The ecotourism route follows the mountain trails that goes through forests of oak, beech and meadows. The belvedere points, not few in number, are placed where you can admire the large boilers and Veliki Strbac, on the Serbian side of the Danube.
The Cazanele Mari takes your breath away. This is the place where you step on urgonian calcareous stones (140 millions of years old), on natural lime „sculptures”, where tertiary “şibliacuri” (vegetal associations formed mostly by lilac, Carpinus orientalis, flowering ash, smoke tree (Cotinus coggygria) are from warmer interglacial periods, is the place where the golden of the Cazane’s tulip tells you that here, in the Danube’s Cazanele Mari, is the only place in the world where it grows. This is in fact the place where “the Danube knocked and the Iron Gates opened”.
After 10-15 minutes, the ecotouristic route forks: a path weaves towards the Cazanele Mari Plateau where today it can be seen the still waters of the old Danube, once whirling like in a caldron due to the rocky relief and another path takes you right to the water level where you can caress undisturbed the Danube.
In the “Big Caldrons”, the Danube reaches its highest depth (approx 100 m).
This route crosses the Cazanele Mari and Cazanele Mici Complex Reservation. It is one of the first reservations in Romania.
Along this and all routes as well, the ecotourists must be guided by the Iron Gates Natural Park rangers because here you step on natural elements of inestimable value to Romanian and even to European geology, flora and fauna.
