Hello! I may have the opportunity to spend about a week in the UK next summer with my 12-year-old daughter. I have been to England several times, and each time my husband has been comfortable with driving there, but he won't be there for this trip & I am not brave enough to drive in the UK, so I am trying to find a city to use as a home base that is easy to get to from a major airport and offers both a good amount of sightseeing and/or easy connections to other cities on public transportation for fun day trips.
I am interested in sporty things like hill walking, possibly surfing (don't people do that in Cornwall?), as well as history - as well as anything random that might appeal to a 12-year-old (helping on a farm, kayaking, etc.) I've been to London 2x already, so I don't really want to base out of there. We've spent about a week in the Cotswolds, but nothing north of there or south of London.
I would also love suggestions in Scotland if anyone has them. Thanks so much.
