Originally a motte and bailey Norman castle, only the earthwork mound and ramparts remain now. The castle is accessible by public footpaths from the nearby village of New Radnor and the castle still command a ranging view over the village and countryside. The castle's former use as a gaol ensured New Radnor's status as the former County Town before that status was moved to the larger Presteigne.

This is the start point of the GlyndΕ΅r's Way National Trail which winds through mid-Wales and ends at Welshpool. It's not as popular a trail as Offa's Dyke which is the main reason you'll meet other hikers here in Knighton.

Elan Valley is a mountain bikers dream. A mix of natural trails that follow the reservoirs and crest the lofty tops of each valley. There's also a great trailhead in the middle of the valley at Nantgwyllt for some great flowing singletrack.

Public transport options directly to Glascwm village for cycling access are limited. Many cyclists prefer to drive to starting points like New Radnor or Builth Road, which are common departure points for the longer routes. For the Elan Valley, there are some public transport links, but planning ahead is essential.
Generally, you do not need a specific permit to cycle on public byways and bridleways in the Glascwm area or the Elan Valley. However, always respect private land and adhere to any local signage. For specific information regarding the Elan Valley, it's advisable to check the official Elan Valley Trust website.
Glascwm itself is a small, tranquil village with limited amenities. For cafes, pubs, and accommodation, you might need to venture to nearby towns such as Builth Wells or Llandrindod Wells. Planning your route to pass through or near these larger settlements will provide more options for refreshments and breaks.
Given the varied terrain and potential for changeable weather in the Radnorshire hills, it's best to dress in layers. Waterproof and windproof outer layers are highly recommended, even in summer. Sturdy cycling shoes, gloves, and a helmet are essential. Always carry enough water and snacks, as services can be sparse on remote sections.
While the focus is on natural landscapes, the region does have historical context. Some routes might pass by ancient drovers' tracks or offer views towards sites like the historic St David's Church in Glascwm. The Carneddau Hills (Brecon Beacons), though further afield, are also a historical site.
