Swarm Pokemon

Swarms are located on random routes in all the regions that are available currently. When a swarm occurs certain pokemon will appear. Always look in the top left corner of your screen to see if their are any swarms. If there are then go to the route the swarm is located on. It is reccomended to have beat all the regions before participating in a swarm. This is to ensure you can make it to the swarm almost 100% of the time.
