La Paz...

...highest capital city in the world, yet the smallest museums ever. Easy to do 5 in an hour, although set aside a whole 30 mins for El Museo de Coca.

Bolivia...

...the size of France and Spain put together, yet the country´s top crag is rubbish (http://www.geocities.com/msivila/Aranjuez.html). Mostly chossy conglomerate rubble, though a decent pinaccle gave a good FR5 solo.

You can combine a trip to the crag (14 km south of La Paz centre) with a visit to the Val de Luna, a maze of mud spires much like a monochrome grey Bryce Canyon. Makes for a pleasant afternoon´s escape from the mad bustle of the city.
