Summer 2023 Events

Dark colored banner for the Meteor Shower Cruise. There are stars in the background with a Lake Geneva Cruise Line boat along the bottom. The text in the top right reads "What? Join Lake Geneva Cruise Line and GLAS Education on an evening cruise for the Perseid Meteor Shower! When? August 9th and 13th, 2023 from 9-11pm. Where? Riviera Docks 812 Wrigley Dr., Lake Geneva, WI 53147"

Take to the waters of Geneva Lake to enjoy a unique Perseid Meteor Shower experience. The Lake Geneva Cruise Line and GLAS Education are partnering to offer you a lovely summer Starlight Evening Cruise for this annual celestial event. Make a wish as you admire the meteors (popularly known as “falling stars”), learn from our Tour Guides about the constellations and their rich cultural heritage through engaging and interactive activities, and gaze up at the glimmering night sky over Geneva Lake as you glide along the waters in the comfort of the Cruise Line’s beautiful boats.

The Perseid Meteor Shower is an annual event caused by the Earth’s orbit passing through the debris stream from Comet Swift-Tuttle. This dust and dirt from the comet burning up in the atmosphere brings us a spectacular show of “falling stars” every August!

As with any stargazing event, the weather is very important and unpredictable. Cancellations will only occur in the case of heavy rain or stormy weather.
