Te Toto Gorge carves a vast gouge in the flank of Mount Karioi down towards the Tasman Sea. A hiking trail leads up the side of the gorge, through dense native bush to a lookout, and on to the summit of the mountain. On a clear day there are stunning views over the local coastline, and you can see as far as the perfect cone of Mount Taranaki.
The trail is steep, narrow and challenging, especially if slicked by recent rain, and chains and ladders have been fixed to help negotiate rocky crags along the ridge. After a large outcrop the track winds north for a way, then climbs steeply back to the ridge. A short side track takes you to the lookout point.
From the junction it takes a further hour on the ridge to reach the peak, around 3 hours in total (one way).
The car park for Te Toto Gorge is on Whaanga Rd, approximately 15 minutes drive beyond Whale Bay, 13km from Raglan. A viewing platform for the lower gorge is just beyond the car park.
