The Museum of Nature & Science at Fair Park has lots of things to see & do. Be sure to visit the Museum of the American Railroad. They have lots of trains that you can walk into on your own. One of the engines has a train whistle that you can blow. We always find that to be fun ! Tickets range from $5 to $7 per person. I would suggest the Fair Park Passport which includes 7 museums (including the trains) for $11.99 for children and $19.99 for adults. It’s valid for 90 days from the date of purchase.

You might consider going to an IMAX movie at Fair Park in Dallas, or an Omni movie in Fort Worth. The Omni (my favorite) is showing, "Grand Canyon Adventure", and the Imax has two features, "Hurricane on the Bayou" & "Coral Reef Adventure".

The Omni Theater is the more effective experience, but if you have older people who can’t climb stairs, I would suggest the IMAX at Fair Park. This is due to the fact that the Omni upper seats can be pretty steep and scary for really small children and older adults. Although some children will find it exciting just like a roller coaster ride! I guess that’s how I would describe the experiences. The IMAX is like a regular theater only better, and the Omni is like an exciting and a little scary, amusement park ride!
