If you have more time, consider visiting the Gennargentu National Park for a scenic drive, nature hikes and wildlife sightings. For less time, consider splitting up the longer nature park visits into one day instead of two, or skipping the lighthouse visit altogether. It's important to note that some places, especially the beaches, may have varying access fees that are not included in the itinerary's cost estimates.
