Special note about Holland:
I didn't find Holland all that great as a tourist, but I think it would
be a great place to live, for four main reasons:
Flat fields with lots of cows, and not a lot else. In the spring and early summer, Holland explodes in color as the tulips bloom, and in the winter the canals freeze over, which must be spectacularly beautiful. The rest of the year, you better like cows, or else you'll find the scenery pretty dull.
There are some nice museums in Amsterdam (I particularly liked the Reijks museum), and a few palaces and cathedrals you can visit. Other than that, I'm not aware of any outstanding monuments.
Beautiful in summer, freezing in winter, kinda rainy inbetween.
Holland ain't cheap. In particular, going out for a meal will cost a small fortune, unless you eat cheap sandwiches or something of that sort. There are campsites all over the country, though, so that's a great way to save money.
Eating in Holland was so expensive that I never really tried to find any "authentic" dutch food. You can find pretty much any kind of food in the big cities. I stayed with a Dutch family who ate fairly plain-but-tasty food: good breads, nice cheeses, sliced meats, fresh tomatoes and onions, cereals and toast for breakfast, that sort of thing.
The Dutch are wonderful people. Probably 99% of them speak English (they say everybody does, but I met at least two people who didn't, or at least said they didn't), and they're mostly very polite. I found them very helpful when asking directions and that sort of thing, even in big cities like Amsterdam. I think they probably get tired of being asked questions about drug legality (it's NOT legal, but "soft" drugs are TOLERATED), but they'll still answer politely. In general, I found them quite hospitable, and though I didn't find much "to do" in Holland, I'd gladly return.
Holland is a pretty clean place. 'Nuff said.
Flat. REALLY Flat.
Holland is an incredibly easy, pleasant place to cycle, but for cycle TOURING, I found it totally boring. Fields, more fields, and even more fields. Lots of cows. Lots of rivers. Not much else. Roads are good, and in the cities there are cycle paths EVERYWHERE, which is really nice. Outside the cities, I found the cycle paths (they go many, many miles between the cities) annoying, as they wound around like pretzels, and I often found it very difficult to make sure I was going in the right direction. I would almost prefer to ride on the roads, but given the trouble they've gone to to put in all those cycle paths, I imagine that's probably frowned upon.
