Where to stay

Participants typically stay in the Ouchy district of Lausanne, near the waterfront. Options range from historic 5-star grand hotels with direct lake access to business-focused boutique hotels that host international sports delegations. Prices typically range from 250 to 500 CHF per night depending on the luxury tier and proximity to the race start. Some entries allow for independent arrangements, such as camping sites located along the northern lakeshore, which offer a more modest, nature-focused stay.

Things to do nearby

The region offers extensive leisure activities for the race weekend. Swimmers can explore the UNESCO-listed Lavaux terraced vineyards via local hiking trails, visit the Olympic Museum in Lausanne, or take the CGN ferries across to the thermal town of Évian-les-Bains. Kayaking and SUP are readily available in the calmer bays, and the proximity to the Alps provides a cooling retreat for those extending their stay beyond the event.
