We have just returned from Quito which we visited prior to a Galapagos cruise.
Having read previous recommendations we decided to hire Lincoln Guaman (firstname.lastname@example.org) for 3 days. He suggested the itineraries. We had an excellent time with him trekking in the cloud forest, visits to the top of volcanoes, and to local markets.
He is exceptionally pleasant to deal with, speaks excellent english and is very knowledgeable.
The drivers in Ecuador seem quite mad but we always felt confident with him because of his safe driving. It was a lot cheaper to hire him than to go on organised tours and we had personal service.
