From the village of Okrokana, cross the bridge to begin the hike. Head left up the hillside and follow the unsurfaced road along the river. The river curves around to the left with extraordinary rocky cliffs on the opposite side. You will then cross a bridge over a stream before crossing over the river itself, after which the Truso Valley widens and impressive snow-capped peaks come into view on all sides.
When you reach the small footbridge crossing the river to a small campsite cross that and continue up the side of the hill and walk along the ridge before descending to the famous Abano Mineral Lake. Don’t be cheated it’s not really a lake, a large pond at best. But it’s a gorgeous geological wonder, where carbon dioxide bubbles gently rise from the depth and the clear, lifeless water flows down into the river below.
Continue along this side of the river (you may find yourself having to navigate your way through some bogs and lots of curious cows in early summer) until you reach the village of Ketrisi, with its notably pristine watchtower and dozens of collapsing houses which most of them abandoned these days. Beyond Ketrisi you’ll continue along the middle of the valley and pass two monasteries (one for monks, one for nuns) and a few truly remote houses. As you approach the end of the valley, you’ll see your end point at the top of a hillside to your right.
