Region: Abergavenny and the Black Mountains, Bannau Brycheiniog (Brecon Beacons), Monmouthshire, Wales
The Abergavenny Three Peaks Challenge is a huge 21-mile circular walk linking the three mountains surrounding the town: Blorenge, Sugar Loaf and Skirrid Fawr. My route starts beside Bailey Park, climbs directly up the middle of the Blorenge, crosses to Sugar Loaf and finishes by approaching the Skirrid from the back before returning to Abergavenny.
With approximately 4,672 feet (1,424 metres) of ascent, difficult navigation, long stretches of hard surface and three demanding mountain climbs, this is not an ordinary day walk. I completed it in about 8½ hours including stops, but many walkers should allow longer depending on fitness, conditions and navigation.
Looking for the organised event? Many people use “Abergavenny Three Peaks” when searching for the annual South Wales Three Peaks Trial. This page covers my independent three-mountain route. For the four official challenge options, preparation and my experience of completing Gold and Platinum, read my South Wales Three Peaks Trial guide.
This route is best attempted with company. It is a long, tiring day and walking with someone gives you support if an injury, navigation problem or emergency occurs. Both walkers should still carry suitable equipment and know how to use the map or GPX.
Parking, start point, GPX and navigation
- Start and finish: Fairfield car park beside Bailey Park, Abergavenny.
- Google Maps: Fairfield car park.
- Route type: Circular and completed entirely on foot.
- Outdooractive route: View and follow my Abergavenny Three Peaks route.
- GPX: Download the Abergavenny Three Peaks GPX file.
- Navigation warning: This is difficult to navigate without a map or GPX. Do not rely only on a written description, phone signal or seeing the next mountain.
- If you are unfamiliar with GPX files, read my plain-English guide to what a GPX file is and how walkers use one.
Before leaving: check the weather, daylight, path access and parking information. Download the route for offline use, charge your phone and carry a power bank or separate navigation device. A GPX is an aid rather than a replacement for judgment and mountain awareness.

How difficult is the Abergavenny Three Peaks Challenge?
This is a strenuous endurance walk. The mileage is significant, but the defining difficulty is combining three hard climbs with long connecting sections. Some of those links are on concrete or other firm surfaces, which can become punishing on tired feet even though they appear easier than mountain ground.
The direct ascent of the Blorenge is brutally steep and may be extremely muddy in winter. Sugar Loaf requires a much longer, sweeping climb, while the rear approach to the Skirrid delivers a short, sharp final test after many hours of walking. None of the individual sections is technically extreme, but the accumulated distance, climbing and fatigue make the whole route difficult.
Stage 1: Abergavenny to the Blorenge
Start at Fairfield beside Bailey Park and make your way through Abergavenny towards Llanfoist. The Blorenge dominates the view ahead and gives you an immediate sense of the scale of the day.
The lower approach enters woodland where leaves, water and repeated footfall can create deep mud. Stiles and uneven paths slow progress before the trees eventually open onto the mountain. From here, the route heads directly up the middle of the Blorenge. It is exceptionally steep and may require careful hand and foot placement, especially when wet.
Do not attack this first climb as though it is the whole walk. The summit is only mountain one, and using too much energy here will be felt during the long approach to Sugar Loaf.
Stage 2: Blorenge to Sugar Loaf
After crossing the Blorenge, descend towards Govilon and begin the lengthy transition to Sugar Loaf. This part of the route includes canal, lane and road walking. It gives the climbing muscles some relief, but the hard surface creates a different kind of fatigue.
The route eventually leaves the easier ground and begins the sustained climb towards Sugar Loaf. Unlike the direct Blorenge assault, this is a long, sweeping effort. Settle into a manageable pace, eat and drink before you need to, and remember that the Skirrid is still waiting beyond the second summit.
Stage 3: Sugar Loaf to the Skirrid
Leave Sugar Loaf and begin another long connection through lanes and farmland. This section can feel mentally difficult because the final mountain remains visible while tiredness builds. Maintain concentration at stiles, junctions and the busy road crossing.
My route approaches the Skirrid from the back. The final climb is shorter than the Sugar Loaf ascent but very steep, and it arrives after most of the distance and ascent are already in your legs. Reaching the summit is a fantastic moment because all three Abergavenny peaks are finally complete.
Stage 4: Return to Abergavenny
Completing the third summit does not end the walk. Descend carefully and follow the route back towards Abergavenny and Fairfield. Fatigue can lead to slips and navigation mistakes during the final miles, so continue eating, drinking and checking the route until you are safely back at the car park.
Navigation and safety
- Do not attempt this route without reliable navigation. The connection between the mountains is not obvious throughout.
- Download the GPX for offline use and carry a map or a second navigation option.
- Walk with someone where possible; it is a long day and an injury could occur far from the finish.
- Take particular care at the busy road crossing.
- Expect stiles and sheep in farmland. Close gates and keep dogs under effective control.
- The Blorenge approach can be extremely muddy in winter.
- Mountain weather may differ considerably from conditions in Abergavenny.
- Turn back or shorten the day if conditions, daylight, injury or fatigue make continuing unsafe.
Training for the challenge
Prepare by completing long days containing more than one hill. A flat 20-mile walk does not reproduce 4,672 feet of ascent, while one steep mountain does not reproduce the repeated climbing and linking distances. Build both mileage and ascent gradually.
- Walk each mountain individually before joining all three.
- Progress to routes containing two or more significant climbs.
- Train on mud, steep ground, lanes and hard surfaces.
- Test the footwear, socks, pack, food and drink you intend to use.
- Practise navigating rather than following somebody throughout.
What to carry
- Broken-in walking boots or suitably supportive trail footwear
- Comfortable walking socks and a spare pair
- Waterproof jacket and trousers
- Warm layers, gloves and hats suitable for different conditions
- Enough food for a full day, eaten regularly rather than saved until exhaustion
- Water and electrolytes
- Map, downloaded GPX and backup navigation
- Fully charged phone and power bank
- Small first-aid kit, blister treatment and emergency items
- Headtorch, even when planning to finish in daylight

Abergavenny Three Peaks versus the South Wales Three Peaks Trial
This page is a self-guided route linking the three Abergavenny mountains in one day. The South Wales Three Peaks Trial is an organised annual challenge with official route options, participant instructions, checkpoints and event support. The two subjects naturally overlap, but they are not interchangeable.
If you would prefer an organised challenge—or want to compare Gold, Platinum, Silver and Bronze—use my South Wales Three Peaks Trial guide and then confirm current information with the organiser.
Final thoughts
The Abergavenny Three Peaks is a brilliant challenge, but it earns that description. The direct Blorenge climb, sweeping ascent of Sugar Loaf and steep rear approach to the Skirrid each test you differently. Add 21 miles, extensive connecting ground and difficult navigation, and it becomes a serious full-day mountain undertaking.
Train properly, take someone with you, start early and respect the conditions. If you do that, returning to Fairfield after completing all three mountains is an achievement you will remember.
