The second day of our mountain biking excursion was based around the Chimborazo Volcano. We did a bit of hiking before we set off on our bike adventure this day, up to the Whymper Hut base camp (used by mountaineers sleeping before the summit push), and were pleasantly surprised to find that although we climbed to just under 16,400 ft, we were appropriately acclimated and experienced no altitude sickness.
It was fantastic to see wild Vicuña (small llama/alpaca type animals) all around us as we descended by bike. I even took a short video in hopes of capturing the natural beauty all around us. It was basically like being in a NOVA special :)
