Taking the loop clockwise, cross the bridge and follow the marked route across Greenstone Station's open paddocks for an hour to Elfin Bay.
An initially steep climb through red beech eases before reaching picturesque Lake Rere (running water). This was a popular tourist destination in the late 19th century.
Pockets of mountain beech and grassland lead you to a second bridge and a brief climb to join the Greenstone Track. To finish this loop continue on Greenstone Track back to the start of the Lake Rere Walk.
Park at the Greenstone carpark which is 1 hour from Glenorchy.
Beware of unbridged stream crossings in heavy rain.
