Rock climbing is an incredible sport and it is even better shared! And yes, most of the time you need to be at least two which is not always easy to organize with friends' timetables, etc.. Which is too bad because there are really great places to climb around Paris accessible by public transport and/or car in less than 1h. Cool places like MurMur, Bures-sur-Yvette, Fontainebleau, and many others in Eure or Seine et Marne. So just check up our group and feel free to post your plans : week-time or weekends alike !
