<div id="c3be0912bb716eee4ca644c1dfc4ecde4"></div>Tampa's annual River O'Green Fest returns this year on March 15, 2025! The name says it all—you can watch the river turn a bright shade of green in celebration of the St. Patrick's Day holiday. This is done using environmentally safe dyes, non-toxic and biodegradable dyes that meet the National Sanitation Foundation Standard 60 certification for use in and around drinking water.
River O'Green Fest has been celebrated in Tampa since 2012 and it's been among the best things to do for St. Patrick's Day in Tampa ever since.
“Seeing our Hillsborough River turn emerald green in celebration of St. Patrick’s Day is a great reminder of the excitement and fun that Tampa has to offer,” added Mayor Jane Castor. “I know how much I look forward to this annual tradition and the opportunity it brings to come together and celebrate all that makes our city great.”
