I'm fairly regular there. If you want a scenic route from Biggin I'd recommend that you do one of the following:-
- Drop down to the South coast at earliest possible, follow the coast.
- M25 Corridor to about Lasham, X-country to route abeam Popham, then Chilbolton, follow the Test Valley south to Romsey, ded-reckon to Beauleau, either follow the Beaulieu river south to the coast, or ded-reckon south-west-ish to Lymington, cross to the Needles overhead Hurst Castle, follow the coast around the south of the Island, Bembridge is very visible not long after you've passed abeam Sandown.
Propeller Inn on the edge of the airfield is very good, but I flew in January and it was closed for redecorating, the PPR number for Bembridge will be able to tell you if they're open or not since it's Britten-Norman's preferred local.
Also if you are going to need fuel, check it'll be available (again on the PPR No.); it isn't always at weekends.
