The Pitlochry fish ladder runs alongside Pitlochry Dam, a ten-minute walk from the town centre, and it exists to solve a problem the dam created.
When the Tummel–Garry hydro-electric scheme was built in the late 1940s, damming the river to create Loch Faskally, it blocked the route that Atlantic salmon had used to reach their spawning grounds upstream. The North of Scotland Hydro-Electric Board was legally obliged to provide a way past.
The answer was a fish ladder: 34 linked pools rising in steps around the dam, each one a short jump above the last, so that a salmon can climb 16 metres of dam a metre at a time.
Around 5,000 salmon use the ladder in a typical year.
The season runs from roughly April to October, with the heaviest movement usually May to September. Numbers depend on river conditions — a spate brings fish through, a long dry spell does not — so there is no guarantee on any given day. Visitors arriving early in the season regularly report seeing none.
The observation chamber — the glass window that let visitors look directly into a pool — has been closed since 2019 on access and safety grounds, and this catches people out.
What replaced it is arguably better: underwater cameras in the ladder with live feeds in the visitor centre, plus a counter showing how many fish have passed. You watch the salmon in the water rather than through a small window, and you get the running total.
Pitlochry Dam Visitor Centre, opened in 2017, is free and rather good — displays on the hydro scheme, the engineering, the “Power from the Glens” programme that electrified the Highlands after the war, and the fish.
There is a café with a view over the dam and the loch, and a shop.
The dam itself can be walked across, giving a view down the Tummel gorge one way and along Loch Faskally the other.
The honest description: it is a beautiful spot with interesting infrastructure, and whether you see a fish is luck.
There is something genuinely appealing about the setting — dark swirling pools below the dam, the concrete and steel of a late-1940s power station, the river running fast, and the loch behind. It is a good place to be for half an hour regardless of what is in the water.
Time: thirty minutes to an hour, plus the walk.
The ladder is the start of the best walk in Pitlochry: round Loch Faskally, about 12 kilometres, crossing at the dam and at Coronation Bridge, through Faskally Wood and back along the far shore.
A shorter version — dam, Faskally Wood, Loch Dunmore and back — takes about two hours.
Free — both the fish ladder and the visitor centre.
Parking: at the dam, charged.
Facilities: café, shop, toilets at the visitor centre.
Access: the visitor centre and dam walkway are accessible; the path alongside the ladder involves steps and slopes.
Getting there: a ten-minute walk from Pitlochry town centre, downhill on the way there.
Sometimes. The season runs roughly April to October with peak movement May to September, and it depends on river conditions. Around 5,000 fish use the ladder a year.
No — the observation chamber closed in 2019. Live underwater camera feeds in the visitor centre replaced it.
Yes, both the ladder and the visitor centre. Parking is charged.
Thirty-four, rising about 16 metres round the dam.
Walk the dam, visit the free hydro exhibition, and take the loop round Loch Faskally — about 12 kilometres, or two hours for the short version.
