A truffle ceremony from Alkmaar is, with Stars Frequencies, a day in Amsterdam. The intercity from Alkmaar to Amsterdam Centraal takes about 38 minutes.
Next group ceremony: Saturday, 19 December 2026, 11:00, Amsterdam.
Intercity trains run from Alkmaar station via Zaandam to Amsterdam. Some continue to Amsterdam Centraal; with others you change to the sprinter at Sloterdijk. Either way it takes about 38 minutes. The stopping sprinter without a change is slower, about an hour.
After the intro call you get the address in Amsterdam, and you can see whether Sloterdijk or Centraal suits you best.
People in Alkmaar often look for something in their own region first. Stars Frequencies holds group ceremonies in Amsterdam, and private ones in Blaricum too. From Alkmaar, Amsterdam is clearly nearest: Blaricum is about an hour by car.
The journey is short enough for a single day. You don't need to stay overnight, and you will be home in the evening.
The ceremony lasts about 7 hours. You are in a group of up to 8 people or on your own with Rosa. She is there throughout the ceremony. At the end you eat together. Don't drive yourself home that day: the train to Alkmaar is the calmest way back.
Letting go is not a condition for taking part. Meditation and sound healing with live singing bowls are fixed parts of every ceremony. They give your mind something to follow while your body gets time to settle.
Rather on your own? A private ceremony can take place on a date you choose, weekdays too. More about the private ceremony
