Ottersthal, France

---

Jardin Botanique du Col de Saverne, near Ottersthal in France's Alsace region, is a 2.5-hectare botanical garden and arboretum founded in 1931 by botanist Emile Walter on the Saverne Pass hillside at 335 meters altitude.

It features over 2,200 plant species organized by classification, including France's largest collection of indigenous orchids with around 20 varieties, extensive ferns, alpine plants, carnivorous species in a peat bog, and an arboretum with trees from North America, Europe, and Asia like sequoias and various conifers.

Open weekends and daily in summer with a small entry fee, the garden offers 2 km of trails for exploration amid scenic views near the "Saut du Prince Charles," though some reviews note maintenance challenges and traffic noise.
