These falls are perfect for a pit stop on your road trip. Just a 1 minute walk from the road or 20m off SH2 at Karangahaki.
The trail will take you to the bottom of the falls and greet you with a larger pool which is perfect for swimming. There is only a small area of land around the waterfall and can get popular over summer.
Near by is a cycle track and/or walk that will take you parallel to the gorge, through ruins and over the famous bridge and into the tunnel( Hauraki Rail Trail Tunnel, 1km long). Also near here is the old Karangahaki gold mines which you can explore, take a torch.
