Once you get used to the chaos tunnel dragons, they are faster and much more effective. They're more efficient than the wilderness Dragons in terms of consumption of food, but they also have they also offer the benefit of being out of the wilderness (no revenants or their pesky teleblocks), much less overcrowded (only 2 hops to find a world without anyone) and closer to banks than wild dragons.
It's a better environment in general because of these factors. If you have a house with a mount glory and an alter, take house teletabs/runes and recharge pray there and then teleport to the edge to bank/restart trip. If not, you can use varrock teletabs/runes, bank at the east branch of varrock, and recharge prayer at the alter to the north. You will find the dungeon entrance at the top of the "Mapped by Flippi273 box". Run south through the cavern and then use the portal to enter the room with the green dragon. To reduce the amount of food wasted, ensure that you have used all of your prayer before you begin using food.
