The drop-out rate for teenage girls participating in sports continues to be of "significant concern" to Sport Ireland.
It found around 30% fewer girls are involved in sports at secondary school level than in primary school.
Recent research published by the sporting body found that while girls and boys have similar sports participation levels at primary school (girls 94%, boys 89%), almost one-third fewer girls take physical exercise at post-primary level (girls 65%, boys 79%).
Boys are also more likely to meet the national physical activity guidelines than girls.
Sport Ireland's Women-in-Sport lead and former Ireland Rugby International Nora Stapleton said the reasons for the drop-off in teenage girls are complex.
She said: "There are challenges. Girls would tell us schoolwork, for example, responsibilities at home, all these things can play a factor in drop-out, body image, lack of confidence that comes with puberty is well documented, as well."
The sporting body recently launched the "HERMOVES" campaign.
Ms Stapleton said: "The idea of the campaign is to inspire and motivate girls to try new activities and to see more sports, to make more sports visible to them, because, a lot of the time they have one certain view of 'sport', but we want to show them than sport can be so many different activities.
"It can be orienteering, archery, hiking, mountain climbing, BMXing, running, football, whatever, and we want to open their eyes to more opportunities."
One of the ways this is being done is through taster programmes like the Surf Camp for Girls being run by the Cork Sports Partnership with the Inchadoney Surf Club in west Cork.
Cork Sports Partnership Co-ordinator Kristine Meenaghan said the four-week programme is being run as part of the dormant account "Girls Get Active" fund received through Sport Ireland.
Ms Meenaghan said the focus for the local sports partnerships is to encourage, promote and provide environments to allow people who are inactive, or who would like to take up a sport of physical activity for reasons other than competition, to make that happen.
For those taking part in the surf camp, today was great fun.
Chantal Porcelli, 14, said she would recommend surfing to other girls.
For her, the best part was getting up on her board and catching a wave while 15-year-old Suhana Sheehy said she enjoyed the freedom of being out on the waves.
Thirteen-year-old Meabh Lyons said it was a bit windy out on the water today, but she really enjoyed it while 12-year-old Eileen Murphy said the course was "awesome".
She said her mother signed her up for it and she was having loads of fun.
Leah Hickey, 13, who also likes to swim, said she really enjoys trying a new sport.
She believes many girls her age give up sports because they become so competitive.
Leah added the secret for her is that it has to be fun and today was certainly lots of fun.
