Starting from the Tekapo Hot Springs, follow the signs for the Mt John Summit Circuit Track which will lead you into a mixed forest. The ascent through the forest is gradual though steep.
You will exit the forest after 45 minutes and find yourself in an open tussock grassland field. From this point, the track still continues uphill. Along the way, you will come across a gate which you will have to open and close.
At the top of the hill, you will reach a junction: continue right to follow the track for South Summit. The left side of the track leads to the Astro Café.
The South Summit track allows you to walk around the summit of Mount John in order to truly experience 360 degree views of the Mackenzie basin, the stunning Lake Tekapo and the snow-capped mountains in the distance.
On the South Summit track, you will find a bench where you can sit and take in the views. You will also find an information panel naming the surrounding mountains.
The forest can be cold in the autumn and winter and the grassland is completely exposed to the elements, so it is best to come equipped for any weather.
