Visitors to the Bolivian side of Lake Titicaca can stop of at the mystical Isla del Sol (Island of the sun) and Isla del Luna (Island of the moon), taking in spectacular vistas of the surrounding lake.

Part Swiss, part French (where it is known as Lac Leman), Lake Geneva is the largest of Europe's Alpine lakes.
Sailing and yacht clubs for boating enthusiasts abound, but there are also water-borne activities for beginners and thrill seekers.
Numerous sailing schools cater for children and first-timers while the more confident can try their hands at water-skiing.
Those looking to experience the beauty of the lake at their own pace can cruise the 46 mile long on stretch of water stopping of to sample the delights of picturesque towns such as Montreux along the way.
Summer visitors meanwhile can catch a glimpse of the Bol d'Or Mirabaud, one of the most important inland races in the world.
