After lunch, we headed about 30km to Lake Bohinj. It was just as beautiful, but considerably less crowded. We (I) grabbed an ice cream before walking a little ways around the lake. There was a nice little paths that led down to the lake, where we sat for a while enjoying the cool water and (I) scared the school of fish with our (my) shadow.
Sitting there, we saw a woman taking a kayak lesson on the lake. After a bit, they dropped under the bridge down the river. We hemmed and hawed about it, but eventually decided to ask about the lessons. As luck would have it, there was only one session open all of the next week--the next day at 3 in the afternoon.
