The event promises two-days of mostly free entertainment for the whole family in Kidwells Park and the town centre.
Attractions include a packed programme of music from local bands performing on a main stage and acoustic stage culminating in a Saturday, evening concert headlined by Rat Pack and Abba tribute acts followed by a spectacular fireworks display.
The park will also offer a host of pirate-themed stalls, sideshows and games, many run by community groups, organisations and charities.
There will also be refreshments for every taste, a funfair, and an artificial beach – ideal for hiding buried treasure.
In keeping with the pirate theme there will be a treasure hunt taking participants to shops throughout the town centre in search of clues.
Also taking place in the park on Saturday will be a strongman competition and a display of extreme mountain bike skills.
The Magnet Leisure Centre will be holding a fun zone for younger festival-goers and there will also be story-tellers and face-painters.
The programme of music continues throughout the Sunday with the festival being brought to a close by the Maidenhead Concert Band.
The Advertiser will be at the festival on both days, so please drop in at our stand for a free balloon and to take a pirate selfie against our special backdrop. We aim to put the pictures on social media and on our website.
While the festival kicks off properly from 10am on Saturday, the funfair will be open from 2-8pm tomorrow in advance of the main event.
Festival chairman Steph James said: “We have a fantastic event planned with something for all the family. And, with most of the entertainment free, it offers a great weekend for everyone.
“So please do take advantage of all the hard work that has gone into preparing this year’s festival.
“Come along and enjoy yourselves, support the festival, the town and the many charities taking part, in particular the Alexander Devine Children’s Hospice Service, which is this year’s chosen charity for the festival.”
