Don is a great host and the location is equally great We've stayed with Don for a few days to do the Tongarino crossing, Waiotapu, and the Wairakei terraces.
Don was a great host throughout, while his house is in a very nice location on top of a hill with some great views of the surroundings.
If you are looking for a great place to explore the volcanic sites and Tongarino with a great host, look no further!
