Ambleside's facility is terrible for the world-class tourist destination it is. It is a real off-putter to using what really is a very good service, doing the 1990s thing of hiding the buses round the back as if you're embarrassed about them. It needs a proper, impressive bus station, ideally staffed and with toilets and retail, opening in a more prominent location.
The Lake District *really* needs higher public transport use and fewer cars, so bad is the traffic. Stagecoach are doing their bit, but the National Park Authority really isn't.
