Frequently Asked Questions

Where can I park for the Heddon Valley Butterfly Walk?

Parking is available at the National Trust car park in Heddon Valley, which is the main starting point for many of the trails in the area. From there, you can access various routes, including the one leading to Heddon's Mouth.

Is the Heddon Valley Butterfly Walk dog-friendly?

Yes, the trails in Heddon Valley are generally dog-friendly. However, it's always best to keep dogs on a lead, especially due to the presence of wildlife, livestock, and unfenced cliff edges along some coastal sections. Please also be mindful of other hikers and local regulations.

When is the best time to visit the Heddon Valley Butterfly Walk?

The best time to visit depends on what you want to see. For spotting the rare High Brown Fritillary and other butterfly species, mid-June to early August is ideal. Spring offers beautiful wildflowers, while August brings blankets of purple heather. The dramatic coastal scenery is stunning year-round, but check weather conditions, especially in winter.

Are there any permits or fees required to hike in Exmoor National Park?

No, there are generally no permits or entrance fees required to access the trails within Exmoor National Park, including the Heddon Valley Butterfly Walk. However, some car parks, like the National Trust one in Heddon Valley, may charge a fee or require a National Trust membership for free parking.

Is the trail suitable for beginners or families?

The difficulty of routes in Heddon Valley varies. While some sections, like the 'Gentle walk to Heddon's Mouth' or 'Heddon's Mouth circular walk', are easy and suitable for beginners and families with all-terrain pushchairs, other parts, especially along the coast path, can be challenging with steep and uneven terrain. This specific route is rated as easy.

What is the terrain like on the trail?

The terrain is diverse, ranging from graded pathways and gravel paths along the river to more uneven tracks and footpaths. You'll encounter ancient woodlands, open moorland, and rugged coastal sections. Be prepared for some steep slopes, especially if you venture onto the coastal paths, and potentially scree slopes. Some coastal sections have unfenced cliff edges.

What wildlife and plants can I expect to see?

The valley is renowned for its butterflies, including the rare High Brown Fritillary, Dark Green Fritillary, and Silver-washed Fritillary. You might also spot otters in the river, various bird species like woodpeckers and peregrine falcons, and wildflowers in spring. In August, the moorland is covered in purple heather.

What are the main points of interest along the route?

Along the route, you can enjoy the Coastal Viewpoint with Heather and Wildlife, Exmoor National Park, offering expansive views. You'll also cross the picturesque Stone Bridge over the River Heddon. The trail also leads to Heddon's Mouth where the river meets the sea, and you can see a restored 19th-century lime kiln on the beach.

Does the trail connect with other paths?

Yes, the Heddon Valley Butterfly Walk intersects with several other notable paths. It fully covers the 'Butterfly Walk' and 'Heddon Valley coast walk' trails. Significant portions also align with the 'King Charles III England Coast Path: Minehead to Combe Martin', the 'South West Coast Path (Section 3: Lynmouth to Combe Martin)', and the 'Tarka Trail'.

Are there any easier or more accessible sections of the Heddon Valley Butterfly Walk?

Yes, for a gentler experience, consider the 'Gentle walk to Heddon's Mouth' or the 'Heddon's Mouth circular walk'. These routes follow graded paths, often alongside the River Heddon, with only slight inclines as they approach the sea. Some sections are suitable for all-terrain pushchairs and rough-terrain mobility scooters, and two all-terrain mobility trampers are available for hire locally.

Are there any facilities or places to eat near the trail?

Yes, there are facilities available in Heddon Valley. The National Trust manages a car park and often has a shop or cafe nearby. There is also a pub, The Hunter's Inn, located conveniently close to the main trailhead, offering refreshments and meals.

Trail Reviews

Monique Blansjaar
July 28, 2023, Heddon's valley

A nice walk through Heddon's valley. Relaxed walk to Heddon's mouth, the Heddon flowing into the sea. Then along the cliff up, narrow trail with steep slopes descending to the sea. The last stretch along a sheep pasture with a wide view of Heddon's valley.
