In Lake Tekapo township, turn off SH8 onto Lilybank Road (a gravel road) and travel to the end. Either park there, and cross the river on foot, or drive through the river (needs 4WD).
Spectacular glacial scenery, accessible via a relatively easy 4WD track through private farmland. However, the walk starts with a river crossing which is only possible at relatively low flows - so this walk is only for experienced trampers.
