A day ticket can be purchased at the camp site reception which allows you to use all the buses in Switzerland as well as the river boats, or you can get you tickets on the bus. It takes about 45 min to get to Geneva centre. From here we went to the United Nations Centre by tram which provided a good tour on the UN.
Also from La Columbia you could visit Mont Blanc which is a 1 hour drive away. Mont Blanc has a lovely picturesque town with a good selection of shops and restaurants. Whilst at Mont Blanc you can go up the mountain by cable car or train, if you feel fit enough you can walk up it.
