Guide:Travel

Due to the many important biomes and structures in the world, exploration is a big part of Terraria. However, since most of them are far from the spawn point, travelling can be very time consuming.

Below are often-used methods that can make exploration far easier and faster.

Navigating Uneven Terrain
Because of the fact that the world's surface is not fully flat, it can be quite difficult to travel from one side of the map to another in order to visit points of interest, such as the Jungle or the Dungeon.

Equipment

 * While flying with Wings, an Ice Rod can be used while gliding, as touching its Ice block will reset the Wings' flight.

Terraforming
Players can flatten the uneven terrain by mining: you can flatten the top of small rises, fill in small dips in the ground, tunnel through larger natural elements like Mountains or Hills, and build bridges with Platforms on chasms and lakes.

Early on, hammering the top of a two-block-tall pillar to the slanted variant allows for very steep climbs. In the case of a taller, steeper mountain, it is easier to place Ropes or Platforms for faster climbing.

Minecarts
One of the simplest yet fastest forms of travel. A Rail track can be easily built above ground or inside an underground tunnel.

Basics
There are 3 track components:
 * Minecart Track, made with Iron Bars and Wood at an Anvil.
 * Booster Track, purchased from the Mechanic for each. Direction of boost can be switched using Mechanisms or a Hammer. Mainly used to instantly accelerate or decelerate a Minecart.
 * Pressure Plate Track, made out of a regular Track segment, and a Pressure Plate. They can only be placed horizontally.

Tracks can be laid in the air without support. You can grapple to them, but you will pass through them when walking or flying normally.

Behavior
Hammering the rails at the end of a track changes its behavior:
 * Closed: The default option, stops the Minecart in place.
 * Bumper: It reverses the travel direction.
 * Open: It's an unprotected track, causing to the Minecart to fall.

When two tracks intersect it is possible to switch branch by using a Hammer or a wire signal. Hammering or signaling an intersection repeatedly will cycle through the possible branches of the intersection. Using a Hammer eventually disconnects the intersection, although this will not happen with a wire signal.

Holding down or  button will force the Minecart to take the upper or lower path of a switch track regardless of the current state. This allows a branching rail network to be easily navigated early on.

Advanced Rail systems

 * Pressure Plate Tracks only work on horizontal tracks, and will cause a cart to derail if they are laid on a diagonal section. If you need to place a Pressure Plate on a diagonal track, place a Platform in the air next to the track on the side you will pass by, and put a regular Pressure Plate on top of it.
 * You can make a safe track section that leaves a house by putting it in its own room with a door made with Actuated blocks triggered by Pressure Plate Tracks. The "door" of the room will prevent the Minecart track from making it unsuitable.
 * On a Track intersection, you can use a Switch or Lever to cycle through the different branches. Additionally, Colored Torches can be used to indicate the branch that is currently active.
 * To make a single Bumper end Track that can send you both up and down without manual input, you will need to build two rows of 3 Rail tracks on top of each other, and then hammer each one a certain amount of times (see picture)
 * Open ended tracks can be hammered upwards to make jumps. With trial and error, many different jumps can be chained together for much faster travel.

Sky Bridges
A Sky Bridge is a long bridge built high up in the sky, usually with only a single layer of blocks or Platforms. Besides the travel advantages, it can also let you intercept Fallen Stars for easier collection as well.

Note that some blocks will also change the biome of the bridge, and this can spawn more dangerous enemies on top of it. If the bridge is too high, Harpies (and in Hardmode, Wyverns) will spawn as well. Even if the bridge is below the Sky Layer, these Sky enemies can spawn above you.
 * Using Platforms instead of blocks will not spawn enemies on the bridge, and allow you to drop down at any point.
 * Dirt Blocks are easy to get, and allows your bridge to grow different Herbs and Strange Plants.
 * Snow is almost as easy, and allows you to grow Boreal Wood.
 * Mud likewise allows for growing Rich Mahogany or Glowing Mushrooms. However, the resulting Jungle Biome or Mushroom biome can produce various dangerous enemies.
 * If the world is in Hardmode, Asphalt offers a massive speed boost to walking speed.
 * Ice is a simple substitute for Asphalt if the player has the Ice Skates.

A skybridge can also make an effective boss arena, maximizing mobility in all directions and leaving a clear line of fire to the boss.

Subway
A Subway is an underground tunnel that is built by digging a long horizontal shaft. As with the Skybridge, Boots can be used to quickly travel through the subway, and Asphalt can be used as flooring.

