Serious Play Rafts on the Rhine

Buy your tickets

When: Thursday, June 18

  • Departure & Return Point:
  • Conference Venue (KUZ
  • Kulturzentrum Mainz)
  • Departure Time: 6:45 pm
  • Return Time: 9:30 pm

During your raft trip, you can relax in the lounge, sunbathe on the sun deck, unwind in a hammock, or dangle your feet in the water from the swimming platform. All this at a leisurely pace, leaving plenty of time to enjoy the Frankfurt skyline and the views of Mainz.

But this is not your typical sightseeing tour — it’s a private evening out with the Serious Play conference crew. A chance to continue conversations beyond the venue, meet speakers and attendees in a relaxed atmosphere, exchange ideas, network, and simply enjoy the river together.

And the best part: you get to steer the raft yourself! No license is required for any of the rafts. For your safety and assistance during the trip, a trained ONWATER tour guide is always on board.

We offer rafts with a capacity of 18 people, as well as smaller rafts for up to 10 people. Choose whichever option fits you best. If you are attending with friends or a partner, feel free to email us days in advance and we will do our best to place you on the same raft.
