Ride the rails on quirky, converted former golf carts along the railway line linking Taumarunui to the tiny hamlet of Whangamomona in the Taranaki region. The most spectacular trip takes in 20 tunnels. Other options include a rail and jetboat combo and a longer two-day excursion covering the full 140km from Taumarunui to Stratford (including an overnight stay in Whangamomona).
