Hi Sylvie,
There are 15 travellers booked on the 6th June and 21 travellers booked on the 13th June departure. The temperature will be around the 20 degree mark, with it dropping to around 15 degrees at night. Lake Como and the surrounding areas do often see quite a bit of rainfall in June - so make sure you pack a waterproof jacket.
Kindest regards,
Monty
