A lovely little cafe for a quick pit stop en route

Low bridge - probably best to lower your saddle - or even better - walk your bike under this bridge

Well maintained tow path and is quite tranquil

Nice gravel track down to the reservoir with lovely views. Track down can get muddy but good fun. Do-able on a gravel bike

Easy walking along the Eastern and Southern edges of the reservoir, courtesy of the Gower Way (a 35-mile path linking Penller Castell to Rhossili if you fancy stretching your legs a little further). Fantastic views.

Set amongst the stunning mountain scenery of the Mawr, the Lower Lliw reservoir is surrounded by a variety of habitats including bracken, scrub, grass and woodland, supporting a variety of wildlife. If you're into birding, keep an eye out for Peregrine, Kestrel, Raven, Wheatear, Meadow Pipit, Skylark, Whinchat, Red Kite and Curlew - which have all been spotted here. There is an accessible path to the South of Lower Lliw Reservoir that will take you all the way to the Upper Reservoir. The circular path closer to the shore-line features steep steps in places.

The landscape is primarily defined by gentle reservoir paths and quiet woodlands with relatively low elevation changes, making it accessible for most walkers. Out of over 160 routes, the vast majority are rated as easy or moderate, with only a few classified as difficult.

Are there any easy hikes suitable for families?

Are dogs allowed on the trails?

Many of the trails around the reservoirs and through the woodlands are suitable for walking with dogs. However, you will be passing through areas with wildlife and potentially livestock, so it's important to keep your dog under control, especially on paths like the Upper Lliw Reservoir loop from Rhyd-y-fro. Always check for local signage regarding leads.

Where can I park for the reservoir walks?

For hikes around the Lliw Reservoirs, there is a dedicated car park at the Lower Lliw Reservoir. This serves as a convenient starting point for many popular routes, including the trail that connects the lower and upper reservoirs. Arrive early on sunny weekends as it can get busy.

Are there any good circular walks?

The area is perfect for circular hikes. Most of the popular routes are loops that bring you back to your starting point. A great example is the From Lower Lliw Reservoir to Upper Lliw Reservoir loop, which provides a satisfying circuit connecting both reservoirs.

What are the most scenic parts of the hikes in Mawr?

The main scenic draws are the tranquil waters of the Lower and Upper Lliw Reservoirs. The paths that follow the shorelines offer beautiful, reflective views.

What should I wear for hiking in Mawr?

Sturdy, comfortable walking shoes are recommended as some paths can be uneven or muddy, especially after rain. As with any hike in Wales, it's wise to wear layers and bring a waterproof jacket, as the weather can change quickly. The terrain isn't overly demanding, so heavy-duty mountaineering gear is not necessary for most trails.

Are there any longer hikes available?
