Frequently Asked Questions

Can I mountain bike the St. Govans, Bosherston, and Flimston Bay loop?

No, mountain biking is generally not permitted on the Pembrokeshire Coast Path, which forms a significant portion of this loop. Cycling on the majority of the Wales Coast Path, including this section, is considered trespassing unless specific permission has been granted or it's a designated cycle route. This trail is primarily a footpath with challenging terrain unsuitable for mountain bikes.

What is the terrain like on this route?

The terrain is varied and often challenging. You'll encounter uneven ground, loose dirt, and gravel. There are also steep paths and slippery stone steps, particularly around St. Govan's Chapel. Some parts consist of stony or grass-covered tracks, which can be muddy, especially the Castlemartin Range Trail section.

What are the main points of interest along the loop?

The route offers spectacular coastal scenery and historical sites. Highlights include the picturesque Bosherston Lily Ponds, known for their wildlife, and dramatic cliff formations like Elegug Stacks, Stack Rocks, and the Green Bridge of Wales. You can also visit St. Govan's Chapel, a tiny 13th-century hermit's cell built into the cliff face, and enjoy views of Flimston Bay.

Is the trail dog-friendly?

Yes, dogs are generally welcome on the Pembrokeshire Coast Path, but they must be kept on a lead at all times. This is especially important due to the presence of livestock, cliff edges, and abundant wildlife, particularly around the Bosherston Lily Ponds and nesting seabirds on the cliffs.

Do I need a permit or pay an entrance fee to access the Pembrokeshire Coast National Park or this trail?

No, there are no specific permits or entrance fees required to access the Pembrokeshire Coast National Park or to walk this trail. However, some car parks may charge a fee.

When is the best time of year to visit this area?

Spring and summer (April to September) are generally the best times to visit for pleasant weather and to see the Bosherston Lily Ponds in full bloom. However, be aware that parts of the trail traverse the Castlemartin Firing Range, which has restricted access during live firing days. Always check opening times in advance, especially during off-peak seasons.

Where can I park to access the loop?

Parking is available at several points around the loop. Common starting points with parking include Bosherston village (near the Lily Ponds) and near St. Govan's Chapel. Be aware that parking areas can fill up quickly during peak season.

Does this trail intersect with other well-known paths?

Yes, the route primarily follows sections of the Pembrokeshire Coast Path. It also includes parts of the Castlemartin Range Trail and passes near the Bosherton Lily Ponds Trail at Stackpole Estate.

What should I know about accessing the Castlemartin Firing Range section of the trail?

A unique aspect of this loop is that parts of it traverse the Castlemartin Firing Range. Access to these sections can be restricted during live firing days for safety reasons. It is crucial to check the firing range's schedule or local signage before planning your visit to ensure the path is open. You can often find information on the Pembrokeshire County Council website or local visitor centers.

Are there any facilities like cafes or pubs near the trail?

Yes, the village of Bosherston, a common starting point for the loop, has a pub and a cafe. You may also find limited facilities in other nearby villages, but it's advisable to carry sufficient water and snacks for the duration of your walk.

Is this loop suitable for families with young children?

While sections around the Bosherston Lily Ponds are relatively easy and family-friendly, the full loop is considered moderate to hard due to its length, varied terrain, and steep ascents/descents, such as the steps to St. Govan's Chapel. It may be too challenging for very young children or those unaccustomed to long walks on uneven ground. Shorter, easier sections can be enjoyed with families.
