Planning
Filling Water on the Durmitor Ring: Which Springs Run in Late August and Which Are Dry
ByThe 3E Travel team · · 7 min read
A spring-by-spring account of what's still flowing along the 76 km Durmitor Ring after a dry 2026 summer — and the two places you can count on to refill.
If you are driving or cycling the Durmitor Ring in late August, plan your water around one fact: by this point in a dry year, most of the small trickles marked on hiking maps are gone. Durmitor is credited with 748 springs, which sounds like you will never run short. Along the 76 km loop road itself, only a couple of those are both reliable and easy to reach without a long detour.
2026 was a dry summer across much of Europe — low soil moisture, low river flows, little relief until the very end of the month. That matters here. A spring that is 'active till September' in a normal year can run to a damp patch by the third week of August when the snowfields that feed it melted out early. Here is what I actually see when I refill bottles on this route.
Studenac, near Sedlo Pass — the one you can count on
The Studenac spring sits on the macadam section of the loop, on the Žabljak–Virak–Sedlo–Dobri Do–Todorov Do–Trsa stretch, near the Sedlo Pass at 1,907 m. It runs from spring through to winter, which is the key phrase. It is fed deep enough that late-summer drought barely touches it. In late August it still comes out cold and steady — cold enough that you feel it on your teeth.
This is the spring to build your plan around. If you are cycling the high section, fill everything here before you commit to the long descent. If you are driving counterclockwise, as the Panoramic Roads brochure recommends, you hit this part in the back half of the loop, roughly two hours in with stops.
Dobri Do valley — the marginal one
The spring in the Dobri Do valley, around 1,838 m and close to Sedlo Pass, is described as active until September. In a wet year that holds. In 2026 I would not rely on it in late August. By then it is the first of the high-valley sources to fade, and I have arrived to find it down to a seep you cannot fill a bottle from. Treat Dobri Do as a bonus, not a plan. If it is running, good; if not, Studenac is a short way along the same road.
The Black Lake end of the loop
At the Žabljak end, the roughly 4.7 km circular trail around Black Lake (Crno jezero, 1,416 m) passes several small springs running from the forested slopes. These are more sheltered and shaded than the high-valley sources, so they hold better into late summer, though flow still varies. There is a quirk worth knowing: a sign on the lake shore explains that depending on the season, water flows from the small lake into the large one and out via a stream, or reverses and drains through an underground outlet. It is a limestone system, and the whole thing breathes with the water table.
Because Black Lake is a 10-minute walk from the ticket office and only 3 km from town, this is the easiest place to top up at the start or end. If you are doing the loop as a day drive, start full here rather than trusting the gravel-road springs.
Late-August reliability, spring by spring
Durmitor Ring water sources in late August of a dry year (counterclockwise order)
| Source | Elevation | Late-Aug 2026 status | Notes |
|---|---|---|---|
| Black Lake circuit springs | ~1,416 m | Usually flowing | Shaded, variable; easiest top-up near town |
| Dobri Do valley spring | ~1,838 m | Marginal / often dry | 'Active till September' in a normal year; don't rely on it |
| Studenac, near Sedlo | ~1,907 m | Flowing, cold | Most reliable on the loop; fill here before descending |
Fees, access and the practical bits
Park entry is €5 per person per day in 2026, with the daily ticket price held at five euros by the current decision on fees; an annual pass for all Montenegrin national parks is €13.50. The two main control points are at Black Lake and the base of Sušica Canyon, and rangers patrol the busier trailheads. The visitor-centre-only ticket is €1.
Parking is a small inconsistency to watch: the official price list gives €1.00/hour for a passenger car at the Black Lake centre, but a 2026 visitor reported being charged €3/hour. Bring a few euros in coins either way. The loop road is not suitable for vehicles over 7 metres, and campervans should go clockwise rather than the usual counterclockwise. The road opened for the 2026 season on 6 June, including the Pišće–Todorov Do–Sedlo section back toward Žabljak.
One honest note on the route itself: the Ćurevac viewpoint detour (1,626 m, about 7.6 km and 20 minutes from Žabljak) is worth it for the Tara Canyon view, but it adds nothing in terms of water. Do it for the view, not as a refill stop.
Can I drink the Durmitor Ring spring water without treating it?
The named mountain springs like Studenac near Sedlo are cold and clean, and people drink them untreated. If you have a sensitive stomach or are filling from a slow seep rather than a clear running source, a filter or purification tablet is cheap insurance.
How much water should I carry for the full 76 km loop?
If you're driving, two litres per person covers you comfortably with Studenac and the Black Lake springs as backups. If you're cycling the high section, carry at least two litres and fill everything at Studenac before the descent, because the valley springs may be dry.
Is there anywhere to buy water on the loop?
Only Žabljak has shops and the single fuel station on the route. Villages like Trsa, Mala Crna Gora and Pišće are tiny and have no reliable shop. Buy what you need in town before you leave.
Why are some springs dry in late August when Durmitor has 748 of them?
Most of those springs are scattered across the massif, not on the loop road, and many are snowmelt-fed. After a dry summer with early snowmelt, the shallow high-valley sources fade first. The deep, steady ones like Studenac keep running from spring to winter.
Short version: fill in Žabljak, top up at Studenac near Sedlo, and treat everything in between as a maybe. Check with the Žabljak tourist office for any mid-season closure of the Sedlo section before you set off, and carry the extra litre. In late August, that is the difference between an easy loop and a thirsty one.
