A lovely little tucked away quarry which is great to have a dip mid run. The water is freezing though so bare that in mind! Great area for running and exploring the Presellis

A great place to view western Pembrokeshire. The bridleway descent to the north west is very overgrown though.

A wonderfully wild bridleway that runs along the summit ridge of the Preseli hills. Best ridden from west to east so that it's predominantly downhill and much better in dry weather, it gets a bit boggy in the winter.

Ambleston's undulating terrain and proximity to the Pembrokeshire Coast National Park make it enjoyable throughout much of the year. Spring and autumn generally offer pleasant temperatures and vibrant scenery. While summer is popular, trails can be busier. Winter riding is possible, but be prepared for potentially wet and muddy conditions, especially on unpaved sections, and check local weather forecasts.
When cycling within the Pembrokeshire Coast National Park, which is close to Ambleston, it's important to stick to designated bridleways and byways. Respect private land, keep gates closed, and be mindful of walkers, horse riders, and livestock. Always follow the Countryside Code to ensure a safe and enjoyable experience for everyone and to protect the natural environment.
While the Llys-y-Frân Reservoir Cycle Trail can be popular, routes that venture further into the Preseli Hills, such as the Preseli Hills & Llys-y-frân dam loop or the Pantmaenog Gravel Tracks – Foel Feddau summit loop from Rosebush, tend to be less crowded due to their longer distances and more challenging nature. Exploring these routes during off-peak hours or weekdays can also enhance the sense of solitude.
Many trails in the Ambleston area, particularly those on public bridleways and byways, are generally dog-friendly. However, dogs should always be kept under close control, preferably on a lead, especially when passing through farmland with livestock or in areas with ground-nesting birds. Always clean up after your dog. Specific rules may apply to certain managed sites like Llys y Frân Country Park, so it's advisable to check their guidelines directly.
