2. Copper Kingdom
Copper was discovered in 1768 at Mynydd Parys in Amlwch, North Wales. Over the next fifty years, this place transformed into a major mining hub in Europe. The mines attracted some of the best minds—scientists and engineers from around the world. Before the discovery, this was a small, peaceful cove. Slowly, it became the world’s largest exporter of copper.
Once the copper ore at the mines was exhausted, Amlwch witnessed the growth of a thriving shipbuilding industry. Vessels developed at the site were known for their sleek lines and speed. As a result of this legacy, there are two major Anglesey visitor attractions.
- Mynydd Parys: This is a stunner all the way. The multi-colored landscape features purple, red, and yellow rocks. Many sci-fi movies have been filmed here, as the terrain looks like the moon’s surface. The second explore-worthy spot is the mountainous heritage trails, which take you through the old mine buildings and huge man-made opencast pits.
- Porth Amlwch: Another must-visit place is Porth Amlwch. Here, you can explore original buildings like the Copper Bins, Workshop Chimneys, and the Watch House. It’s the perfect place to relax and soak up the heritage vibes while enjoying delicious snacks at the Sail Loft Visitor Centre.
3. Wild Seaweed Baths
After the walks and mine exploration, it’s time to indulge in some coastal wellness at Wild Seaweed Baths by Halen Môn. These open-air baths offer a whole new level of luxury, set against the stunning backdrop of the Menai Strait. The star of the experience is the hand-harvested seaweed, known for its skin-softening and detoxifying properties. For centuries, people – especially farmers – have bathed in seaweed for its restorative benefits. When soaked in warm water, the mineral-rich seaweed releases natural oils, traditionally believed to soothe aches and nourish dry skin.
Back in the early 19th century, there were around 300 traditional bathhouses in Ireland. Today, Halen Môn is the first Welsh company to revive this tradition, offering a private and personalized outdoor bathing experience in upcycled whiskey barrels. The water used for the baths is sustainably sourced—it’s a by-product of their sea salt harvesting process. All of this, paired with breathtaking views across an Area of Outstanding Natural Beauty, makes for an unforgettable escape.
Benefits include:
- Detoxification of the body
- Glowing, baby-soft skin enriched with natural vitamins
- Deep relaxation of mind and body in warm, soothing water
- Immersive scenic beauty at Halen Môn
- Sustainable rejuvenation—seaweed is harvested without soil, fertilizers, or freshwater
