Summer has arrived, and the landscape is in full bloom - it is the perfect time to get out and enjoy the countryside. And in a special programme, Countryfile are cooling down by the water's edge in celebration of the Great British summer. Matt travels along the coastline of south Wales with Sam Evans and Shauna Guinn, known as the first ladies of barbeque, sourcing the best cuts of meat for their summer beach party. Meanwhile, Naomi Wilkinson enjoys a summer evening punt along the River Cam in Cambridge, where she is joined by Iain Webb from the Wildlife Trust on the lookout for a feeding frenzy of bats. John Craven is on the river Waveney in Suffolk bringing in the summertime bulrush harvest for the first time in more than 50 years. Sean Fletcher gets on his bike and heads off the beaten track along the beautiful Pembrokeshire coastline to enjoy a spot of wild camping. And Adam is in Northern Ireland, where summer for one farmer means taking to the water with his cattle.
