Did you know that the Parque Cretacico in Sucre, Bolivia is now organising tours right down to the cliff face to see the dinosaur footprints up close?
Here's a brief explanatory video someone posted:
These tours run at 12 mid-day and 1 pm when Fancesa employees are at lunch and there is no danger of rocks falling as a result of cliff blasting. You have to wear enclosed shoes to be allowed on the tour, i.e. no flipflops or other sandals.
