Bike ride to Coroico
Not for the faint-hearted, the old highway from La Paz to Corioco is a very narrow road that is now for the exclusive use of mountain bikers. It snakes through the Yungas hills and must be approached with caution. Known as the World's Most Dangerous Road due to the fatalities when trucks were allowed on the road, you are rewarded with spectacular views throughout the ride. You can take a bus back to La Paz that afternoon, or enjoy the charms of lower altitude Coroico for a day or two.
