Rising above the harbour, this Ferris wheel offers a fantastic panorama over central Helsinki from a height of up to 40m during the 10-minute 'flight'. A truly unique experience is the SkySauna gondola, allowing you to sauna and sightsee simultaneously: one hour (up to four people €240 to €320) includes towels, drinks and use of a ground-level Jacuzzi and lounge.

Alternatively, for €195 you can ride in the VIP gondola, with glass floors below, leather seats and a bottle of champagne.
