Einot Tzukim (Ein Feshkha) Nature Reserve

What a ticket buys is the central visitors' section: a car park, a service centre, the visitor centre, picnic areas shaded by date palms and tamarisks, several wading pools full all year, and one deeper pool. A marked circuit links the pools and the archaeological site, with interpretation boards along the way. The parks authority's Hebrew brochure gives it as half an hour to an hour and a half, and says it can be broken up with a swim.

North of that is the closed reserve, which the public never sees. An older parks authority page, cited by Wikipedia, put it at about 2,700 dunams against the visitors' section's 500, with entry by special invitation for scientists. The part of the oasis with the most to lose is the part with nobody in it.

South is the Hidden Reserve, and it is the reason to come on a Friday or a Saturday. The parks authority describes a walking route between clear pools and heavy vegetation, and its 2025 brochure lists guided visits at 10:00 and 14:00 on Fridays, at 10:00, 12:00 and 14:00 on Saturdays, and hourly on festivals from 10:00 to 15:00, with Arabic-language tours on Fridays at 11:00. Those weekend tours are free and are for individual visitors. Groups, and individuals who want the Hidden Reserve midweek, must bring a guide from the reserve's approved list.

The fourth part of the reserve is a view rather than a place. A lookout faces the retreating shore, and the parks authority is blunt about why it is only a lookout: the coast has gone back more than a kilometre, and the exposed bed is unstable and sinkhole-prone.

• Closed reserve, north: about 2,700 dunams, scientists by invitation only
• Visitors' reserve, centre: about 500 dunams, pools, trail, archaeological site, visitor centre
• Hidden Reserve, south: guided only; free tours at weekends and festivals, an approved guide midweek
• The Dead Sea itself: off limits, and the reserve's rules say so in the first line

The parks authority explains the name from the setting: Ein Feshkha, it says, means split or cloven, for the rift the oasis sits in and the springs that break out of it. The Palestine Exploration Fund's name lists, compiled by Edward Henry Palmer in 1881, instead record Feshkhah as either a personal name or a word with no meaning at all.

Why the water is salty has two candidate explanations and the parks authority prints both: fresh water mixing with ancient brines held in deep rock, and fresh water mixing with Dead Sea water left trapped in the sediment as the lake withdrew. The degree of mixing varies from spring to spring, which is why salinity runs across a wide range here rather than sitting at one value. William Lynch, in 1847, recorded 84 degrees Fahrenheit and a strong smell of sulphur.

The springs are also moving. Burg, Yechieli and Galili published a study of this complex in the Journal of Hydrology in 2016, describing the springs shifting slightly eastward as the shore retreats and the whole system extending southward without much change in total discharge, with the new seepages varying widely in salinity. The parks authority puts the same thing in plainer terms: the northern springs dry up and new ones break out to the south on ground the lake has vacated, so the balance looks preserved while the habitat is in fact being replaced.

That replacement is the problem. As the lake falls it exposes soft clay laid down on its own bed, and the springs cut down into it, producing what the reserve calls micro-canyons: narrow channels where plants grow only beside the running water, because the salty mud above will not hold them. Standing pools disappear, and the fish that depend on them go with the pools. The parks authority has answered by deepening old pools and digging new ones where water surfaces naturally, and the Times of Israel reported staff moving fish into newly emerging springs.

The vegetation sorts itself into four bands parallel to the shore, keyed to how much water is in the ground and how salty it is. The parks authority lists them west to east: saltbush and sea-blite fed only by runoff off the cliff; tamarisk closer to the springs; common reed and tall sugar cane standing in the flowing water; and rush and glasswort in the saline belt at the eastern edge. The tamarisks explain their own dominance: they push salt out through their leaves, the night dew washes it down, and the ground beneath ends up too salty for competitors.

The fish are the reason parts of the reserve are shut. Tilapia and tooth-carps reached Ein Feshkha through the Jordan and its tributaries and have diverged from their relatives upstream; the dispar tooth-carp, four to six centimetres long, lives in the saline flowing springs and exists only around the Dead Sea. Wikipedia records these saline wetlands as the only known place where blue killifish and Dead Sea killifish live alongside one another, and the pool-digging programme is aimed at keeping them going.

The insects are stranger than the fish. The reserve's own brochure calls Einot Tzukim the northernmost place in the world where the weaver ant Polyrhachis simplex occurs. In winter the workers climb the tamarisks and weave shelters for the cicadas and aphids whose honeydew they live on, using their own larvae as tools: a worker carries a larva and presses it until silk comes out of its upper lip.

