Adventure is one of 14 trophies that the player can earn in the game, Journey. It is a bronze trophy, and is worth 10 points.

"Pass through 15 Gates while surfing through the Sunken City"
The key to obtaining this trophy is reaction time. Learn to make sharper, quicker turn when a gate is close yet very much to the side of your current path. You can also fly into the air to slow yourself down, giving relative time to plan your next moves.
