Serpentine Scenic Reserve Road is a remote 4WD track in Otago that leads to the historic Serpentine gold mining site, including the Serpentine Union Church and old mining relics. Access is via Long Valley Ridge Road from Poolburn Dam, requiring a well-equipped 4WD. The final section near the church is impassable by vehicle, but you can park and walk the remaining 400m. Vehicle access is closed from the Tuesday after Queen’s Birthday Weekend until September 30 each year. The area is exposed and weather can change quickly, so come prepared.
