Green Ljubljana: parks, gardens and easy escapes

Ljubljana wears its greenery like a manifesto. The old town was closed to motor traffic in 2007 and the pedestrian zone has been widening ever since; the river banks double as promenades; and the European Green Capital title the European Commission awarded the city for 2016 still describes daily life rather than a single year of it. Better yet for the visitor: almost all of it begins within a ten-minute walk of the Triple Bridge.

That proximity is the whole argument of this piece. In most European capitals a green day out means a train, a timetable and a packed lunch. In Ljubljana it means walking west for a quarter of an hour until the buildings stop and the forest starts, then walking back in time for dinner. You will not need a car. You will barely need a bus.

Key facts

• The big park: Tivoli, spreading from the city's western edge into wooded hills, part of a protected landscape park of some 459 hectares since 1984
• Oldest garden: the University Botanic Gardens have been growing since 1810; the outdoor garden is typically free for individual visitors
• Viewpoint climb: Castle Hill's shaded trails on foot, or the funicular for the effortless version - expect to pay around EUR 6 for an adult return
• Signature walk: the Path of Remembrance, a tree-lined ring of roughly 33 kilometres tracing the city's wartime perimeter
• Time needed: two unhurried days for the green spine of the city, a third for a summit or a marsh beyond it

Two days, and the order to walk them in

Sequence matters more than usual here, because Ljubljana's green spaces sit on two sides of the centre - river to the south and east, forest to the west - and crossing between them repeatedly wastes an hour you could be spending under trees.

Morning one, the river. Start at the Triple Bridge and walk upstream, away from the packed terraces, into Krakovo: a grid of market gardens that has supplied the city's stalls for generations and still looks like allotments dropped into the middle of a capital. Carry on into Trnovo for Plecnik's Trnovo Bridge, which the architect treated as a square rather than a crossing - wide, planted with birches, flanked by stone pyramids. Then the Botanic Gardens, and over the footbridge across the Gruber Canal to Spica, the point where the Ljubljanica widens below the Old Town. Allow two to three hours at a genuine amble.

Afternoon one, Castle Hill. Up on foot, down by whichever path tempts you. An hour and a half including time at the top.

Morning two, Tivoli and Roznik. The big one: half a day, longer if you eat up there.

Afternoon two, Koseze Pond or a stretch of the ring. Both are flat, and both are where Ljubljana goes rather than where it sends visitors.

If you have only one day, cut the river walk down to Spica and back, and spend the saved time on Roznik. The hill is what people remember.

Tivoli: the park, the promenade, the mansions

Tivoli is Ljubljana's green lung, minutes west of the centre, and it is far bigger than first impressions suggest. The protected landscape park it belongs to takes in the formal park plus the forested rises of Roznik, Sisenski hrib and Koseski borst; the Slovenian nature-parks network describes it as the most visited landscape park in the country, with something close to two million visits a year.

Its formal heart is the Jakopic Promenade, the broad chestnut-lined avenue laid out between the wars by Joze Plecnik - the architect whose bridges, markets and river walls shaped the whole city - and named for the Impressionist painter Rihard Jakopic. It now works as an open-air photography gallery: large-format prints mounted the length of the avenue, changed several times a year, free to walk past at any hour. It is the rare public art venue that cannot be closed, sold out or rained off, and locals cut through it without breaking stride.

Two mansions sit in the park and are worth knowing about even if you do not go in. Tivoli Mansion houses the International Centre of Graphic Arts, which has made printmaking an unlikely local speciality. Cekin Mansion, a late-Baroque pavilion on the park's city edge, holds the national museum of contemporary history and its permanent account of the Slovene twentieth century - trench, occupation, socialist Yugoslavia, independence. It is where to go in the park if the weather turns, and it is a five-minute walk from the lawns.

The one to seek out is Svicarija, deeper in. A wooden inn stood here from the 1830s; the present building went up in 1908 as the Hotel Tivoli, became a warren of sculptors' studios after the Second World War, and reopened in 2017 as an artists' residency and exhibition house run by the graphic arts centre. There is a cafe. Sitting on its terrace with a coffee while somebody carries a canvas past you is about as Ljubljana as an afternoon gets.

Beyond the lawns, the fountains and the long reflecting pond, the park simply dissolves into woodland. There is no fence, no gate, no moment at which you are told you have left the park. That is the trick of the place.

