The small wooden boats are quaint, sturdy, and have plastic flaps that can be pulled down if it is raining. The sun came out just enough to have an enjoyable hour on the water. Tour lasts about an hour and costs 18 euros. The staff was nice and friendly. The commentary provided was a recording in English - worked just fine for me, I learned some things about Riga. You spend most of the time in the canal, and then head out to the river to make a complete circle around.
