This walk takes in three reservoirs (starting from the Visitor Centre) and at 12 miles it could put some people off. But before you panic, remember this - just like all our long walks, this can be broken down into smaller, more foot-friendly paths. In fact, you could easily plan to walk this place one reservoir at a time and still find plenty to enjoy here.

The path around Caban Coch reservoir is highly accessible. Experienced walkers may find it a bit easy, even boring, but the views are great and it does get more difficult later on.

When later deciding whether to follow the gentle path around the reservoir to Pen-y-garreg dam, and then join the main road, or to head for the hills above, remember that while the gradient might make your thighs burn it really is worth the effort.

You'll be faced with some truly awe-inspiring scenery. Up here you're very exposed and, the stronger the wind, the bigger the chill factor - so be aware of the cold when packing your rucksack.

As you get to the dam at Pen- y-garreg you're faced with a long 5 mile walk back to the Visitor Centre. You may be lucky and get to catch the Post Bus here, which can take you back, but as it only runs once a day it's not really a safe bet.

However, there are plenty of car parks along the way - so if you don't fancy a long march back, then some forward planning is recommended.

Derek Brockway says...
Part of this walk is along the Elan Valley Trail which is easy to follow: a surfaced path, suitable for everyone including people in wheelchairs, pushchairs, cyclists and horse riders.

Hanging oak forests, rocky outcrops and farmland make this the best place in the country to see the famous Red Kite. You may see one floating in the air but if not you could always go on a bird safari! Pop into the visitor centre for details.

Sorcha Lewis - Countryside Officer says...
Enjoy the typical Welsh sessile oak woodlands with pied flycatchers, wood warblers and redstarts for company.

Each time you take a breather and look back over your shoulder, the views become increasingly spectacular.

Reaching the summit and heading towards the forestry, the breathtaking landscape overlooking Craig Goch reservoir and the hills of the Cambrian mountains comes into view.

Whatever the season or the weather, the view from this hilltop remains beautiful.
