Quito city in the clouds
Amazon jungle the Amazon jungle provides a fascinating contrast to the volcanos
Market in Saquisili an original market where animals and everything else imaginable is sold
Cotopaxi a good opportunity to breath some really thin air; the car might have a problem too
Train from Rio Bamba to Alausi riding on the roof through the country; great, if the machine doesn´t break down

Villa Rosa, Cuenca excellent cuisine and a good place to try ceviche
El Delirio, Riobamba charming restaurant in a historic house, you might also want to try the chocolate cake in the afternoon
Mare Nostrum, Quito

the decor is a mix between a monestary and the interior of a ship, accordingly they serve nice fish dishes

La Selva Jungle lodge one of the best (and most expensive) places in the jungle, but don´t expect much luxury; great food too
hotel Sierra Madre, Quito good location and charming rooms, especially the one with balcon on the top floor
hotel Ali Shungu, Otavalo nice hotel with a pleasant garden, helpful staff and a good restaurant
hosteria La Cienega, Lasso (near Cotopaxi) the guest rooms are not that convincing, but the atmosphere of the hotel is exceptional; horse riding facilities (if you are not accustomed to catch your horse, you might want to book a guide)

Galapagos you can only reach the Galapagos from Ecuador, they are expensive but worth every sucre (or dollar more likely)
Amazon jungle it is worth to go a bit further down, into the more remote areas, there are no leeches here (see Borneo)
buses it is very easy to get around by bus, you can also flag them down at any place
horse riding there are good opportunities to renew your horse riding abilities
train try to get on the roof (all the tourists will do the same, only the locals ride first class); it can be quite cold in the morning and get very hot in the afternoon (when the train breaks down)
