If you are in the United States, the chances are high that there is a FlowRider somewhere within a 2-hour drive. There are many all over the world, but definitely spread out geographically and by venue types.
If you go to http://www.flowrider.com/locations/ and click “View All Locations” the entire list of active FlowRider surf simulators will be listed. If you click through to a specific venue page, that venue’s website and contact info should be listed. We don’t own or operate any of these venues, so in order to find out their hours, rates, procedures, please contact the venue directly.
