With two huts you have the choice of what to stay in. The new or the old. Steady and easy enough track to location with some boulder hopping to make your way there along a river that can get high. The trail to here is partly on an old timberline trail. Maybe bring your bathing suit also as hot pools are near however I did not see them myself. From here different huts to head off to, all in the true backcountry deer stalker areas.

The tracks that lead to these huts (if there are any) range from easy to extremely difficult. Some may be a day walk in, others for an overnight stay, while others will take multiple days. Back country skills may not always be needed but the majority will need some knowledge to take on the adventure. Huts can be busy places but some of the more isolated huts can be seldom visited. Because of this they can be on the DOC chopping block due to lack of funds. I am hoping that a series of geocaches at huts around the country may just encourage others to go to where few set foot.
To plan for your trips into the backcountry you can find a lot of information here. Always be prepared with the right equipment and food.
