Halen Môn's Inaugural Seaweed Festival
This May we're holding our very first seaweed festival here at Halen Môn, showcasing the magic of this incredible, under-celebrated natural resource. Enjoy shoreline wanderings and hands-on experiences, from foraging to gardening, fermenting to crafting — all led by local expert guides.
Book workshops on foraging, pressing and fermenting, and learn all about how this delicious and nutrient-rich resource can be used in a myriad of ways.
It's the perfect opportunity to book in for one of our award-winning Wild Môn Seaweed Baths too, and soak up the mineral-dense oils of seaweed in warm 40°C luxury.
Please note tickets are required for each individual event. See the bottom of this page for T's and C's.
