Dinosaurs Roar
We get to do so many fun things once you have kids, like go to a dinosaur park in 100 degree heat. No really, it was a lot of fun! Just hot. If you're in the Austin area and you have littles, it's a must do, especially if they're into dinosaurs.
It's a half-mile loop. with full-size dinosaur replicas and fossils. Each stop has information on the dinosaur presented and if you have an interested audience they can learn a lot. The trails are well-groomed, stroller-friendly trails in a wooded area. We didn't notice any mosquitoes, but bug-spray might be a good idea.
We packed a lunch and ate at the covered picnic area by the playground which also has some dinosaur related activities, like digging for fossils and even a Jurassic Park jeep and scene setup to enjoy. It is fairly inexpensive day if you can get out of the gift shop (which is where you enter and exit) souvenir-free.
