Brazil
A five-hundred-metre waterfall drops straight off the rim into a gorge two kilometres wide.
The ground simply stops. Itaimbezinho runs 5.8 kilometres between walls two kilometres apart and 600 to 750 metres deep, and the water coming off the plateau goes over the edge into it: Cascata das Andorinhas falls 300 metres, Cascata Véu de Noiva falls 500. Aparados da Serra is the point where southern Brazil's tableland shears away, and you walk the top of it.
A decree of 17 December 1959 created the park to protect the Itaimbézinho and Faxinalzinho canyons, and its 12,966 hectares hold six threatened species, among them the vinaceous-breasted parrot and the puma. Araucaria forest runs along the rim, which is what the decree was written to save alongside the gorge itself. Getting here is nineteen kilometres out from the centre of Cambará do Sul, much of it dirt road, and the park supplies no guides at all, so a licensed conductor is hired in the town for every trail on the list. The canyon-floor route trips people up: the Trilha do Rio do Boi starts in a different state, at Praia Grande in Santa Catarina, covers 8.3 kilometres there and back over five to seven hours with a credentialed guide, and the Itaimbezinho ticket does not include it. The state tourism authority names July as the month to come, and the reason is worth knowing, because July is when fog is least likely, and fog is what turns a day up here into a white wall.
Solo
A hired conductor comes with every trail, so arrange one in Cambará do Sul the night before and take the first entry of the day. Mornings are when the canyon is most likely to be there at all.
Couple
Do the short Vértice walk first for the two waterfall viewpoints, then the Cotovelo along the rim after lunch. The ticket runs to three visits in seven days, so the second one can be Fortaleza in the neighbouring park.
Family
Both rim trails suit walkers of any age, forty-five minutes on the Vértice and about two and a half hours on the Cotovelo, but the Cotovelo closes to new walkers at three in the afternoon. Carry lunch and water, since nothing at all is sold inside the gates.
