About the Track

Circuit Thermalito is a 5.035km fictional temporary race track based on a real life location, using the actual roads surrounding the Thermalito Dam in Oroville, California. Winding its way between the walls along the water's edge, and through two tunnels in the dam itself, Circuit Thermalito features high speed elevation changes, sweeping banked corners and slow speed technical sections which all come together to create an incredibly challenging, yet hugely rewarding, driving experience.

Originally made by DDF Racer ( using limited satellite data 15 years ago for rFactor, Circuit Thermalito has been completely rebuilt from scratch to modern standards in stunning detail by Nukedrop. Crowdfunded on Kickstarter by the DDF Racer YouTube community and using hi resolution laser scan data, drone footage and countless photographs of the area, Circuit Thermalito is now available to download for free for Assetto Corsa.

Due to the drastic elevation changes, this track may not be suitable for AI Races against some of the top tier open wheel race cars.

3D grass, 3D trees, full RainFX, full night lighting, AI, 44 grid sllots.

Please see the config.ini if you wish to use 2D trees instead of 3D trees to save performance.

Fantastic thanks for this gem.
what an amazing track, and such amazing work! ! !
One of the best original tracks in AC that I've ever driven. Super fun and unique layout and beautiful detail.

Also, always really cool when a fictional track is based on a real location and real topography/roads. Modders, take notes!
Really fantastic track - so much detail and I love the location. Very good fun to race!
One of the most detailed fictional tracks I've ever seen. And a fun one too. Super high level artistic work. I'm in love with this track!
One of my favorite tracks since GTR2. Love your remake of this and the new layout. Beautiful Job on this......Outstanding.
Would be perfect with fewer slow corners and finally a first chicane I hate more than Monza. Where do people see races wih hot air ballons?
Thermalito , huahu what a piece of work. Amazing to see NUKEDROP & DDF together. Amazing stuff, please keep it up for future tracks and events ;) Thank you
