  • By bus : Take the “V” bus at the Geneva station (Cornavin) and get out at Ecogia.
  • By taxi : ~ CHF 45.-
  • By car : Take the lake road direction Lausanne for 15km. In the middle of Versoix (at the lights) turn on the left direction Ecogia.

From the Geneva airport

  • By train : Train every 15 min. for the main station (Geneve-Cornavin). Change there and see above.
  • By taxi : ~ CHF 45.-
  • By car : Take the highway direction Lausanne, get out at the first exit “Bellevue/Versoix”, follow the lake way direction Versoix (5 km). In the middle of Versoix (at the lights) turn on the left direction Ecogia.
