In Chile,
Arica in the Atacama Desert is superb, try the Hotel Arica, but eat at the Seafood Restaurant with the palapa roof 500m east of the hotel.
Puerto Montt half way down the country is curiously bavarian in appearance, but with snow capped volcanoes nearby, as well as being just down the road from Vin~a del Mar where most of Chile's wine is produced- GREAT tours!
Punta Arenas down at the bottom is better suited to low winged aircraft, as really high winds can flip Cessna-types. Close to los glacieres and torre del paines national parks. Quick hop to Teniente March base in Antarctica if you're in an otter, if not DAP could take you in theirs.
In Ecuador, the taxi ride to the Hotel Oro Y Verde will forever cure you of EVER being scared in a car again!
