Bubble Planet immersive experience in Cologne

For a family or rainy-day Cologne trip from the Netherlands, plan Bubble Planet from EUR 12.40. It runs from 14 July to 1 November.

• More than 12 themed rooms link bubbles, light, imagined landscapes and interactive installations into a route you walk through.
• VR, optical illusions and a hot-air-balloon flight simulator turn a familiar childhood object into a journey you enter.
• Check the slot, duration and child rules before booking; under-12s need an adult, and socks are needed for the bubble pool.

Hokimi field note: Make it the indoor anchor of a Cologne day, then add a riverside walk or dinner around it.
