Estonia's ice roads: when they open and how to plan a winter trip around them

The six crossings, and which ones matter

Estonia's Transport Administration marks and opens official ice roads over frozen sea and lake when conditions allow. The headline is Rohuküla to Heltermaa, 26.5 km from the mainland near Haapsalu to Hiiumaa, the longest official ice road in Europe. Shorter ones link Rohuküla to Sviby on Vormsi, Haapsalu to Noarootsi, and Virtsu to Kuivastu on Muhu — the gateway to Saaremaa. Inland, the Laaksaare to Piirissaar road crosses a narrow arm of Lake Peipus to a village of Old Believers, and a further short Peipus route sometimes serves Piirissaar from the south.

In practice two are worth planning around. The Hiiumaa road is the spectacle: nearly half an hour of driving on sea ice with nothing but marker poles and the horizon. The Piirissaar road is the most likely to open, because a shallow lake arm freezes far more readily than open sea, and it takes you to a place that is otherwise reachable only by boat. Vormsi and Noarootsi are short and mostly local. Virtsu-Kuivastu opens rarely, because heavy ferry traffic keeps a channel broken most winters.

The rule that decides everything: 22 centimetres

An official ice road opens when measured ice thickness reaches at least 22 cm along the whole route, with weight limited to 2.5 tonnes — which means ordinary cars and vans, no motorhomes, no trailers, no minibuses full of people. Inspectors drill test holes repeatedly and reopen or close the road day by day. A road can open on a Tuesday, close on Thursday because of a southwesterly gale pushing water under the sheet, and reopen the following week. Nothing is published far in advance; announcements come days ahead, sometimes hours.

Typical opening dates cluster in February and the first half of March, occasionally late January after a sustained cold spell. Closure usually comes in the second or third week of March. Winters that produce nothing are now common: sustained cold of two to three weeks is needed and several recent winters have not delivered it, particularly on the exposed Hiiumaa route. Assume, when you book, that the ice road is a bonus rather than the plan. Everyone who has ever driven one talks about it for years, which is exactly why people overcommit to it.

How to drive one without frightening yourself

The rules are short, strange and enforced. No seatbelts — so you can get out fast if the ice gives. Keep 250 m between vehicles. Do not stop, do not park, do not turn round outside marked areas. Speed is the odd one: avoid the 25-40 km/h band entirely, because that range resonates with the ice sheet and creates a wave under the car. Drive under 25 or between 40 and 70. Headlights on, daylight hours only — most roads operate roughly 08:00 until dusk, which in February means closing around 17:00.

The surface is not the polished rink people imagine; it is usually snow-covered, grippy and marked by fir branches or reflective poles. Winter tyres are legally required in Estonia from December to March anyway. Do not follow a car in front closely, do not brake hard, and if you hear cracking, that is normal — a sheet at 30 cm makes noise. Fuel up on the mainland: there is a petrol station in Kärdla on Hiiumaa but nothing on the crossing itself, and no phone signal in the middle for parts of the Peipus route.

If they do not open: the ferry plan

Every one of these destinations has a year-round ferry. Rohuküla to Heltermaa runs to Hiiumaa in about 75-80 minutes with several sailings a day; Virtsu to Kuivastu reaches Muhu and onward Saaremaa in around 27 minutes with departures roughly hourly. Winter timetables are thinner than summer ones but still workable. A car plus driver costs in the region of €10-15 with foot passengers a few euro each, and in February you can generally board without a reservation — unlike the summer, when advance booking is essential and the sailings sell out.

Ice does complicate ferries. In a hard freeze the crossings run late as vessels push through pack ice, and delays of 30-60 minutes are normal; in extreme conditions sailings are cancelled and the islands rely on the ice road or aircraft. There is a small plane service between Tallinn and both Kärdla and Kuressaare, useful as a fallback, subsidised and cheap by air standards but with tiny capacity. Plan islands in winter with a day of slack either side and do not book a same-day international flight out of Tallinn on your return leg.

Hiiumaa in ice-road week: what it costs

Kärdla, Hiiumaa's small capital, has a handful of hotels and guesthouses with winter doubles around €55-85, and there are farm stays and rented cottages across the island from €50. Winter demand is low enough that a week's notice is usually plenty, though when the ice road opens Estonian day-trippers appear en masse and the better places in Kärdla can fill on a Saturday. What you will not find is much open food: expect a couple of restaurants running in Kärdla, the harbour and lighthouse cafés shut until May, and shops closing by 20:00.

The island in winter is about emptiness — the Kõpu and Tahkuna lighthouses in flat grey light, kilometres of empty juniper heath, sea ice heaped along the shore at Ristna. Give it two nights. If the ice road is open in both directions during your stay, take it once and take the ferry once; the crossing is memorable but 26.5 km at 60 km/h in whiteout light is also monotonous, and the ferry offers a hot coffee and a deck. Note that ice roads are free while ferries are not, which is a small budget bonus.

Lake Peipus and Piirissaar: the other kind of ice

The Laaksaare to Piirissaar road, some 8-9 km across a shallow arm of Lake Peipus, is the one with the best odds in a modest winter. Piirissaar is a low, flat island of Old Believer villages, wooden houses, an onion-growing tradition and fewer than a hundred permanent residents. Visiting in winter is an odd, quiet privilege: no cafés, no shop worth the name, no accommodation unless arranged privately in advance. Treat it as a half-day drive out and back from a base on the mainland shore, taking your own food and a full tank.

Base yourself along the Onion Route on the western lakeshore — Kolkja, Varnja and Kasepää — where guesthouses run €50-75 in winter and one or two of the fish-and-onion restaurants stay open with reduced hours; ring ahead rather than turning up. Tartu, 50-60 km away, is the safer base with full winter life and doubles at €60-95. Peipus itself in February is a landscape event: ice fishermen's huts scattered to the horizon, quad bikes on the lake, and a sunset over a frozen sea-sized surface that photographs better than anything on the coast.

Building a trip that works either way

The tactic that never fails: plan a mainland winter route through Haapsalu, Matsalu and the Läänemaa coast, all of it good in February — the promenade and castle ruins at Haapsalu, the frozen reed beds at Matsalu, the empty beach at Puise — with the ice road as an option you can take on 24 hours' notice. Haapsalu doubles run €55-90 in winter and the town has enough open restaurants to eat well. From there Rohuküla is 10 minutes by car, so you can decide over breakfast whether it is an ice day or a ferry day.

Do not build the trip the other way round, arriving with a non-refundable island booking and hoping. And do not attempt an unofficial crossing on a whim: driving on ice outside a marked and opened road is both illegal and how cars end up on the lake bed. Check the Transport Administration's ice road page and local news the morning you travel, note the closing time, keep 250 metres, and leave the seatbelt off. That last instruction is the one visitors find hardest and the one that matters most.
