When

When can you see Sort Sol?

Timing is everything. Be in the right place at the right time, and chances are high — but the starlings decide.

Forår og efterår

The starlings gather during migration: from mid-March to mid-April, and again from mid-August to late October. Autumn sees the largest flocks.

The last hour before dark

The phenomenon occurs at dusk, typically 20–40 minutes before darkness, as the flocks gather over the reed beds to roost. Arrive well before sunset.

Calm and dry weather

Sort Sol is a natural phenomenon — no one can guarantee it. Calm, clear evenings provide the best dances. Bring warm clothes, rubber boots, and binoculars.

Where

The best places to experience Sort Sol

The starlings roost in the reed beds along Vadehavet and in Tøndermarsken. Here are the five best spots to see them — all with nearby parking.
