A five-hour layover provides ample time to leave the airport and experience a brief taste of Switzerland. You can board the efficient underground train from the airport station and arrive directly in downtown Zurich in just 10 to 15 minutes. Once there, you can take a brisk stroll through the historic Old Town, admire the views along the Limmat River and Lake Zurich, or sit down at a local café to enjoy authentic Swiss chocolate and pastries before returning.
