This group is for people that live in Lyon and for travellers passing by, to get some tips about things going on in the city, bars, gatherings, etc.
On the "Lyon Meet-up" group, you'll find out more about the BW activities in Lyon, as that group is dedicated to our meetings and events. Anyone can join and participate.
If you want to create your own activity, please checkout the feature here: http://www.bewelcome.org/activities
See you and enjoy Lyon ! ;)
