British Canoeing, the national governing body of our sport has a wealth of online resources online to help you to find places to paddle. The law surrounding access can vary greatly so we would encourage you to check with your own home nation (British Canoeing for England, Canoe Wales, Canoe Scotland, and Canoe Northern Ireland)
The Go Paddling Website covers all home nations and features some excellent resources to help you get the most out of your time on the water.
Paddle Points is another one well worth visting, this interactive map allows you to find places to get on the water all accross the UK, often with helpfull notes including where to get on and off the water, ease of access etc.
If you’re really enjoying yourself we’d encourage you to find and join your local club.
