Okay
Logistics: You will need to either fly and rent or ferry and drive
Rosslare is better than Dublin as the irish roads are just better than trying to cross Wales
Cost of ferry was 216 for me and the car and around 270 if I had more people
Hostel in Cardiff the YHA was five minute drive from the course and was a hotel with bunk beds was 423 for a 4 person room for three nights, really nice hostel.
The course itself needs around 8 cumecs to make it challenging and it has playspots on it. it's around 500m and you can do it in around two minutes if you want
It's £10 plus £5 membership the first time to paddle the entire day there.
Issues might be lack of pump times during the winter months
Overall wish we had one of these in Ireland
It's an easy one to organise and run and it's really good fun
