The River Tweed is the most famous of the Borders rivers, and the longest. It is a particularly good place for canoeing and kayaking.
Generally, the river is simply a largish flatwater river with moderate flow and a small number of grade I rapids. However, there are a number of characteristic "caulds", which are large weirs. Some of these are troublesome and can be Grade 3.
There are also a few rapids, the most famous, and difficult, of these is the series of drops at Makerstoun which are normally Grade 3.
The Tweed is one of the country's biggest fishing rivers, so please be aware of and respectful to the reasonable needs of any anglers you meet when you are canoeing.
The Tweed is not particularly developed for canoe touring, with few facilities, and campsites being awkwardly placed for the river. Despite this, wild camping is not encouraged, so discretion and an "invisible"/no trace approach are needed if doing so. 3-4 days would be a typical duration for the river below Peebles. Above there water levels often make canoeing a loaded open or kayak difficult.
