Rolling hills without any steep climbs are the order of the day for this HITR route.
The Henry VIII Gravel Loop
The Henry VIII gravel loop extends the Chartwell loop. Rather than heading over to Chartwell and Toys Hill, it heads further south to Hever Castle (home of the Boleyns hence the route name), Chiddingstone castle & village before a steep climb up Yorks Hill and the return leg to Surrey.
