I live at the top of Crouch Hill (Mount View Road) and find Shepherds Hill from Park Road to Highgate is a good one to include as well as North End Road from Golders Green station up to the roundabout at what used to be Jack Straw's Castle; alternatively, the scenic route with less traffic is via Hampstead Garden Suburb up through Turners Wood.

Hope to do more hills now that snow/ice has gone!
