On their custom tour of Peru, Ecuador & the Galapagos:

"We had an amazing time. Everywhere we went was a new surprise!! We even managed to hike up to the Inca Gate at Lake Titikaka (with a few breathing stops!). The Galapagos were quite different from expectations, they are new (-ish) volcanic rock and have virtually no growth apart from a few scrub trees. The birds are not in the least afraid, and just watched us walk by. Everything went well."
