Seminar participants arriving in Tucson can call the Avalon Gardens' main office to arrange complimentary shuttle service from the airport to the seminar. The EcoVillage is located in a rural area but shopping and a small market are close by. Please contact our office with any questions or special requests as we can accommodate most needs.

Avalon Gardens is one of the world's largest and longest sustaining EcoVillages, situated on 220-acres of historic & sacred agricultural in Southern Arizona's fertile Santa Cruz River Valley. We are a fully operational micro-society showcasing the success we have had incorporating a modern lifestyle within the sustainable context of a land-based society.
