Hoornse Vaart swimming pool hides free tickets in Alkmaar for five days

Published on: 30 July 2026

Swimming pool Hoornse Vaart is closing out the summer holidays with a cheerful treasure hunt in the city centre of Alkmaar. From Monday 10th to Friday 14th August, a striking envelope will be hidden every day. Each envelope contains four complimentary tickets for the swimming pool. Via Facebook and Instagram, swimming pool Hoornse Vaart will share a vague photo and a clue every day. Whoever finds the envelope first gets to keep the complimentary tickets. The first clue will appear on Monday 10th August.

Five days, five envelopes

The envelope is easily recognisable. On the front, ‘Gefeliciteerd!’ is written in large letters and a photo of the Hoornse Vaart swimming pool can be seen. Each envelope contains four complimentary tickets. With these, the finder can come swimming together with three others.

“With this promotion, we want to bring the summer holidays to a close in a fun and surprising way,” says Marcel Ruitenberg, location manager of the Hoornse Vaart swimming pool. “We are curious to see how quickly the envelopes are found. Four complimentary tickets are waiting for the lucky finders to come and enjoy a swim together. Because a magnificent new swimming and sports complex is being built, this is the outdoor pool's final summer season in its current form. An extra special reason to fully enjoy the outdoor pool one last time over the coming weeks.”

A new clue every day

The envelopes will be hidden in the vicinity of well-known spots in the centre of Alkmaar. Think, for example, of the Grote Kerk, the Laat or the Huis met de Kogel. Where the envelope is located on that exact day remains a secret, of course.

Every day, swimming pool Hoornse Vaart shares a clue and a vague photo showing part of the surroundings via Instagram and Facebook. It is then up to the participants to recognise the location and be the first to find the envelope.

Joining the search operation

The first clue will appear on Monday 10th August. After that, a new envelope will be hidden every day up to and including Friday 14th August.
