If you stop in Porrentruy, if you are a herb, plant and flower enthusiast, you should definitely pay a visit to the Parc du Jardin Botanique. After the botanical garden in Basel, it is the second oldest in Switzerland. It is striking that in addition to the almost inexhaustible variety of plants, one or the other sundial on several house fronts shows the time in a shadowy way. A particularly idiosyncratic and modern example can be seen at the end of the park when you enter the area through the main portal. Right next to the botanical garden, there is a public car park that is subject to a fee. From the botanical garden, you can continue your journey of discovery in the direction of the old town, or pay your respects to the castle above the city.
