VFR in Holland
It is of course possible to fly VFR in Holland. However, they do require you to have a transponder.
Having said that - I flew through Holland recently in my 1936 Miles Falcon - transponder bust on the way down to Dover (law of sod) - Dutch were fine about it.
You will be talking a lot of the time to Dutch Mil for a Flight Information Service. Very helpful indeed. THe Dutch like us Brits it seems!
I recommend Midden Zeeland - great Restaurant on the airfield and nice long/ wide grass runway - very good waterside hotel in sight of the airfield (cheeeep!) - 10 minute walk or blag a lift.
Hilversum is also really nice.
In Germany, a cracking place to visit is St Michelisdon. Superb restaurant on the airfield - served by a delightful late 30's (phoooor!) lady with bumps in all the right places.
So - relaxing, scenic flying in Holland - you will lose quickly count of the windmills - and low - level is pretty normal there too - you will likely be cleared 'not above 1500ft'. No mountains to worry about in Holland.
If you go into town (Utrecht) from Hilversum, there are bicycles everywhere - all lunatics on them - you need eyes in the back of your head. Funny to fly all that way and get knocked down by a cloggie on a pedal bike!
