Coed y Brenin (Welsh for King's Forest) is a forest in the Snowdonia National Park, North Wales near Dolgellau at grid reference SH7127. It is popular for its mountain bike trails and hiking paths. It has several man-made mountain bike singletrack courses in a woodland setting, varying in length from 12 to 38 km (7 to 23 mi), and one dual slalom course. The site is owned and operated by Natural Resources Wales, and covers an area of some 9,000 acres (36 km2) around the valleys of the rivers Mawddach, Eden, Gain and Wen. There is no charge for using the trails, but there is a charge for the car park at Coed y Brenin Visitor Centre. This costs £2 for first 2hours and then 40p per 20minutes capped at maximum £7. All of the proceeds go towards the maintenance and improvement of the forest trails. Coed y Brenin was identified as a potential mountain bike race course in 1990, and the first races were held there in 1991. The initial course had to be chopped out of an impassable rock-strewn terrain. Shortly afterwards a Mountain Biking hire shop, together with a visitor centre and café were opened at Maesgwm. Five waymarked trails were developed by Dafydd Davis who was employed by Forest Enterprise as a Forest Sports Development Adviser, grew Coed y Brenin into a major UK mountain biking centre. Davis received an MBE in the 2004 Queen's Birthday Honours list for 'services to forestry' relating to his work on this resort. A new £1.6 million visitor centre opened in the summer of 2006. Since the opening of the centre, the trail offering has grown to eight mountain biking trails, eight walking trails and five running trails. These trails are way marked. The visitor information desk is available seven days per week, throughout the year (except Christmas Day, Boxing Day and New Year's Day) during the gift shop opening hours of 10:00hrs and 16:00hrs. There are a number of picnic tables around the main car parks within Coed y Brenin Forest Park plus many more on the waymarked walking trails. Some of the picnic tables have metal frames for holding disposable barbeques. There are also stone BBQ plinths in Glasdir and Ty'n y Groes picnic sites.

Gwynedd (/ˈɡwɪnɛð/; Welsh: [ˈɡuɨ̯nɛð]) is a county in the north-west of Wales. It borders Anglesey across the Menai Strait to the north, Conwy, Denbighshire, and Powys to the east, Ceredigion over the Dyfi estuary to the south, and the Irish Sea to the west. The city of Bangor is the largest settlement, and the administrative centre is Caernarfon. The preserved county of Gwynedd, which is used for ceremonial purposes, includes the Isle of Anglesey. Gwynedd is the second largest county in Wales but sparsely populated, with an area of 979 square miles (2,540 km2) and a population of 117,400. After Bangor (18,322), the largest settlements are Caernarfon (9,852), Bethesda (4,735), and Pwllheli (4,076). The county has the highest percentage of Welsh speakers in Wales, at 64.4%, and is considered a heartland of the language.The geography of Gwynedd is mountainous, with a long coastline to the west. Much of the county is covered by Snowdonia National Park (Eryri), which contains Wales's highest mountain, Snowdon (Yr Wyddfa; 3,560 feet, 1,090 m). To the west, the Llŷn Peninsula is flatter and renowned for its scenic coastline, part of which is protected by the Llŷn AONB. Gwynedd also contains several of Wales's largest lakes and reservoirs, including the largest, Bala Lake (Llyn Tegid). The area which is now the county has played a prominent part in the history of Wales. It formed part of the core of the Kingdom of Gwynedd and the native Principality of Wales, which under the House of Aberffraw remained independent from the Kingdom of England until Edward I's conquest between 1277 and 1283. Edward built the castles at Caernarfon and Harlech, which form part of the Castles and Town Walls of King Edward in Gwynedd World Heritage Site. During the Industrial Revolution the slate industry rapidly developed; in the late nineteenth century the neighbouring Penrhyn and Dinorwic quarries were the largest in the world, and the Slate Landscape of Northwest Wales is now a World Heritage Site. Gwynedd covers the majority of the historic counties of Caernarfonshire and Merionethshire.
