What is the weather like in the second half of October? Is there much rain?
I was there end of October last year. The days were sunny but we had one day of showers. Not as cold as you would expect in the mountains. Aristi is very beautiful, and you will not be disappointed!
I was there in early July - the weather was lovely at that time, but some could consider it a little warm.
It will be cold and can be rainy with storms and fog
The fall colors will be at the end but it can have sunny times as well
The water will be cold so I do not know about rafting at this time of the year
I've only been there in late November and there is a little rain.
I actually went in February when it was cold and snowy but my experience of Greece in the second half of October is that out of a weeks stay you may get one or 2days with a little rain and it can be chilly in the evening but generally I have always been lucky at this time and have been at least a dozen times when the weather has been good.
It may be worth contacting the hotel direct as there is a bit of a microclimate in this area
