Here's the solution I came up with--- steps cut into the hill and framed with treated wood. It's a typical technique when building a mountain trail; heavy work but with Jehan's help we banged it out in a day.
Jehan is here from France, working as a WWOOFer. Under this program,Worldwide Opportunities on Organic Farms, kids volunteer to work at organic farms throughout Europe for their room and board. It's a great way to see the world on a limited budget and learn organic gardening/farming techniques. Jehan has been in Scotland since May, on the Isle of Skye,Perthshire, and now at Cottarton.
