The action starts on Friday 1 August with the three-day Rock the River event.
This is the second time live music and wakeboarding have been combined in Conwy and organiser Andy Jones hopes it'll be just as much of a success.
"Last year it was sold out," said Andy. "It brought in a different demographic of people to the town, too. All of Conwy's traders said it's the best weekend's trading they've ever had and they're very much behind us."
Rock the River was the idea of four friends who liked to wakeboard and wanted to combine it with a party atmosphere in their home town.
This year, they've invited local bands James Cassidy and The Screaming Citizens to play with others in a marquee at the newly-extended end of the quay.
Meanwhile, a rail will be set up in the waters just off the quay for the 12 pro-wakeboarders to do their tricks.
Saturday is also Conwy Quay Day and the first day of racing in the Conwy River Festival.
"It's been going for 17 years," said festival chairman and harbourmaster, Tony Mead.
"We began by just inviting a group of historic boats to come here for a sailing race. Now it's essentially a nine-day regatta."
With over 150 entrants and races every day, Tony says this regatta is aimed at those who enjoy sailing, but aren't necessarily keen racers.
"We're not aimed at racing experts, but people with boats who want some fun," he said.
"We have a special Corinthians class for those who really don't want to race aggressively; it's more of a rally, and everyone's got a trophy by the end of the regatta."
Some of the vessels taking part date back to the 19th century. A sailor on a 100-year old yacht himself, Tony is well used to how they handle.
"They have their own challenges; you need more manpower as they're more work-intensive. Because they've got larger sails for their size, everything's a lot heavier. But they go just as fast."
There will also be entertainment quay-side.
"We'll have male voice choirs, clowns, torchlight parades, wandering jazz bands and a rowing regatta," said Tony.
"The rowing competitions have gone on for hundreds of years between the local fishermen who still participate in ours - and usually win!"
