I live on the edge of the Peak District, so 10 miles gets you to some pretty wild-feeling places.
The Goyt Valley for shelter and trees (for hammocking).
Three Shire Heads for a bivvi
A few open moors to choose from
The Roaches
Lud’s Church near Gradbach
I reckon 50% of my bivvies have been within 10-15miles. Especially with my eldest son. Younger son will be getting all the gear for his 10th birthday this April, so I’ll probably be revisiting them all again this year!
Staying close lets you choose a good weather forecast and makes it easy to get back at a reasonable time in the morning for work if needed.
