Baltic Ice Roads

In a proper winter, Estonia opens public roads across the frozen sea. The longest, from Rohuküla on the mainland to Heltermaa on Hiiumaa, runs around 25 kilometres over the ice - the longest official ice road in Europe - and there are shorter crossings to Vormsi, Kihnu and between the islands. They are real state roads, marked with juniper branches and signs, with rules of their own.

What you actually see

A ploughed white lane running out from the shore until the land disappears, marker posts and brushwood on either side, and other cars far ahead as dots. The experience is closer to crossing a frozen desert than driving a road, and the silence when you stop - which you may not do - is total.

The rules are the memorable part: seatbelts off, doors ready, speeds either under 25 or between 40 and 70 to avoid resonance waves in the ice, big gaps between cars, and no driving in darkness.

When to go

• February to early March - if at all. The ice needs sustained hard frost, and the roads open days or weeks at a time.
• Not every year - recent warm winters have kept them shut entirely; several seasons in a row can pass without an opening.

Honest expectations

You cannot plan a trip around an ice road. They open when the ice allows and close without much notice, and the official channels are the only source worth trusting - social media reports lag reality dangerously.

When they are open, they are safe by design and heavily monitored. Driving onto sea ice anywhere outside a declared road is a different activity with a body count.

Nearby

The Rohuküla crossings start near Haapsalu. If the ice year fails, the ferries run all winter and the islands are the same at the far end.
