Mountain Biking
Tywyn is an ideal base for a mountain biking holiday, with a number of trails in the area. The ascent of Cadair Idris from Llanfihangel y Pennant is classified as a bridleway, and therefore can be used by mountain bikes. It's a tough slog up (you'll be carrying in places), but the descent (from 892 m at the summit to only a few metres above sea level in the valley) must rank as one of the finest in the country. Bear in mind that the right of way does not follow the farmer's gravel track for the whole length - be sure to look out for signs and/or use a map in order to stick to the legal route. Not recommended for summer weekends due to the number of hikers. There are other ancient roads in the area which can be used by mountain bikes. The pass of Nant Braich y Rhiw from Rhyd-yr-onnen, south of the village of Bryncrug, through the Tarren hills to Happy Valley is a popular route, though it can be very muddy after rain as it also used by 4x4 vehicles. The Ffordd Ddu (Black Road) leads from the village of Llanegryn, across the western flanks of Cadair Idris and down to Dolgellau via the Cregennan Lakes. Ordnance Survey Explorer Map sheet OL23 Cadair Idris and Bala Lake is essential to follow these routes. There are a number of marked trails in the Dyfi Valley, centred around Machynlleth, 15 miles to the south-east, including the purpose-built CliMachx route. Coed y Brenin, near Dolgellau, 20 miles to the north, has 6 waymarked trails.