Up Roznik, the locals' hill

Keep walking through Tivoli and the paths begin to climb Roznik, a wooded hill of a little under 400 metres where Ljubljanans take their daily constitutional. The gradient is gentle, the surface is forest track rather than rock, and the canopy means it stays walkable in high summer when the riverside is baking.

The summit is called Cankarjev vrh, Cankar's peak, after Ivan Cankar, the writer who lived up here between 1910 and 1917. There is a memorial room in one of the adjoining buildings, and above it the small Church of the Visitation of the Blessed Virgin Mary, usually locked but worth the last few steps for the view: on a clear day the Kamnik Alps float above the rooftops.

And there is the inn. Gostilna Roznik sits just below the church with a garden under the trees, serves Slovene home cooking of the roast-and-dumplings school, and opens daily - though it closes in genuinely bad weather, so a wet Tuesday is not the day to count on lunch at the top. Expect to pay roughly what a solid main course costs elsewhere in the city, which is to say noticeably less than the equivalent terrace down on the Ljubljanica.

At the foot of the hill, on the Tivoli side, Gostilna Cad has been feeding walkers since a master baker of that name opened a wine tavern here in 1889. It grills and spit-roasts, and it is the better bet in the evening or in poor weather, being attached to a small hotel and not dependent on its garden.

Allow an easy hour round trip from the Jakopic Promenade if you go straight up and straight down, two to three if you stop to eat. Sturdy trainers are enough in summer; after rain the clay underfoot turns slick and boots earn their keep.

Castle Hill on foot

Everyone rides the funicular to Ljubljana Castle. Fewer take the wooded trails that spiral up Castle Hill from the Old Town, which is strange, because they are shaded, short, and the reason the hill is green at all.

Go up on foot - fifteen to twenty minutes from the market side, steeper from the south - and come down whichever way tempts you. You will have had a forest walk in the geographic centre of a capital city. If the climb does not appeal, the funicular takes about a minute and, at the time of writing, costs roughly EUR 3.30 one way or around EUR 6 return for an adult, with reduced fares of about EUR 2.30 and EUR 4.50 for children, students and pensioners, and a family return of around EUR 15.

A useful compromise: ride up, walk down. The descent is the better direction for the trees anyway, and it delivers you back into the Old Town rather than at a ticket barrier. The castle's exhibitions and viewing tower are a separate matter - a combined castle-and-funicular ticket runs to around EUR 19 at the time of writing - and are entirely skippable if trees rather than history brought you here.

The river: Krakovo, Trnovo, the gardens and Spica

South of the Old Town the Ljubljanica loses its crowds within about four hundred metres, and the walk sketched above becomes one of the quietest hours in the city.

The University Botanic Gardens have been cultivating since 1810, which makes them, by the garden's own account, the oldest continuously operating scientific institution in the country. Two hectares hold something over 4,500 plant taxa, with native Slovene flora as the founding collection - the point of the place, and more interesting than it sounds once you realise how much of it grows within two hours of here. The outdoor garden is typically free for individual visitors and generally opens early, from around half past seven, closing somewhere between late afternoon in winter and early evening in high summer. The tropical glasshouse is a separate, modest ticket of about EUR 4.50 for an adult and roughly EUR 3.50 for students, and usually opens around mid-morning. Both the hours and the fees shift with the season, so check current arrangements before making a special trip.

From the gardens a footbridge crosses the Gruber Canal - an eighteenth-century flood-relief channel that is a handsome piece of engineering in its own right - and lands you at Spica, a riverside park on a spit of land where the water broadens. Grass, wide paths, a cafe in season, rowers going past, and none of the pressure of the centre. It is where students come to do nothing, and doing nothing there for forty minutes is a legitimate use of a holiday.

The Path of Remembrance: a ring, not a park

To our mind the most moving green space in Ljubljana is a line. The Path of Remembrance and Comradeship - Pot spominov in tovaristva, signed PST, and known to locals as the path along the wire - is a gravel walkway of roughly 33 kilometres, about four metres wide and lined with several thousand trees, tracing the barbed-wire fence with which occupying forces encircled the city during the Second World War.

The full circuit takes around eight hours on foot with barely any climbing, which makes it a long day rather than a hard one. Almost nobody on a short visit should attempt all of it. What you should do is walk or cycle a segment: our pick is the stretch running from Koseze Pond around the back of the Tivoli hills towards the zoo, wooded, almost entirely flat, and under an hour at a walking pace. City bus routes cross the ring at many points, so you can join where you like and leave when you have had enough.