For ease of returning to the surface from the subway, Junctions can be built at desired places on the map by mining branched shafts. A vertical exit can be made with a Rope or as a long Platforms stairway.

Subways can double as a barrier to prevent the spread of Evil or Hallowed biomes: in order to work as one, it must be at least 7 blocks tall, and must not contain any Corruptible soil.

Hell Bridge
A Hell Bridge is a bridge constructed in the The Underworld. Its main use is to avoid Lava lakes, although it can also double as a farm to gather Fireblossoms if the bridge is made out of Ash Blocks, Blinkroots if the bridge is made out of Dirt Blocks, or Souls if made with Corrupt or Crimson Blocks.

The bridge can also be used to fight the Wall of Flesh more easily without falling in Lava or getting stuck in uneven terrain. It also works as a good farming spot for Underworld enemies, such as Voodoo Demons.

Hellevator
A Hellevator is a vertical shaft of mined blocks, that generally extends all the way from the surface to the Underworld.

It can be easily built with Explosives or with the use of Mining potions. Gills Potions will greatly help when digging through water, while Obsidian Skin Potions do the same for Lava lakes. Avoid building the Hellevator near the Jungle; you may reach the Jungle Temple, which is made of Lihzahrd Bricks that cannot be mined until a Picksaw is obtained.

Similar to the Subway, the Hellevator can also be incorporated as part of your defense against the spread of the Evil or Hallow biomes. In this case, the Hellevator must be at least 3 blocks wide to prevent the biomes from spreading through it.

Riding the Slime Mount or holding a Portal Gun greatly increases falling speed, which reduces travel time.

Depending on how the end of the shaft is reached, fall damage may be a problem. However there are many ways to overcome this problem:
 * Fall damage can be averted using a small Water or Honey pool, at least 2 tiles deep, just above the Underworld.
 * If water is "leaked" into a Hellevator from far above the landing zone, the water will settle at the bottom and won't immediately evaporate. Once it is disturbed (by taking/adding a bucket of water) the pool will then "update" and begin evaporating.
 * Pink Slime Blocks negate fall damage and do not need to be re-positioned like cobwebs, nor do they risk evaporating like water.
 * The Lucky Horseshoe, Obsidian Horseshoe or Wings can be equipped to eliminate fall damage.
 * The Grappling Hook, Cloud in a Bottle, Flying Carpet, or Rocket Boots can be engaged just before landing, though this requires timing. A Depth Meter is useful for noting when you will be approaching the bottom.
 * You can also use a Featherfall Potion to negate fall damage, provided your fall is not too long. You can press and hold the down key to accelerate your fall when using this potion.
 * The Cobalt Shield or Obsidian Shield will prevent knockback by any enemies who find their way into the shaft through side entrances. Getting hit by an enemy can result in an unexpected and nearly immediate death if there's room to the opposite side.

Skylift
A skylift is a tower-like construct, used to get to Space more easily.

There are five types of skylifts:
 * Ladder: A skylift built with Platforms.
 * Rope: A skylift built with Rope. A player climbs the rope.
 * Teleporter: A skylift built with two Teleporters linked via Mechanisms. Player stands on the Teleporter, triggers the switch, and is instantaneously transported to the other one.
 * Hoik: A skylift constructed by using Hammered and Actuated blocks.
 * A Stair elevator - A skylift constructed from stairs (platforms) placed above each other.

Teleporters


The fastest form of travel, but also the most expensive and time consuming, as it requires a large amount of Wire for greater distances.

To use, you must wire two Teleporters together and then trigger them with a signal, such as that from a Pressure Plate or Switch. With one wire color, each end of a Teleporter pad can be wired to one destination each, making two possible destinations (each must have its own triggering mechanism). Using all four wire colors, each end of the Teleporter can be wired to four destinations each, for a total of eight possible destinations (two red, two blue, two green, and two yellow ).

The Grand Design is incredibly helpful when wiring teleporters at long distances, as it can instantly place Wire over the world.

Hoik
Hoiks are exploits in which sloped blocks are used for fast travel. This occurs when a character sprite shares space with a sloped block: The character is immediately displaced a couple of tiles in a predictable direction.

By chaining Hoiks together with a line of strategically placed shaped blocks, entities can be moved rapidly in any direction. Hoiks have an horizontal travel speed of 60 to 120 tiles per second, while vertical travel speed is 180 tiles per second.
