Izvorul Muntelui Lake — also called Lacul Bicaz — is one of Romania's largest reservoirs, a long, serpentine stretch of water cradled between the forested ridges of the Eastern Carpathians. Whether you arrive for the dramatic scenery, the birdlife, or simply to breathe the mountain air beside a vast expanse of water, this place delivers something genuinely memorable.

The lake runs roughly 35 km from northwest to southeast, tracing the drowned valley of the Bistrița River. Steep, forest-clad slopes drop straight to the waterline, and the lake level can vary by as much as 25–30 metres over the year, constantly reshaping the shoreline. Summer brings shimmering reflections and boat trips; autumn turns the surrounding hills gold and amber; winter wraps the surface in mist. A 150-hectare protected aquatic nature reserve has been established on the right bank in the Izvorul Alb area. The lake is home to trout, chub, barbel, huchen and other species, making it popular with anglers.

• From Bicaz — road DN15 climbs over the dam crest and runs along the left bank of the lake; the most convenient approach, with easy parking near the tourist harbour.
• From Toplița — DN15 from the northwest along the right bank; ideal for visitors arriving from Transylvania.
• By train: Bicaz station, line 509 — a scenic, car-free option from Piatra Neamț.

• The aquatic nature reserve (150 ha, Izvorul Alb area) has been protected since 2000 — fishing and water activities are restricted within this zone.
• A tourist harbour near the dam on the left bank offers boat and pedalo hire, wooden chalets and a floating hotel.
• The trout farm in Potoci and the Alexandru Ioan Cuza University Biological Research Station are open to visitors with advance arrangement.

The 127-metre-high Bicaz Dam, completed in 1960, involved the forced displacement of 22 villages and over 18,000 people — a heavy human cost commemorated by a memorial cross at the dam's end, and by the paintings of artist Iulia Hălăucescu, known as 'the lady of Romanian watercolour'.
