Had a great 2 hours here.
They warned us when we got there because we had an infant to take the short track and don't take your stroller, we ignored them, went back for our stroller and missed the turn off and took the long track by mistake, had to stop at the top for 30 minutes to resuscitate each other. But so glad it worked out like that, had an awesome time exploring the place, came away with some of the best photos of our holiday. Plus you can do a self guided tour by yourself which is excellent if you want a nice peaceful time wandering around at your own pace. Customer service was outstanding but was a little pricey at $20 each to do a self guided tour which is the only reason I haven't rated higher.
