This small ecomuseum introduces Talassemtane National Park, the Rif mountain reserve that gives Chefchaouen its best hiking. The displays cover local plants, wildlife, and the park's mountain environment, but the practical value is just as important: it helps orient walkers before they head toward the trails above town or deeper into the park.
Treat it as a useful stop rather than a destination in itself. If you are planning only a quick stroll to Ras el Maa or the Spanish Mosque, you can skip it; if you are thinking about longer hikes, it is worth checking for maps and current local advice.
