I thought Monserrate was the fairest mountain of them all until JB drove us to Lake Guatavita. The 1.5 hour drive up was stunning (I'm running out of adjectives of praise). It was so gorgeous that I actually fought my fake narcolepsy and stayed awake for the ride, which is a first for me. The story of this lake is like an episode of Xena: Warrior Princess, complete with animal gods, infidelity, and hidden treasure.
Love these guys!