Locals jog and cycle it daily without ceremony, and that is part of the effect - a memorial absorbed into ordinary life rather than fenced off from it. Once a year, usually on the first Saturday after 9 May, the city holds an organised mass walk along it, a tradition running since the 1950s and one of the few occasions on which a European capital voluntarily spends a Saturday walking its own former perimeter.

Koseze Pond and the north-western edge

Koseze Pond, on the north-western edge of the landscape park in the Siska district, is where you see Ljubljana off duty. An artificial pond with a path around it, benches, wooden viewing piers and an outdoor gym, it takes about a quarter of an hour to circle and considerably longer to leave. Herons, families, teenagers, dog walkers, and the PST running along the top of it.

From here, trails lead into Mostec and up the back of Roznik, which means you can arrive by bus, circle the pond, walk over the hill and come down into Tivoli - a genuine cross-city forest traverse ending at a coffee. It is the walk most visitors never hear about, and the one to choose if you have a spare half-day and no wish to see another church.

The zoo sits on the southern flank of the same forest and is a reasonable option with children, though the hill behind it is free.

Easy escapes: a summit, a marsh, a garden

Smarna Gora, at 669 metres, is the hill Ljubljana climbs at weekends. City bus number eight runs out to Tacen on the northern edge of town; from the bridge stop, the standard route takes roughly forty minutes to an hour of steady walking, and there is a mountain inn at the top serving the sort of food that assumes you have earned it. Go early on a Sunday and you will meet half the city coming down. Round trip from the centre: about half a day.

The Ljubljana Marshes south of the city are the opposite experience - flat, wet, quiet, full of birds, and layered with the archaeology of prehistoric pile dwellings. They are best reached by bicycle along the lanes running south towards Ig, an hour or so each way on a mixture of asphalt and gravel with very little traffic. Bring binoculars and low expectations of drama; the reward is space, which central Europe rarely gives away for nothing.

Volcji Potok Arboretum, out towards Kamnik, is the seasonal wildcard. Its spring show - the arboretum counts its tulips in the millions - peaks in April and is worth reorganising a trip around. Regional buses towards Kamnik take somewhere around forty minutes and stop at or near the entrance, though services to the gate itself are infrequent, so check the timetable before committing. There is an entrance fee, higher during the flower show, and the grounds typically open early and close around dusk.

When it works, and when it does not

Late April to early June is our pick. The Botanic Gardens and the arboretum are at their peak, the forest is in new leaf, and the terraces have opened without the July crowds.

September and early October run it close, with warm days, harvest menus and the warmest light of the year on the castle hill. October is also the wettest month, so carry a jacket rather than a plan.

July and August are hot and busy, and the riverside becomes a scrum. This is precisely when the green city pays off: Roznik and Castle Hill are shaded and several degrees more civilised than the promenade, and the locals have gone up there for exactly that reason.

November to February is the honest caveat. Ljubljana sits beside marshland in a basin and averages on the order of sixty foggy days a year, most of them in late autumn and winter. That fog can settle for days, and it will flatten every view mentioned here. It also does something unrepeatable to the bare avenue of the Jakopic Promenade, so it is not a reason to stay away - only a reason not to build the trip around a panorama.

What to skip

Skip the organised city walking tours if green space is your interest. Everything here is self-guiding and signposted, and the interesting decisions are about which path to take, not which fact to hear next.

Skip the castle's paid interiors unless the weather has defeated you.

Skip hiring a car. Every place named here except the arboretum and the marshes is reachable on foot or by a city bus, and the marshes are better by bicycle anyway.

And skip any attempt to complete the ring. The Path of Remembrance is not a challenge to be finished on a three-day visit; it is a thing to step onto, walk for forty minutes, and think about.

Tip: The city's bike-share scheme is among the cheapest ways to link all of this - a week's subscription typically costs around EUR 1, and journeys under an hour are usually free provided you dock the bike and pause a few minutes before taking another. Registration needs a card and authorises a sizeable hold against loss or damage, so do it at the hotel rather than at a terminal in the rain. Inside the pedestrian zone there are also small free electric buggies, the Kavalirji, which run most of the day and will carry you across the old town when legs have failed.
