Worth going? depends on a number of things..
If you've got nothing better to do on a given day, it's an okay day trip, but don't expect much from it alone necessarily.
If you have your own transportation then its an inexpensive time killer. If you're hiring a van etc, then you may feel the money wasn't well spent.
We went maybe 5 yrs ago on a rented scooter. The trip was more fun than actually being there. I don't recall the road to get there being a problem, seems like it was all paved.
Fast this Life of mine was dying
Blind already and calm as Death
Snowflakes on her bosom lying
Scarcely heaving with her breath
Love came by, and having known her
In a dream of Fabled Lands
