Went up to Cambridge for the day with my wife last Sunday. A decent day trip from London. We caught the train from Kings Cross railway station (£16 return per person) in the morning. On arriving, we walked to Trumpington Road from where we caught the open-top City Sightseeing bus (£14 per person). We hopped off the bus in the town centre and started browsing the shops and the outdoor market. We picked up some nice goodies from the market like fresh jam and rhubarb! As for the town, we highly recommend the chocolates from Chocolat Chocolat and the cakes from Fitzbillies. Following the shop browsing and lunch, we headed to Parker's Piece: an awesome green common area to chill out. Lastly, we walked down Mill Road to the Abu Bakr Masjid where we caught the Asr (afternoon) prayer. And then onwards to the railway station where we caught our return train. All in all, a good day out from London and some fresher, cleaner air!
