Lakeside & Haverthwaite Railway
A short, perfectly-formed steam line through the Leven valley that connects with the Windermere boats at Lakeside. Do train plus cruise and you have built the classic Lakes day without a single car park argument.
Lakes Aquarium
Newby Bridge, Cumbria
A small aquarium at Windermere's quiet southern tip whose party trick is the tunnel walk under the lake's own fish - otters, rays and piranhas fill out the cast.
It is an hour well spent rather than a destination, which is exactly right stacked against the steam railway next door and the boats outside. The combo tickets are the sensible buy.

Lakeland Motor Museum
Thousands of vehicles and period pieces packed into a riverside mill, with the Campbell Bluebird story told properly in its own gallery. One for kids who like machines; a surprisingly good wet-weather card.
Fell Foot
A National Trust lakeshore park at Windermere's quiet southern tip: grassy banks straight into the water, paddling, boat hire and an adventure playground. The easiest safe lake-swim spot for families.
