Tinée

Tinée venue image

The Tinée rises at the Col de la Bonette — which at 2,715 metres is either the highest paved road in France or the second-highest, depending on who is counting and how — and runs south-west through a long Mercantour valley to join the Var below Pont de la Mescla.

How to fish it · for Brown Trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
Water at 19.2°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.

About this water

The Tinée rises at the Col de la Bonette — which at 2,715 metres is either the highest paved road in France or the second-highest, depending on who is counting and how — and runs south-west through a long Mercantour valley to join the Var below Pont de la Mescla. It is as wild as French trout fishing gets outside the Pyrenees: granite bedrock, cold alpine water, small wild brown trout in tumbling pocket water, and the kind of scenery that makes you forget to fish. Storm Alex in October 2020 hit the Tinée hard. The valley lost roads, houses, and in some places whole hamlets; the river itself was reshaped in several reaches by the force of the flood. The fishing has recovered, and the trout populations with it, but the landscape still bears the scars, and some access points have had to be rebuilt. It is worth mentioning because honesty is better than pretending. The Tinée is still a beautiful river to fish — more so, perhaps, because you know what it went through. Fish it from late May (earlier the snowmelt is too heavy) through September. Pocket water tactics, short rods, and an eye on the weather: the Mercantour generates storms fast.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
A drop and clear would lift the flow and clarity scores.
The dawn and dusk windows score higher than the midday lull.
