Mammoth Waco is a primary university site with NPS umbrella so passes do NOT help but the small fee is well worth it. It goes to maintaining an amazing place
I'm assuming people answering questions have not been here because while it might be run by NPS and one can assume it uses the pass, it does not use the national parks passes and requires fee for the mandatory guided tour. Says right on website plus if you attend, you will hear the same answer
No, since this is not a State park. You can use your national park pass, though.
Not sure, if state passes are excepted for discount. It's a national park, but there are discounts for military and students.
I don't think so.
I'm not sure what a Texas State pass is but this is a National Monument site and therefore interagency passes areacceptible
I guess you could
