Is the exhibit on the inside

Only a small museum is inside. Dinosaurs are outside along a walking path.

It's mainly outside along a walking path, so if it starts raining, you'll be outside in the rain. Take about 30-45 minutes to slowly walk the whole outside, and the indoor exhibits are a small theatre in one building, a walking maze of info in another, and the main building is a shop.

Some inside but large dino displays are outside.

Yes, many are, main attraction is not
