Overview
From the roadside spring and parking area at Fântâna lui Botorog, a gravel park road drops gently south into Piatra Craiului National Park and enters Prăpăstiile Zărneștilor, a former cave passage whose roof collapsed long ago, leaving the canyon open to the sky. The track follows the boulder-strewn bed of the Râul Mare, crossing the stream on stepping stones several times as the walls close in. The gorge's defining moment comes roughly a kilometer in, where the grey limestone cliffs pinch to within a few meters of the track and rise sheer for up to 200 meters on both sides, framing only a narrow ribbon of sky overhead while the Râul Mare itself vanishes beneath the rocky floor, part of the same karst plumbing that carved the small cave mouths passed a little further along the route. Past the caves the valley opens slightly and the track keeps climbing gently to a signed junction where a blue-marked path breaks off steeply toward Cabana Curmătura; this easy route turns back here and retraces the same gravel track to the trailhead. The walk stays on a wide, well-graded surface the whole way, with no scrambling or exposure, making it one of the most accessible introductions to the Piatra Craiului massif.

Access, season, and cautions
Access
From Brașov, drive southwest on DN73A via Râșnov to Zărnești, about 28 km and 35-40 minutes. From Zărnești center, continue south on the local road toward Măgura and Peștera (signposted Piatra Craiului National Park / Cabana Curmătura) for about 4 km to the Fântâna lui Botorog spring and parking area; the final stretch is unpaved gravel but passable in a standard car. Free roadside and lot parking is available at the trailhead but fills quickly on summer weekends.
No permit is required, but Piatra Craiului National Park charges a small entry fee (around 5 RON / 1 EUR per person) from 1 May to 31 October, payable at the ticket point near the trailhead; children under 14 enter free. Stay on the marked track, keep dogs leashed, and do not disturb the cave openings along the route.
Season: Walkable year-round in dry conditions, but most comfortable from April through October. Snow and ice can linger in the shaded narrows into early spring, and because much of the route follows the Râul Mare's bed, the gorge is prone to flash flooding and temporary closure after heavy rain. Summer weekends bring heavy foot and vehicle traffic on the access road; early mornings are quieter.
Cautions
- Streambed crossings on stepping stones can be slippery when the Râul Mare is running high, especially after rain
- Rockfall risk from the tall limestone walls, particularly after heavy rain or freeze-thaw cycles
- Flash flooding can raise water levels quickly in the narrows during summer storms; check the forecast before setting out
- Brown bears are present in the surrounding forest; make noise and consider hiking in a group
- Ice can form on the shaded valley floor in winter and early spring, making the gravel track slick
Waypoints
- Trailhead: Fântâna lui Botorog spring — Roadside spring, trail register, and parking area on the Zărnești-Măgura road; the national park ticket point and start of the gravel track into the gorge, at about 820 m.
- Gorge entrance / national park gate — Where the gravel road narrows and enters Piatra Craiului National Park proper; the canyon walls begin to rise on either side.
- Narrowest section of Prăpăstiile Zărneștilor — The gorge's most dramatic stretch, where sheer grey limestone walls close to within a few meters of the track and rise up to 200 m overhead.
- Cave mouths along the gorge floor — Small karst cave openings in the canyon wall, part of the same limestone plumbing where the Râul Mare disappears beneath the boulder floor.
- Turnaround: Curmătura trail junction — Signed junction where a blue-marked path climbs steeply toward Cabana Curmătura; this easy route turns back here and retraces the gravel track to the trailhead, at roughly 930 m.
