Glide to volcano is a mission in Jak 3. Jak recalled Seem said they lost an expedition of monks in the Great Volcano and figured they used monk gliders to reach the top. He then decided to use the one he found after climbing the Monk Temple tower to do the same.
The PlayStation 3 and Vita versions of this mission are related to a trophy named "Is It Hot in Here?", completing this mission will reward you with a bronze trophy.
A flight mission over the Wasteland, where you shoot the accelerator rings using your Blaster (or Beam Reflexor) to activate them and gain more speed. Speed is key to staying alift here, as the bottom bar represents your current speed. Missing one ring is alright, but miss two and you'll most likely fall to the ground. You can hit the rings with just the tip of the wings from the glider but it's usually a tad risky to do so.
Take care to hit the moving rings as well and most important of all; don't avoid the blue jets of air that will lift you up and give you a big boost. After flying around pretty much the entirety of the Wasteland you'll eventually hit the last ring leading into a cutscene as well as the next mission; "Find satellite in volcano".
