Our off grid place is on an outer island in the northernmost islands of Tonga. Fresh air, clean water clear to 100 meters, dirt you can smell the nutrients in, friendly people, whales and dolphins for swimming. Our "pool" is a beautiful turquoise lagoon off our sandy beach we use for doing aquacranial therapy in the ocean. Lots of fruit trees and garden. We have 4 acres, about a 30 minute boat ride from the main island in the Vavau group.
We also live part time on Maui. On parts of Maui you can live off the grid but in most places not possible. Our place is in Wailea to be close to the ocean. Really hard to get fresh produce or garden. Drought, poisen air, poisen water. Hawaii has the highest rate of extinction of both plants and animals in the world. Love those whales and dolphins though. Plan to spend more time in Tonga each year. 5 years now.
Nice introduce yourself post you started by the way. Cheers
