Hello Sylvia, 
I am happy to hear you will visit us this summer with your daughters!☘️
Being submerged in the Irish culture will be a great way for them to perfect their English while meeting new people. 
Bundoran is definitely the place to surf, there are several 
schools to go to, including the 
Bundoran Surf Co.  🌊
There is also an 
Equestrian Centre in Donegal where they will be able to have amazing rides in nature. 🐎
Since you will be here during the summer, it will be a perfect opportunity for them to be part of the 
local summer camps and practice their English while also having lots of fun activities. 
Also, you can try the 
local English school that offers many activities like surfing, horse riding, and multi-adventure, which includes everything that you are looking for. 
Hopefully, this will come in handy for you and you have the best summer so far. 
Best wishes, 
Vivian
