Northmavine is part of the Mainland, but only just! Just beyond Brae is Mavis Grind, where a narrow isthmus joins Northmavine to the rest of Mainland. The narrow neck of land that separates the North Sea from the Atlantic here is just 90 yards (80m) wide and you could indulge in one of the shortest coast to coast walks anywhere. An interpretive geology wall built by Geopark Shetland describes the spectacularly diverse geology of the area and a panel tells of some of the history of the area.
Travelling north on the A970 through amazing road cuttings that contrast grey gabbro rock with bright red granite there are wonderful views over Mangaster Voe. Generally all along the route the glacially moulded landscape meeting the fierce Atlantic coastline makes for scenic cycling. If you are in no hurry on this short route, we recommend a 2 mile (3.5km) diversion along the single-track side-road to Gunnister and Nibon; a beautiful ride on a rollercoaster road with wonderful views of Gunnister Voe and the Isle of Nibon.
