Rent bikes - A great way to see the sights around Geneva is by bicycle. Rental bikes are available at the train station or even better - borrow one for free during the summer (up to four hours) from Geneveroule, which has bikes of every kind, including those with baby trailers, child seats and tandems. Free rentals May to October, pick up the bikes at Geneveroule on Quai du Mont-Blanc at Paquis.
Parc Mon-Repos - This is a lovely green park, right on the lake, with a children's playground. There's a Mouette stop (De Chateaubriand) for the line which goes across to Geneve-Plage on the left bank.
Botanical Gardens (Jardin Botanique) - Geneva is a city full of both large and small green spaces to explore and enjoy with children. Don't miss the animal park, with its collection of over 300 species, including deer, ducks and flamingos, plus an aviary full of exotic birds. Kids enjoy a ride on the magical two-story Carousel of Fables, which rotates in opposite directions and features such whimsical animals as a flying fish, a stork pedaling a tricycle/baby carriage and an upside-down lion.
Visit the United Nations - The United Nations offers hour-long guided tours of the complex, called the Palais des Nations, in English. Watch a film, learn how the UN's predecessor, the League of Nations, came to be formed and see the chambers where decisions of worldwide importance are debated.
Ariana Park (Parc de l'Ariana)
, where the Palais des Nations complex is located, is a great location for kids who need space to run around. It has vast grassy lawns, shade trees and roaming peacocks.
