I believe it was 20 per adult and you can take a partial, in and out, tour if you have a disability. They are very friendly and accommodating. You can't keep the gold you pan for though. :-)
I don't remember the cost I think it was 20-30 a person and you walk through it. It's multilevel so you do need to climb a 7-8 foot ladder. So it's definitely not for someone who has a physical impairment.
