The Waihaha trail is 30km, about 4 hours, of mellow flowing singletrack bliss. It weaves its way through forest with stunning river, canyon, lake and mountain views. It's never very steep but it is undulating! It's an exceptionally well made trail in an amazing landscape. Riding it is a wonderful mini-adventure that normally includes a road shuttle, a boat shuttle, lunch along the way, a swim in the lake and, on a clear day, photos for a lifetime.
There are toilets at the start, midway and end of the trail. You'll get cellphone reception here and there.
