Recorded for this area
The Forest the War Years Planted“At Tan y Coed, huge Douglas firs shade the picnic area. The forest around them has a surprisingly recent story. The Forestry Commission began planting here after the First World War to build Britain's timber reserve.”

Trail guide
A circular 1.1 mile / 1.8 km loop on red waymarkers, starting and finishing at the Tan y Coed car park in Dyfi Forest. Allow about an hour, more if children are working through the numbered animal clues. Graded moderate, and genuinely so: this is a small walk with real steps and gradient in it, not a level stroll.
From the car park the route climbs away on forest road, then swaps onto rougher unmade rights of way through conifers and beech woodland. It drops to the Nant Cwmcadian riverside, reaches the Pistyll Nant Cwmcadian waterfall, threads through the rock passage, and returns to the car park on the marked loop, sharing some paths with the longer trail at the site.
The waterfall and the stretch beside the stream are the reward. The rest is quiet, close-canopy woodland with the sound of moving water below you for a good part of the way.
There are two benches and two picnic tables along the way, which suits a slow family pace with pauses.
Numbered posts set animal puzzles, covering creatures such as robin, squirrel, owl, woodpecker, fox, hazel dormouse, buzzard and badger. Treat them as prompts for looking and listening rather than a promise of sightings. Realistically you may hear more than you see: small birds in the canopy, and occasional movement in the leaf litter.
The car park is signed from the A487 between Machynlleth and Corris, roughly 3.5 miles north of Machynlleth, on the left. There is free parking, blue-badge spaces and toilets, and no overnight parking. Dogs are welcome at the site; keep yours under control near the river and on the narrow, uneven stretches where there is little room to manoeuvre around other walkers.
The separate Tan y Coed Trail starts from the same car park and runs about 2.3 km with more climbing. Pick that one if you want a longer forest walk, or link a visit to both if you have a half day and legs for the gradient.
