Prepare for a memorable ride. This section takes you up to the summit past the Peter Verigan memorial and on to Bulldog Tunnel, the longest on the CPR (1 km – be sure to bring lighting!) The route from Paulson to Castlegar station is about five hours, and has beautiful vistas of the Arrow Lake and the remains of old towns which dotted this valley. There is a huge Natural Arch rock formation a short ways from the rail grade, and a creek which issues out of a cave. Ask for directions as there are no signs at present.
Follow Highway #3 north out of Christina Lake towards Castlegar. 100 m before the Paulson Bridge take the Paulson Detour Rd. up then down into the valley. This leads to the access point for the Trans Canada Trail.
