After breakfast, there are two options for the day:
Option 1: Tiwanaku & Lake Titicaca (10-12hrs departs at 7:30am) Take a van to the UNESCO site Tiwanaku, a pre-columbian settlement, for a private tour and time for exploration of the site and museums on your own. Then, off to visit many sites along the shores of Lake Titicaca before heading back to La Paz.
Option 2: Bike the North Yungas Road (8-10hrs departs at 6:30am) Take a shuttle bus to La Cumbre (15,250 feet) and ride mountain bike, often out of the clouds, through the beautiful valley past waterfalls, snow-capped mountains and cloud forests to the dense jungle in the valley. Snacks and informational stops along the way with your guides. All equipment (including helmets, gloves, knee & elbow pads, wind/rain pants & jacket) provided as are the full-suspension Kona bikes with hydraulic brakes. Enjoy a large buffet lunch, a pool and showers before heading back to La Paz by private bus.
Tiwanaku was once the capital of the pre-columbian Tiwanaku culture. It is one of the largest archaeological sites in South America (~4 km2). It dates back to around 800AD and had an estimated population of about twenty thousand people.
N. Yungas Road was built in 1930 by carving into the rock faces of the mountain which created sheer drops of 1,000+ feet off the shelf. It goes from 14,783 ft / 4,506 m to 5,003 ft / 1,525 m and is one of the longest continuous stretches of downhill road in the world. Some sections are only about 11 ft /3 m wide, unpaved with no guardrails. Combine that with the often heavy rain and thick fog common to the area, and you can see how the road got its nickname: The World’s Most Dangerous Road. However, since a new road was built in 2007, the traffic has been greatly reduced and with it, the danger.
