Exploring Dunkery Beacon Trig Point is more than a hikeits an immersive journey into Britains topographic heritage. Unlike many modern GPS-driven navigation experiences, visiting a trig point requires intentionality, observation, and a respect for the physical landscape. This guide provides a comprehensive, step-by-step walkthrough for anyone seeking to explore this iconic landmark with accuracy, safety, and appreciation. Whether youre a seasoned hillwalker or a curious beginner, understanding how to approach this trig point will enhance your outdoor experience and deepen your connection to Britains mapping history.

Step-by-Step Guide

1. Understand the Location and Significance

Before setting out, its essential to grasp where Dunkery Beacon Trig Point is located and why it matters. Dunkery Hill rises to 519 meters (1,703 feet) above sea level and is the highest point in both Exmoor National Park and Somerset. The trig point itself is a concrete pillar, approximately 1.5 meters tall, with a brass plate engraved with its precise coordinates: 5110?45.0?N 334?40.0?W. It was installed in 1951 as part of the Third Order Triangulation network used by the Ordnance Survey to create the most accurate national map of Britain at the time.

Understanding this context transforms the visit from a simple summit walk into a meaningful encounter with scientific history. The trig point represents decades of meticulous surveying work conducted by teams on foot, using theodolites and chains to measure angles and distances across the British Isles. Reaching it is a tribute to that legacy.

2. Choose Your Starting Point

There are several access routes to Dunkery Beacon, each offering different levels of difficulty, scenery, and historical interest. The most popular and recommended starting points are:

• Porlock Weir A coastal village offering a longer but scenic route via the South West Coast Path and the historic Monks Road.
• Exford A village on the northern edge of Exmoor, providing a direct but steeper ascent via the Dunkery Beacon footpath.
• Blue Ball Inn (near Simonsbath) A well-known trailhead for the Exmoor National Park Authoritys official path to the summit.

For beginners or those seeking a balanced experience, the route from the Blue Ball Inn is ideal. Its well-marked, moderately graded, and passes through ancient woodland and open moorland, offering a gradual transition from forest to exposed summit.

3. Plan Your Route Using Reliable Mapping Tools

Modern navigation tools are invaluable, but for trig point exploration, accuracy is critical. Use the following tools to plan your route:

• Ordnance Survey Explorer Map 132 (Exmoor) The definitive paper map for this area. The trig point is clearly marked with a small triangle symbol and labeled Dunkery Beacon.
• OS Maps App The official digital version of Ordnance Survey maps, allowing offline downloads and GPS tracking.
• ViewRanger or AllTrails Community-uploaded routes often include user photos and condition reports.

Always cross-reference your digital route with the paper map. GPS signals can be unreliable on high moorland due to atmospheric interference and tree cover. The trig point is not always visible from afarrelying on map reading skills ensures you wont miss it.

4. Prepare Your Gear

Exmoors weather is notoriously changeable. Even on a clear morning, conditions can deteriorate rapidly. Your gear should reflect this unpredictability:

• Waterproof jacket and trousers Essential for sudden rain showers and wind-driven mist.
• Sturdy hiking boots With ankle support and grippy soles for muddy, rocky, and uneven terrain.
• Thermal layers Temperatures at the summit can be 510C cooler than in the valleys.
• Map and compass Even if you use GPS, a physical map and compass are non-negotiable backups.
• Headlamp or torch Daylight hours are limited in winter, and fog can descend unexpectedly.
• High-energy snacks and water A minimum of 1.5 liters per person for a 68 hour round trip.
• First aid kit Include blister care, antiseptic wipes, and emergency blanket.

Do not underestimate the exposure at the summit. Wind chill and sudden drops in visibility are common. Dress in layers you can add or remove as needed.

5. Begin Your Hike

Starting from the Blue Ball Inn, follow the signed path northward toward Dunkery Beacon. The initial stretch winds through a mix of oak and birch woodland, where the ground is soft and often muddy. Pay attention to the path markersred and white arrows on wooden posts indicate the route.

After approximately 1.5 miles, the trail emerges onto open moorland. This is where the landscape changes dramatically. The trees disappear, replaced by heather, gorse, and peat bogs. The path becomes less distinct, especially after rainfall. Here, your map and compass become vital. Use contour lines to confirm your elevation and position relative to the summit.

As you near the top, look for the distinctive concrete pillar. It is surrounded by a low stone wall, built to protect the trig point from erosion and vandalism. The brass plate may be weathered but remains legible. Take time to read it: the inscription includes the station name, elevation, and the year of installation.

6. Document Your Visit

Once youve reached the trig point, take a moment to observe and document your experience:

• Take a photo Include yourself, the trig point, and the panoramic view. This creates a personal record of your journey.
• Record the coordinates Use your GPS device or smartphone app to confirm the exact latitude and longitude. Compare it with the engraved plate.
• Sign the visitor book Some trig points have a metal box containing a logbook. If present, sign your name and date. This tradition connects you to thousands of others whove made the same journey.
• Observe the landscape From Dunkery Beacon, you can see the Bristol Channel, the Quantock Hills, and even the coast of Wales on clear days. Use your map to identify key landmarks.

These actions transform your visit from a checklist into a meaningful rituala personal acknowledgment of the lands history and your place within it.

7. Descend Safely

Descending can be more dangerous than ascending, especially in poor visibility or on wet terrain. Always retrace your steps along the same route unless you are experienced and have a pre-planned alternative descent.

