Looking for a holiday activity the whole family will enjoy? Throughout the summer holidays, you can take part in Operation ABC, a popular nationwide game organized by Déčko, the children's channel of Czech Television.
The competition runs from 27 June to 31 August 2026, and Špindlerův Mlýn is one of the locations where you can complete challenges and collect secret passwords.
How does it work?
Simply choose one of the marked locations, head out on a trip and find the hidden box containing a secret password. Enter the password on the website or in the Summer with Déčko app. Every password you find helps recover the lost letters and automatically enters you into the prize draw.
Where should you go?
Špindlerův Mlýn features one of the official game locations, making it the perfect destination for a pleasant walk or a full-day mountain trip. More information about the exact location is available at the Špindlerův Mlýn Tourist Information Centre or on the official competition website.
After your adventure?
After a fun day with Déčko, relax with us at Resort Špindl. Hotel guests can enjoy unlimited access to the aquapark, our natural swimming lake, wellness facilities and many more summer activities for the whole family.
We wish you lots of fun and good luck in your search for the missing letters!
