Successfully complete the indicated task to reach the indicated hidden level or mini-game:
Flying Fire Rings
In the "Wormholin' – Observatory" level, drop from a cliff to see fire erupting from a pipe. Drop onto this ledge and reverse to set the rear side of your bike on fire. This will make several fire rings appear in the sky, and you will be able to fly through them to reach a wormhole on a stationary aircraft in the air.
In the "Return Of The Sphere – Around The Oasis" level, reverse to fall into the water near some pipes. You will be able to play a Marble mini-game that was also available in Trials: Evolution.
Near the start of the "Secret Agent – Cliffhanger" level, reverse and fall into the open hatch of the stationary UFO to be transported to the secret Maze level.
At the start of the "Penguin Wash – Stormtrooper" level, reverse through the sand ramp, and enter the purple glow near a truck to enter the secret level. Destroy all towers and make the birds fall to complete the challenge.
In the "Game, Set, Match – Park And Ride" level, carefully drop down onto the tennis court, and wait in the middle of the court to start playing tennis against a penguin, using a signboard.
There are five hidden Ninja difficulty tracks in the game. To unlock each of the secret tracks, successfully complete an Extreme difficulty track with zero faults. Then at the end of the Extreme difficulty track, bail out just before driving across the completion marker. If you can successfully shoot the driver into the cave, hole, or object past the marker, you will start back at the beginning of the track on the Ninja difficulty. Each Ninja track is an extremely difficult variation on the Extreme track. Ninja tracks were originally created in the Trials: Evolution editor by the fan community. Only the best players can complete these tracks, which often require unique or unintended maneuvers to complete.

Search the indicated locations to find all 20 squirrels and get the "Bright-Eyed & Bushy-Tailed" achievement.
Select the "Create" option at the main menu. Then, go to the following location in the large mountains on the western side of the map (west of the city). It is in the mountain range north of the desert, but southwest of the snowy zone. First, create a start and end point for the track to make objects available. Select the top of the mountain zone. Then, create a "New Object", and select "Terrain" then "Environments". Edit the properties so the object is a hole and "Crater 5", and remove the decal. After creating one hole, select it and copy the object. Start placing the holes all around the top of the mountain to eventually uncover the secret key. Zoom in and grab the key to get "The Fifth Key" achievement.
