This isn’t a hike, it’s a stroll — and that’s exactly the point. Five flat kilometres from Lisle-sur-Tarn, doable with children, a pushchair or at the end of the day, linking the best of the bastide: its arcaded square, the line of the Tarn and the lac de Bellevue.
You set off from Place Paul-Saissac, a huge rectangle lined with half-timbered houses and brick arcades — one of the largest bastide squares in the South-West. From there you drop towards the river and the old port, then follow the Tarn to the lac de Bellevue, a former gravel lake turned walking spot where irises flower in spring. The return is an easy amble back through the lanes.
Nothing demanding here: no climbing, grassy or surfaced paths, shade near the water. It’s the ideal outing for hot summer days, when the slopes bake in the sun — here you stay by the water, and the bastide is never far for a pause in the shade of the arcades.
