Travel up Stuart St down into Kaikorai Valley and onto Taieri Rd. Continue the slog uphill almost to the top of Three Mile Hill Rd, turn right onto Flagstaff-Whare Flat Rd (big water tank on left) Cruise on the gravel up to the top of the hill to the “BuIl Pen” car park. From here the ride can be ridden clockwise or anticlockwise. Either direction requires some hill work. Head down Flagstaff-Whare Flat Rd until you reach an intersection, turn right onto Rollinsons Rd and travel up to a locked gate. Hop over the gate and then bike up a long gravel switchback to the top (Swampy Summit, 739m). Just past the doppler radar a 4WD track veers right, after about 100m a grassy undulating track veers hard right, travel along this all the way back to the Bull Pen. To ride anticlockwise, head up the 4WD track “Swamp Ridge Track” from the Bull Pen, following the route in reverse. (Do not ride up the Pineapple Walkway — this track is for walkers only)
