Like all fair-size Swiss lakes, Lac Léman is crisscrossed with comfortable and reasonably swift steamers. In summer they sometimes run more often than the trains that parallel their routes. With a Swiss Pass you travel free. You can embark and disembark freely at ports along the way. The trip from one end of the lake to the other will take the better part of a day as routes are designed to serve a third of the lake per circuit, connecting towns on both the French and Swiss sides. Shorter trips like the one from Lausanne to Vevey will take an hour; the crossing to Evian les Bains in France is only 30 minutes.
