A shorter introduction
A half-day itinerary concentrates the visit into a shorter window. It can work well when you want a first look at the gorge and time for a slower afternoon. It still needs a clear terrain description. Short does not mean flat or effortless.
Ask which waterfalls are included and how much of the outing is walking, resting or getting to the start. Leave time for the return climb and the journey back to your accommodation.
A longer day outdoors
A full-day hike usually means a greater commitment of time and energy. More time in the gorge can offer a different rhythm, but the actual sections and stops still depend on the itinerary and conditions.
Choose it because you want the longer walk and can manage the terrain, not because a full-day label guarantees every waterfall. Check food, water, breaks and the expected finish with your guide.
Decide for the whole group
Think about recent walking experience, comfort on steep or wet ground and the youngest or least confident participant. Ask the guide to describe the most demanding section and possible adaptations.
If you are unsure, discuss a shorter suitable route. A well-matched experience leaves time to notice the forest and water, instead of concentrating only on finishing.
