I usually allow 2 hours for museums (I rather do a second visit) and for this one a single 2 hour visit is adequate.
It depends as there are many displays with stories to read, film which is about 20 minutes outside trail to the jump.... so much information, to fully enjoy it allow minimum 3 hrs.
If you want to do the two trails, one short and the lower interpretive trail is a pleasant 45 minutes. I was there about three hours and enjoyed every minute!
1-1 1/2 hours
