Uenuku Pines Mountain Bike Park sits in Waikune Forest on the edge of National Park village at Erua, Ruapehu, with a 3.6 rating from 5 Google reviews. Opened in late 2018 as the region's first mountain bike park, it offers around 20 short linked trails — roughly 15km of fast, flowing riding best suited to intermediate and advanced riders.
Forest bike parks are typically club country: volunteers cut short linked loops that riders lap repeatedly, and the fast bermed corners reward those who carry speed. Regulars check trail status before every visit, since forestry work and storm damage close sections at short notice, and match the grading honestly to their ability. Club membership usually funds the maintenance, so joining is part of the deal.
Riders must join the Ruapehu Mountain Bike Club, affiliated with Cycling New Zealand, to ride here, and the Mountains to Sea site carries current trail status — worth checking before you head for the pines at Waikune.
