Le sentier karstique, La Romieu
All yearEight kilometres with over two hundred metres of climb, which is the steepest thing on this list — the Gers does not usually do steep. An interpretive trail on underground water, caves and cliffs, so there is something to read at intervals. Combines with the collegiate church and the cats for a full morning. Allow nearer three hours than the distance suggests.
