The circuit is widely considered one of the most technical in Italy, with features that have made it a benchmark in the motorsport world. It is homologated by FMI and ACI. Over the years, with experience, all the most exciting specialties on two and four wheels have been integrated. The circuit regularly hosts national, international, and world-level races for both two- and four-wheel vehicles.

Castelletto Circuit is universally recognized as one of the most technical medium-slow tracks in Italy. Its carefully designed layout is the result of years of testing and small modifications, ultimately creating an adrenaline-fueled mix of corners, elevation changes, and straights that continuously challenge drivers to improve their lap times. Unlike many other circuits, Castelletto captivates a wide range of drivers.

It is not only a track for Legends Cars drivers but also attracts rally drivers, road racers, hill climb specialists, drifters, and many other categories on both two and four wheels. After years of hard work, several world-class teams (rally, drift, supermoto, etc.) have made Castelletto one of their preferred stops for fine-tuning their cars and bikes and training their drivers.
