Total duration (RT): 4h (small loop) / 6h (big loop)
Total distance (RT): 9km (small loop) / 11.3km (big loop)
Positive elevation: 500m (small loop) / 700m (big loop)
Very well marked ridge and forest trails.
Some very steep sections (bottom trail in the forest and final climb to the pluviometer).
Vertignous but secure ridge trail after the pluviometer.
It is recommended to wear pants to avoid abrasions from Anuhe ferns.
Going deeper into the Tipaerui valley, take the left road going up to the private housing estate of Mamaia, following the signs "Pic Vert".
When you get to the subdivision gate, you can park at the water tank if you want to follow the big loop.
Otherwise, to access the start of the small loop, you can wait for a car to enter or exit the housing estate
to cross the gate and go up to find the other water tank on the heights of the subdivision.
Make sure not to disturb the residents of the subdivision.
To the left of the water tank, you will see a small path.
After a few meters in fairly dense vegetation, cross the dry bed of a stream.
An ascent of around 30min begins here to Mount Papaihona, which already offers a magnificent view over Moorea.
Some portions of the trail are very steep and can be slippery, good shoes strongly recommended.
From there, walk along the ridge and admire an even more beautiful view of the various valleys and of Moorea. This part is a mountain bike trail made up of many jumps, and a large wooden jumping deck on the heights. When you reach this large deck, a bifurcation awaits you a few meters further. To go up to the pluviometer, turn left. Otherwise, turn right and go down to the subdivision on the other side, in the pine forest.
The ascent to the pluviometer takes about an hour from this junction. You first pass in front of a hunter's shelter on your left. Continue then pass under a vegetal arch, before plunging again into the forest. Follow the path, which is sometimes blocked, but still clearly visible. You reach the pluviometer after a last very steep ascent of around thirty meters elevation.
After the pluviometer, the trail continues on the ridge in the middle of the Anuhe ferns, wear pants to avoid abrasions. The path is sometimes vertiginous, but relatively well marked and without risk. After about 30min on the ridge, you arrive at the Green Peak (or Toanui summit) which culminates at 1167m. Splendid point of view on the mount Aorai which overhangs the waterfall of Loti, the diadem in front of you, and Mount Marau, and of course Moorea behind your back. Beautiful !
Follow the same path for the descent, until the junction of the jumping deck. Turn left and go down to the housing estate water tank through the pine forest. You will find some pretty viewpoints over the Tipaerui valley and the lagoon.
Return to the subdivision gate by going down the road. If the gate is closed, you can go around it on the left, being careful. The circle is complete!
The small loop follows the same route as the big loop from the top of the subdivision. Only the lower parts of the big loop (ascent on the Papaihona ridge and descent into the subdivision) are missing. You can either start with by the track in the forest to the right of the housing estate water tank (chain with "no entry" sign) or cross the subdivision to directly access the ridge.
