Depends what you want from it. Unless you're lucky, you'll be crammed in an old, uncomfortable cabin with wooden benches as you bounce around to the top of the hill.
But it's much easier than walking, there's an absolute charm to it, and you can get some stunning pictures on the way up.
It's cheap, but it doesn't seem to run to schedule and the lack of information available means queues can often build up quite quickly without any indication of whether it will be a 5 or a 50 minute wait.
