Gardai deployed increased resources, including plain clothes officers, to clamp down on anti-social behaviour in the seaside town.
Up to €11,000 worth of drugs, the majority of which was cocaine, were seized by gardai across the weekend.
The 29 people were arrested for incidents of public order, possession of drugs and drink/drug driving.

Superintendent Brendan Fogarty from Bandon Garda Station said: "We had well over 20,000 people come through Kinsale over the bank holiday weekend, the vast majority were respectful and complied with Gardaí and stewards.
"However, we had 60 detections for possession of suspected drugs, mostly cocaine, which amounted to approximately €11,000.
"This is an alarming amount of detections for drugs. Drugs have such a negative impact on so many lives and have no place in our communities.

"Six people also took the risk of getting behind the wheel with drugs or alcohol in their system.
"People who do this are putting themselves, our family, and our friends at risk by driving whilst intoxicated.
"If you are going out and want to have a few drinks, leave the car at home. Never ever drink and drive.”
