• A long, narrow staircase of roughly 300 steps leads to the prints, and the steps get slippery when wet, so hold small hands and leave the stroller at the beach
• Midday light works best, when the sun falls across the rock face and the prints stand out; in flat or low light they are hard to spot
• Praia Grande sits right below, a big sandy Atlantic beach with strong surf, so pack swimsuits and make it a beach day

A stone staircase at the south end of Praia Grande climbs beside near-vertical limestone slabs printed with 66 three-toed dinosaur footprints, 51 of them lined up in 11 trackways. The slabs formed on a shallow sea floor and were later tilted upright, so the tracks now run up the cliff face.

Kids can count the prints on the way up, then head down to the wide surf beach below.
