Retezat National Park, near Râu de Mori in Romania, is a prime destination for nature lovers and hikers, famous for its rugged peaks, glacial lakes, and diverse flora and fauna. The park is accessible by car, with the nearest airports in Timișoara or Sibiu, and offers marked hiking trails ranging in difficulty. It's best to plan your visit between late spring and early autumn, as snow can restrict access in winter. Entry fees are modest, around 10 RON (approx. €2) per day, and guided tours are recommended for an enriched experience, though it’s feasible to visit solo with adequate preparation. Allow at least 2-3 days to explore major highlights, especially if you plan to hike to the park's highest peak, Peleaga, which takes about 8-10 hours round trip. Accommodations range from camping sites to rustic lodges, so booking in advance is wise, especially in peak season.
