There is a choice of two exits from Walls to join the A971 to Bixter; either take the A971 direct to Bridge of Walls, or take the minor road north to join the branch of the A971 near the Neothlitic homestead and field system at the Scord of Brouster which is well worth a visit.
At Bixter there is a shop and toilets. From Bixter the route on the B9071 climbs again to give views to the west over Clousta and Aith Voe and the unspoilt wild moorland and hills to the east. The road becomes single-track beyond the settlement of Aith. About 1.5 miles (2.5km) further on the road crosses the Burn of Lunket where a singposted path follows the burn to the waterfall and is a gateway to some exhilarating hill-walking across the wonderful views beyond.
The climb from the Burn of Lunklet over West Hill of Burrafirth is a little bigger than those already passed and then the final climb from Gonfirth over Fielnadringa is bigger still. At 439 feet (134m) this is the highest point on the Cycle Shetland touring network. This long climb is compnsated for by some of the best wild upland scenery in Shetland.
