Featured place: The Roundhouse, Pembrokeshire
There are few walks in Britain that can beat Pembrokeshire's coastal footpath. En route is the Roundhouse, a small eco-cottage overlooking St Brides Bay near Haverfordwest. It's a former croquet pavilion that has been turned into a model environmental building by a local architect...
There are solar panels and a wind generator (with a dial so you can read how much electricity they generate), a reed bed drainage system to ensure your waste water doesn't pollute the coastline, and a masonry stove that stores the heat in the walls overnight.
The small octagonal living area has a double sofa bed and there's just about enough room for an extra pull-out bed for two kids (so long as they don't mind sleeping like croquet mallets). In the bathroom, you can dunk in a steel-lined hot tub with a wonderful view over the bay, and the small "galley" kitchen has a Calor gas cooker and fridge. And if cabin fever sets in, there's home-made food and a bar at the Druidstone hotel a few hundred yards away. From the cottage, walk down to a wide sandy beach or take the higher route along the spectacular coastal footpath.
