Colossalcon is the date many of the top cosplayers across the country circle on their calendars each year in anticipation of the biggest cosplay pool party. Held each June at the Kalahari Resort and Waterpark in Sandusky, Ohio, Colossalcon gathers about 20,000 attendees across four days to celebrate cosplay in a waterpark environment.
This usually means cosplays of all kinds are adapted for swimsuit friendly wear and pool partying. In addition to waterpark fun, the resort also contains a petting zoo with a variety of wildlife as well as nearby fields and forested areas for unique cosplay photoshoot opportunities. With tropical-themed indoor and outdoor swimming pools and slides, and some beautiful surrounding countryside, cosplayers and photographers can get a little crazier than usual.
Sandusky, Ohio may not be the first thought to come to mind when it comes to amazing cosplay conventions, but every year many of the best cosplayers make the pilgrimage to Colossalcon for one of the biggest cosplay conventions of the year.
