There is a road just outside, and some outbuildings. Arrive by car across the pasture, park rather far away, walk a narrow path all the way across, with the views, wildflowers, smells, sounds, and you are there. Feeling very Heidi-ish.
Goats everywhere. This one will follow if you go Mnahhh mnnnnaahhh.
Goats everywhere, Heidi House, Maienfeld, Switzerland
Also chickens. And some ducks.
Grandfather's and Heidi's House, Maienfeld, Switzerland (same goat - still following)
Grandfather's little house up the slope, is a good way up a mountainside, but not hard to walk, we heard. We were in the car. Walks are nice, but then walks require the walk back, and there goes the whole afternoon.
But road signs for cars are not helpful.
Most people seem to come by train, and take a taxi or a long walk up the mountain to the Heidi House, as it is called. By car, simply give up on the map, go to the railway station, and pretend you are walking. Follow those signs.
Museum,Grandfather's house, kitchen, Maienfeld, Switzerland
Shed, and 1930's caretakers' cottage beyond, Heidi House, Maienfeld, Switzerland
There is a sizable residence built in the 1930's and we understand it is for the caretakers - tending the animals, overseeing the museum and shop, and all that go with being famous. Just turn your head away and pretend it is not there.
Johanna Spyri, the author of Heidi, remains largely a mystery. She died a widow, but ordered that all her correspondence be destroyed at her death. See http://www.swissinfo.ch/eng/archive.html?siteSect=883&sid=742902&ty=st/. She had children, they died, as did her husband, and none of her other works attained the popularity of Heidi. She is buried in Zurich. See ://www.online-literature.com/spyri/
