Secondary highways parallel the expressways, but this is one case where, as the larger road sits higher on the lakeside slopes, the views from the expressway are often better than those from the highway. Be sure, however, to detour for the Corniche road views between Lausanne and Montreux.
Parking within cities and major towns is difficult and zone restricted. Although expensive, opt for public garages that are clearly signed whenever possible. Take the ticket with you after entry, as payment is made via automated machines at the pedestrian entrance; many locations accept credit cards. The ticket returned after payment is your access card to exit.