Larger animals are a matter of luck. The reserve sits on the migration route between Europe and Africa, and BirdLife International has recognised it as an Important Bird Area for its griffon vultures, Dead Sea sparrows and cinereous buntings. The films in the visitor centre show what the cameras catch and visitors generally do not: wolves, striped hyenas, bats, owls, snakes and the rare swamp cat. The donkeys are not wild; the parks authority brought them in to graze the reeds back.

There is a dig on the flat ground inside the visitors' section, worked twice. Roland de Vaux of the Ecole Biblique, who excavated Qumran three kilometres north, dug here in 1956 and 1958; the parks authority's brochure mentions only 1958. Yizhar Hirschfeld excavated again in 2001 for the Hebrew University. What they uncovered is a farm: a main building of about 24 by 18 metres around a central courtyard, a staircase showing an upper storey, an enclosed yard read as stabling, and an industrial installation with two plastered basins.

The dating has moved. De Vaux placed the traces between 100 and 31 BCE and read the farm as part of the same community that occupied Qumran. Both Jodi Magness and Hirschfeld concluded that the complex is Herodian, meaning after 37 BCE. The end is firmer: the parks authority has the site destroyed in the revolt against Rome of 66 to 70 CE, resettled, then abandoned for good in the Bar Kokhba revolt of 132 to 135 CE. Hirschfeld also found, on the cliff about 50 metres above the spring, a square limestone watchtower with potsherds of the seventh and sixth centuries BCE.

Nobody agrees on what the installation was for. De Vaux suggested a tannery or fish-raising; later readings have offered indigo manufacture, date wine and date honey. Hirschfeld's answer, the one the parks authority's brochure leads with, is balsam perfume: the large round stones crushed the branches, the open pool soaked out the essence, a built cell stored it, the workers used the ritual bath before starting, and the product went out through the port of Gaza. Since the final boiling stage needs ovens and there are none here, Hirschfeld put that step at Qumran, where ovens were found.

The counter-case is printed on the same brochure page: other researchers read the crushing stones and soaking pools as equipment for date wine or date honey, on the grounds that dates were grown here and were a staple. Ehud Netzer went further, publishing a paper in the Israel Exploration Journal in 2005 titled "Did Any Perfume Industry Exist at 'Ein Fashkhah?". A farm stood here and processed something in quantity; what it processed is unresolved.

One more site sits in the reserve, off the visitor circuit. Khirbet Mazin, in Hebrew Metzad Kidron, stands at the southern end on the old shoreline: a fortress tower combined with a dry dock and a boat dock. A 2001 survey nearby turned up a hoard of bronze coins of Alexander Jannaeus, and Hirschfeld read it as a royal dock on a lake that was then a working route between Judaea and Moab.

The archaeology has not been put back up. What is on the ground is a floor plan in low stone: the walls of the villa, the enclosed yard, the two water channels, the reservoir, the plastered basins and the round crushing stones. It sits on the accessible path, so it is one of the easier Roman-period sites in the country to reach, and one of the least dressed up.

The pools are a different case, and it is worth knowing before arriving. Several hold water all year, but this is not simply a set of springs with a fence around it. The parks authority states plainly that over the past decade it has been deepening existing pools and cutting new ones where water emerges naturally, to hold the fish together as the springs migrate south. The deep pool, Tamar, is 1.5 metres deep and opens only when a lifeguard is on duty. What a visitor swims in is a managed habitat, rebuilt about as fast as the lake takes it away.

The newest thing here is the visitor centre. The Times of Israel reported it opening informally at Passover in April 2024 and formally on 21 May 2024, with Environmental Protection Minister Idit Silman at the ribbon-cutting, at a cost of about 35 million shekels. Built to blend into the cliffs behind it, it runs from a hall of oversized models of the reserve's plants and animals, through an auditorium where a geologist, a microbiologist and an ecologist set out the lake's past, present and future, to a room about the reserve after dark. The paper put pre-war visitor numbers at around 170,000 a year.

Two administrative facts are worth carrying. Einot Tzukim lies in the West Bank, and the parks authority files it under its Judea and Samaria district; the status of that territory is disputed, with Israel and most other states taking opposite views. And since 1 January 2026 the operator states on both its Hebrew and English pages that entry is by advance registration only, through its website.

• Ancient and in place: the villa walls, the enclosed yard, the water channels, the reservoir, the plastered basins and the crushing stones
• Not reconstructed: nothing of the farm has been rebuilt above its footings
• Dug by the parks authority in the past decade: deepened pools and new pools cut where springs surface, to hold the fish
• Built in 2024: the visitor centre, at about 35 million shekels, opened formally on 21 May
• Not reachable at all: the Dead Sea shoreline, more than a kilometre away across unstable ground
