The Calendar of Local North Argyll Events will give you a flavour of what might be happening here through the year based on the usual annual events and other activities as I find them.
We have plenty to chose from : Highland Games : Agricultural Shows : Craft Fayres : Sports events : Nature Walks : Cultural and historical days out :

I top it up as other events and activities locally are organised and publicised.
Many local places, groups and organisers use Facebook locally to promote their events :
check out Kintaline House, by Oban page and Visit Oban and Lorn group for the latest news. 
As with every event things can change, so please confirm details independantly.
If you are planning a break in the future, look back to see what might have been on in the previous year at the same time.
If you are looking for something to do, do not hesitate to ask me for help.
