If you want more of an adventure from your Lake Como holiday, then why not go on a cycle tour from the UK (via the ferry/train) to mainland Europe and make the most of your journey from start to finish. This can be one of the most enjoyable experiences of seeing Europe and keeping fit at the same time. A fantastic sightseeing experience through various countries as well as taking in the magnificent landscapes at your own leisure. This is a very economic way to travel and will cost you less for ferry/rail tickets.
You have the choice of planning your own route and accommodation with help via the internet enabling you to take the journey at your own pace or alternatively, you can pay for a cycle tour package along with a guide. Many of these tour packages follow an itinerary with plenty of stops in order to give you a chance to see the country you are in and also to recharge your batteries for the next leg of the tour.
Many cycle tours require you to have a reasonable level of fitness and plan routes to be enjoyed rather than endured. The more advanced cyclists can find routes that take them through the Alps and more challenging landscapes.
Please note that it is advisable that you have holiday insurance cover, especially for this type of travel.
