Wales is a gem of a country, offering old-world charm and 21st century adventure. Starting off in Cardiff, Colleen Kelly explores the capital's history at the famous Cardiff Castle, and then she takes a leap in time at the wildly popular Dr. Who exhibit, which brings the locally-produced TV show to life for visitors. Colleen then travels up the coast to Swansea to learn about Welsh technology, before heading to Llanelli to learn how to play rugby from one of the country's greatest all time players, Phil Bennett. Colleen tours Portmeirion, a beautiful getaway tucked along the coast, where young and old come to unwind and indulge in the breathtaking views. Not far from Portmeirion, Colleen takes a ride on the Ffestiniog railway, which is in the Guinness Book of World Records as the oldest narrow gauge railway in the world! Last stop is Conwy in Snowdonia, home to the smallest house in the UK and the train station with the longest name, Llanfairpwllgwyngyllgogerychwyrndrobwyll-llantysiliogogogoch. While in the Snowdonia region, Colleen takes a cooking class with local children and indulges in Welsh specialties at the Bodnant Food Centre. To top off her visit to Wales, Colleen gets her adrenaline pumping on the fastest zip line in the world...going over 100 miles per hour!
