    Hiking

    The blue lagoon is a former slate quarry. These days, it's a beautiful place with deep blue water. The lagoon is a great place for water sports, including swimming and paddleboarding.

    You can park at Abereiddy Beach car park which is a short walk around the corner. It costs £4 between 8am-5pm and is unattended outside these hours. Alternatively, it's a great place to stop off along the coastal path.

    Hiking

    The beach is closed during seal pupping season, but you can see them from above (please take care. The cliffs are very steep with a large drop!!).

    Embark on the Porthgain to Abereiddi Coastal Walk, an easy hiking route that offers a refreshing journey along the Pembrokeshire coastline. This trail spans 4.1 miles (6.6 km) with an elevation gain of 308 feet (94 metres), typically taking about 1 hour and 48 minutes to complete. You will experience rugged cliffs and open grasslands, leading you to the striking Blue Lagoon at Abereiddi, a former slate quarry known for its vivid, shimmering water.

    To begin your adventure, you can park conveniently at Abereiddi Beach, which serves as an accessible starting point for the route. Although the trail is rated easy, be aware that it includes some sections with steep climbs, descents, steps, and stiles, which may feel more moderate in places. Always exercise caution when you are near cliff edges and any overhangs along the path. This makes it a great choice for a shorter outing, perhaps in the morning or late afternoon.

    Beyond its natural beauty, the route also tells a story of the region's industrial past. As you hike, you will encounter remnants of Porthgain's history, including impressive brick hoppers and quarry ruins that speak to its busy fishing and quarrying days. Keep an eye out for diverse wildlife, such as choughs, which are often spotted in this coastal environment, adding another layer of interest to your walk.
