We love the sound of the Feather Down Field Spa, new this year. Nothing purpose-built in marble or chrome here. No well turned-out attendants or exotic fruit juices flown in from the four corners of the globe. Just DIY invigorating goodness in the middle of a field. Completely CO2 neutral, everything works without electricity or gas. For heating, only fire wood is used and it’s done by you. Don’t worry, you get an instruction pack! £87.50 (for a maximum of six persons) per part day (morning/afternoon or afternoon/evening). Available at Hollings Hill Farm Herefordshire and Boswarthan Farm Cornwall.
