The Mach Loop
Welcome to Dolgellau, a picturesque town nestled in the heart of Eryri National Park, surrounded by stunning mountain ranges, rivers, and forests.
The Mach Loop is a spectacular attraction near Dolgellau
One of the most increasingly popular attractions in this area is the Mach Loop, a low-level flying area with aircraft regularly going past Penybryn Cottage and viewpoints in the same valley (Cad West / East).
The Mach Loop is a series of valleys and mountains that provide challenging terrain for pilots to train their low-level flying skills, in particular for fighter aircraft. As such, it is one of the best places to witness the sheer power and agility of military aircraft up close.

Accommodation near The Mach Loop
If you are looking for self-catering accommodation near the Mach Loop, Penybryn Cottage is private and detached and is located in the same valley as one of the best viewing spots for the Mach Loop – the Cad West viewing area.
From here you can witness the aircraft as they fly past at breakneck speed, weaving their way through the valleys and mountains with precision and skill. You will need a reasonable level of fitness to hike up to Cad West (or Cad East) and there is limited parking for Cad West (go early).
The Mach Loop is an experience you’ll never forget
The Mach Loop is not just a sight to behold; it is also an experience you will never forget. The adrenaline rush from seeing the aircraft fly past at such close range is truly unforgettable. You can bring your own binoculars and cameras to capture the moment and take home lasting memories. Please be advised that drones are not allowed at Penybryn Cottage due to the valley being a low-fly zone.
