The aim of the present study was to analyze some indicators of impact caused by visitors to Pico Marumbi State Park - State of Parana, Brazil, selecting the most significant ones to be monitored. Data were collected from December 1996 to March 1997 and compared with those obtained in adjacent areas, but without recreational use. The results were analyzed using correlation matrix, factorial and discrimant analysis. The most significant indicators for Pico do Marumbi were micro and macroporosity, penetration resistance at 0-5 cm and 5-10 cm and bulk density.