Watch for:

• Slippery rocks Especially near the summit where the path is worn smooth by foot traffic.
• Hidden gullies The moorland is riddled with drainage channels that can be obscured by heather.
• Changing light Sunset occurs quickly on the moor. Plan your descent to finish before dusk.

If you become disoriented, stop. Use your compass to reorient yourself to your route. Do not attempt to cut across unfamiliar terrain.

8. Reflect and Share

After your visit, take time to reflect. What did you learn? How did the landscape feel? Did the trig points history resonate with you?

Consider sharing your experience responsibly:

• Leave no trace Remove all litter, including biodegradable items like fruit peels.
• Respect wildlife Exmoor is home to red deer, ponies, and rare birds. Keep your distance.
• Post a review or blog Help others plan their visit with honest, detailed accounts. Avoid revealing exact GPS coordinates publicly to prevent overcrowding or vandalism.

Best Practices

1. Respect the Trig Point as a Historical Monument

Trig points are not decorative objectsthey are scientific instruments. Avoid climbing on them, scratching the brass plate, or attempting to move them. Many trig points have been damaged by souvenir hunters. The Ordnance Survey and local conservation groups work hard to preserve these markers. Your respect ensures they remain intact for future explorers.

2. Visit During Off-Peak Times

Dunkery Beacon is popular, especially on weekends and holidays. To enhance your experience and reduce environmental impact, consider visiting on a weekday or during the shoulder seasons (AprilMay or SeptemberOctober). Youll enjoy quieter trails, better photography conditions, and a more contemplative atmosphere.

3. Learn Basic Map and Compass Skills

While GPS is convenient, its not infallible. Battery failure, signal loss, and software glitches can leave you stranded. Invest time in learning how to:

• Read contour lines to identify elevation changes.
• Use a compass to take a bearing and follow it.
• Triangulate your position using three visible landmarks.

Many local outdoor centers and the Ramblers Association offer free or low-cost map-reading workshops. These skills are invaluable not just for trig point hunting but for all outdoor navigation.

4. Be Weather-Aware

Exmoor is notorious for rapid weather shifts. Always check the forecast from the Met Office and Mountain Weather Information Service (MWIS) before departure. Pay attention to:

• Wind speed and direction
• Precipitation probability
• Visibility forecast

If fog or heavy rain is predicted, consider postponing your trip. The summit can become disorienting and hazardous in low visibility.

5. Travel in Groups When Possible

While solo hiking is a personal choice, trig point excursions benefit from companionship. A group provides mutual support in case of injury, fatigue, or getting lost. At minimum, inform someone of your planned route and expected return time.

6. Support Local Conservation Efforts

Exmoor National Park relies on volunteers and donations to maintain trails and protect habitats. Consider donating to the Exmoor National Park Authority or volunteering for a trail maintenance day. Your contribution helps preserve the very landscape you come to explore.

7. Avoid Disturbing the Ecosystem

Dunkery Hills moorland is a protected habitat for rare plants like heather, bilberry, and the elusive Dartford warbler. Stick to marked paths to prevent erosion and habitat fragmentation. Do not pick flowers, dig into peat, or feed wildlife.

Real Examples

Example 1: The First-Time Explorer

Emma, a 28-year-old teacher from Bristol, had never hiked a trig point before. Inspired by a documentary on British mapping, she planned a solo trip to Dunkery Beacon using only her smartphone and a printed OS map. She started from the Blue Ball Inn on a crisp October morning. The woodland trail was peaceful, but as she reached the moor, a sudden mist rolled in. Her phone GPS flickered. Panicked, she pulled out her compass, aligned it with the map, and followed the contour lines. She reached the trig point 45 minutes later, just as the fog lifted. She signed the logbook, took a photo, and descended safely. It felt like Id stepped into a forgotten chapter of British history, she wrote in her journal. The trig point wasnt just a markerit was a message from the past.

Example 2: The Family Adventure

The Patel family from Taunton brought their two children, ages 9 and 12, to Dunkery Beacon as part of a Geography Week project. They used a family-friendly route from Porlock Weir, which included stops at historic stone circles and ancient drovers roads. The children used a simple compass app to find bearings and kept a field notebook recording landmarks. At the summit, they compared their GPS readings with the brass plate. We learned that maps arent just picturestheyre measurements, said the 12-year-old. The family later presented their findings at school, winning the regional science fair.

Example 3: The Historical Researcher

Dr. Alan Mercer, a professor of cartographic history, visited Dunkery Beacon to photograph the trig points original installation markings. He cross-referenced his findings with Ordnance Survey archives from 1951 and discovered that the pillar had been installed by a team that included his grandfather, a surveyor who had worked on the Third Order network. He published a paper titled Personal Landscapes: Trig Points as Family Archives, which sparked renewed interest in the human stories behind Britains mapping legacy. His visit led to a local heritage plaque being installed near the trig point, honoring the surveyors who made it possible.

Example 4: The Geocachers Quest

James, a geocacher from Devon, had collected over 1,200 caches. His final goal was to find a Trig Point Challenge cache hidden near Dunkery Beacon. The cache required him to photograph the trig point, record its coordinates, and answer a question about its construction date. He hiked the route in winter, navigating through snow and ice. It wasnt about the prize, he said. It was about understanding why this little concrete pillar mattered. I now have a new hobby: visiting every trig point in Somerset.
