The hike towards the Laguna de los Tres is doubtless one of the loveliest in these parts, allowing you to get up close and personal with the impressive granite peaks of Fitz Roy. It will be quite hard work, but rest assured, your efforts will be rewarded by several admirable viewpoints. Nevertheless, if this seems an overly ambitious objective to you, there is a variant that avoids the steepest part at the start of the trail.
