National parks and reserves

A glacial lake at 2,034 m in the Bâlea cirque of the Făgăraș Mountains, at the top of the Transfăgărășan; reachable by car in summer and by cable car all year round.

A roughly 90 m waterfall that drops in several tiers down a limestone wall in the Rodna Mountains, above the resort of Borșa; reached by chairlift and a short forest walk.

Romania's largest natural bridge and the only one in the world carrying a public road: a 30 m limestone arch left standing after a cave roof collapsed, in the village of Ponoarele on the Mehedinți Plateau.

A natural dam lake formed in 1837, when a mountainside blocked the Bicaz valley; the trunks of the drowned forest still rise from the water, at the upper end of the Bicaz Gorge.

A roughly 30 m, two-tiered waterfall at the foot of the Vlădeasa massif, on the Stanciului valley near Răchițele; the water fans out over the rock like a veil, and in winter the frozen wall is an ice-climbing spot.

A 98-hectare former lagoon between Saturn and Venus, with reed beds, open water and sulphur springs where swans, egrets and black-winged stilts stop over; you watch it from the surrounding roads.

An 800 m wall of red clay and sandstone on the edge of Sebeș, carved by rain into columns, towers and earth pyramids, a badlands landscape rare in Romania.

A 70–80 m chain of waterfalls, with a 25 m main drop, plunging into a huge sinkhole in the Trascău Mountains and vanishing underground; seen from a wooden balcony a short walk from the road.

A two-tier waterfall of about 50 m in the Cerna Mountains, with Romania's longest free drop (~40 m), above Lake Prisaca; reached by a steep 1.5 km path from the Cerna valley road, 13 km from Băile Herculane.

A waterfall of about 15 m on the Vârciorog stream, tucked into a spruce forest below Piatra Grăitoare, near Arieșeni; reached up a wooded valley on foot or by horse cart.
