Castle

The lake on both sides, the city and the castle make for a wonderful panorama. You also forget the very busy Seedammstrasse behind you.

A busy but beautiful route across the dam, partly with a wide cycle path. Unfortunately, the section from Hurden to Pfäffikon on the gravel path is now closed to cyclists (until the first accident happens on the main road).

Wooden Bridge Seedamm-Weg / Route Pfäffikon SZ - Rapperswil SG "A monumental project at the turn of the millennium," inaugurated on April 6, 2001. The narrow passage between Lake Zurich and Lake Obersee has always been used by local residents to cross the water. Until the Middle Ages, this was done by ferry. After Rapperswil was sold to the House of Habsburg-Austria in 1354, Duke Rudolf IV, the Wise, decided to replace the ferry service with a wooden bridge. Completed in 1358, the structure was 1450 meters long and rested on 546 oak piles. It was 12 feet (approximately 4 meters) wide and designed for pedestrians, carts, and livestock. Toll revenues financed construction and maintenance, with the residents of Rapperswil, the monks of Einsiedeln Abbey, and some farmers from the Schwyz territories of Höfe and March being exempt from the bridge toll. The daring structure was also exposed to various dangers. For example, it was repeatedly damaged or even destroyed during wartime events, and natural forces such as waves and storms also took their toll. For this reason, the planks were not nailed to the bridge structure, and there was no railing. This meant that a storm could not tear down the entire bridge; only the loose planks were blown into the lake. Therefore, crossing the bridge was not a safe pleasure for everyone. In 1939/51, the dam was renovated, and the bridges were reinforced to handle the increasing car, truck, and train traffic. A stroll on the dam's sidewalk had long ceased to be enjoyable. Therefore, the idea of a new pedestrian bridge in the form of the old wooden bridge seemed appealing. The new wooden bridge was inaugurated on April 6, 2001. It is the longest wooden bridge in Switzerland (841 m). It rests on a total of 233 piles.

Opposite the harbor mole or at the entrance to the harbor there are beautiful views of the harbor, large parts of the old town and the castle and church enthroned above.
