Fortunately, most visitors return to the parking lot after visiting the Seljalandfoss. However, if one continues west less than half a mile, one encounters the Gljúfrabúi. This waterfall begins high and then disappears into a narrow cleft. It is aptly named, translated as “Dweller in the Gorge.” It falls into a slot canyon, so the its bottom is visible only if you enter a narrow crack, wading through shallow water into a mossy cylindrical chamber.
I had not planned to enter because, despite going behind Seljalandsfoss, my shoes were fairly dry. However, Michael and Sara came out with gorgeous pictures, so I cast aside my fastidiousness over wet shoes. Actually Michael advised me just to balance on the wet rocks and anchor my hand on the side wall. Ha, my balance is still good, but not that good.
As you can see, the trip inside was well worthwhile.
