Te Ara Ahi — meaning “the pathway of fire” — is a cycling trail that links Rotorua with the geothermal landscape to its south, passing through four distinct geothermal areas over approximately 51 kilometres. Nicknamed Thermal by Bike, it is one of New Zealand’s official Nga Haerenga Great Rides and one of the most geologically dramatic cycle trails in the country. The route runs from Rotorua’s lakefront south through Whakarewarewa Forest, past the Waimangu Volcanic Valley and Waiotapu Scenic Reserve, to Waikite Valley Thermal Pools — riding through active geothermal terrain that would be unusual anywhere else in the world.

The Trail
The full Te Ara Ahi trail runs from Rotorua’s lakefront south through the Whakarewarewa Forest on a mix of purpose-built cycle paths, gravel track, and road connections. The first major section — Rotorua to Waimangu Volcanic Valley — covers 30 kilometres at Grade 2–3 and takes 3–4 hours. The second section — Waimangu to Waikite Valley Thermal Pools — is 18 kilometres at Grade 3 and takes 2–3 hours. Together they form the full 51km trail, which most riders complete over one to two days.
The Grade 2–3 rating reflects a mix of surface types and some undulation — it is not a technical trail, but it is not flat either. The trail passes through working plantation forest, native bush sections, and open thermal terrain, with the character changing considerably as it moves south and the geothermal landscape becomes more dominant.
The Geothermal Landscape
What makes Te Ara Ahi distinctive is the terrain it passes through. The trail crosses the edge of the Taupo Volcanic Zone — one of the world’s most active geothermal regions — and passes or provides access to four significant geothermal areas. Waimangu Volcanic Valley (the world’s youngest geothermal system, formed in the 1886 Tarawera eruption) and Waiotapu Scenic Reserve (home to the Lady Knox Geyser and Champagne Pool) are the two major stops, both accessible as side trips from the trail. Waikite Valley Thermal Pools at the southern end of the trail offer natural hot pools fed by a 96°C spring.
Riding It in Sections
The trail does not have to be ridden end to end in one go. Many riders choose to ride the first section (Rotorua to Waimangu, ~30km) and return by shuttle, visiting Waimangu as a destination. Others combine the trail with paid entry to Waimangu Volcanic Valley or Waiotapu as the centrepiece of the day. Shuttle services operating in Rotorua can arrange vehicle return from Waikite Valley for end-to-end riders.
