Count István Ambrózy-Migazzi, the founder, was a pioneer of the 'semper virens' (evergreen) philosophy, aiming for a garden that remains green year-round.
The arboretum's collection contains over 300 different species and varieties of rhododendrons.
It features a special section dedicated to giant sequoias, which were planted as saplings in the early 20th century.
The location was chosen specifically for its acidic soil, which is ideal for cultivating ericaceous plants like rhododendrons.
The arboretum includes a unique 'transylvanian-style' wooden gate marking the entrance to the forest sections.
It is home to several hundred-year-old pine and spruce specimens that provide a dense canopy for the undergrowth.
The site functions as a protected nature reserve, playing a critical role in local forest biodiversity conservation.
Jeli Arboretum Nature Reserve is a renowned botanical garden in Kám, Hungary, specifically celebrated for its extensive collection of rhododendrons. Established in 1922 by Count István Ambrózy-Migazzi, the arboretum serves as a primary hub for studying plant acclimatization. The garden spans approximately 75 hectares and features a unique microclimate that allows Mediterranean and exotic species to thrive alongside native flora. The landscape includes a mix of dense forest areas, winding paths, and a dedicated sequoia grove. Visitors can explore distinct botanical sections connected by wooden bridges and narrow trails. The garden is managed by the Szombathely Forestry Corporation and functions as an active research site. It is recognized as one of the most significant dendrological collections in Central Europe.

Bring a high-quality camera with a macro lens, especially during the spring bloom period.
Wear comfortable, water-resistant hiking boots as the paths can be muddy after rain.
Visit on a weekday to avoid peak weekend crowds during the height of the rhododendron flowering season.
Visiting outside of the late spring bloom season if your primary goal is to see the rhododendrons in flower.
The arboretum is highly seasonal; the main gate operates primarily from spring through autumn and closes during the winter months.
Stick strictly to marked trails to protect the fragile root systems of the rhododendrons; do not pick flowers or plants.
