Rhobell Fawr & Dduallt

Rhobell Fawr and Dduallt: The Volcanic Heartland 2026 Open Group Dates: Saturday 4th April 2026 Saturday 22nd August 2026 £75 per person | Small Group Journey | Guaranteed to Run Rhobell Fawr and Dduallt are personal favorites of Mountain Craft. Despite being central and prominent within Eryri, these peaks remain far quieter than almost every other major summit in the region. Rhobell Fawr is the rugged remains of an ancient volcano, while its sister, Dduallt, forms a standalone ridge with a dramatic, rocky eastern face. THE ROUTE: Meeting near Coed y Brenin, we travel to the remote road end at Cwm yr Allt Lwyd to begin our journey. While the 13km distance and 1000m of ascent seem modest, the terrain is intricate and challenging. We follow the Afon Mawddach before ascending the unspoilt north ridge of Dduallt. After traversing the ridge and passing through local woodland, we follow ancient drystone walls to the summit of Rhobell Fawr, returning via a series of smaller mountain tops. CORE HIGHLIGHTS: The Volcanic Peak: Explore the unique geology of one of the most significant ancient volcanic sites in North Wales. Source of the Rivers: Walk directly past the headwaters of two major Welsh rivers, the Dee and the Mawddach. Central Panoramas: Experience an elevated, unique perspective looking into the very heart of the National Park from a peaceful vantage point. WHY BOOK RHOBELL FAWR AND DDUALLT? The Solitude Factor: These mountains are remarkably underrated. You will be amazed by the quiet and isolation found here, even during the peak summer season. Expert Coaching: This route requires careful route finding around rocks and streams, making it the perfect environment to hone your off-path navigation and movement skills. Guaranteed to Run: Your booking is secure. We do not cancel due to low participant numbers, so you can plan your August adventure with peace of mind.
