The downside of camping in Autumn is that you have limited daylight hours.
We had a choice – first morning sun, or last afternoon sun – for our tent site. We opted for last afternoon sun. Which meant the inside of our tent was still cold (and the outside still damp), until the sun arrived around 11:30am. However, we also kept the sunshine until after 4pm. Other than one foggy morning and one breezy evening, we had still, calm, clear weather for 4 straight days.
