Daytrip from London into a fairytale town - Cotswold

If you are in London, I would 100% recommend visiting the town of Cotswold from there. I found a tour through Viator, it was a traveller with around 16 people onboard, took us 1.5-2 hours trip from London, they covered 3 villages- Bibury, Bourton on Water and another one. And it was soo mesmerizing, the villages and towns are very pretty with rivers flowing through them, huge grasslands, horses and sheep grazing on those grasslands, cute little cafe and candy shops. Plus it was december, so all of the shops were doubly decked up with lots of christmasy decor. It was so peaceful to just to sit by the riverside eating a bagel or walking through the streets of the villages.
