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.

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. You can also hold an Umbrella to greatly extend the distance gained from jumps.

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.
 * 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 Glowing 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.
 * Using sand blocks and Dunerider Boots also works as an Asphalt substitute.
 * A bridge made of frozen slime blocks makes for a fast, hands-free method of travel, similar to a minetrack. This is especially effective when using a grappling hook to accelerate, and even more so if using a Portal Gun.

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.

The Digging Molecart is perfect for digging subways, as it places tracks and mines blocks itself, and is meant to be used underground.

Note, that if for some reason you need or want to tunnel through the desert (though this is a good reason why tunnels should be a good distance below any deserts, it's always a good idea to survey the landscape before you embark on any major construction projects), there is a way to tunnel through the desert biome without mining everything above, and it involves bombs. Because there is a delay in ticks between the sand blocks falling and forming, it is possible that with a grappling hook, position yourself at the top of some tunnel, set a bomb to go off near the edge, and quickly place dirt blocks or another solid block as soon as the explosives go off. This will be very slow, but it is possible. However, if you just dig a little deeper, you should hit hardened sand and sandstone blocks, which can be easily tunneled through. On the, if equipped with a Cobalt Pickaxe or stronger, you can use Block Swap and place blocks not affected by gravity above you. This stops the sand from falling down.

Hell Bridge
A Hell Bridge is a bridge constructed in 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 Ebonstone, Crimstone or Pearlstone 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 and Mimics.

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. Alternatively, if the player has already located the Jungle Temple and has a Gravedigger's Shovel handy, the Jungle can be the best place to construct your hellevator. The Jungle and Underground Jungle are both comprised primarily of mud, which can be easily dug through by the Shovel; this will cut down your construction time immensely, so long as you start digging somewhere with a clear line from the surface to the Underworld.

While a simple hellevator only consists of a hollow shaft, it can also be equipped with periodic rows of platforms, a line of Rope, or a hoik, which can facilitate upward travel. Note that platforms often slow down the descent speed and that using a hoik will still require a mean of negating fall damage (see below). Riding the or holding a  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 avert it:
 * A small pool of water or honey just above the Underworld, where it does not evaporate yet, cancels the fall damage. can be used alternatively.
 * The Lucky Horseshoe (or upgrades) or wings eliminate fall damage entirely.
 * The buff of the Featherfall Potion negates all fall damage as well. Holding while falling will accelerate the fall to the normal speed.
 * The Cloud in a Bottle (or upgrades), Flying Carpet, Rocket Boots (or upgrades), or any hook can be engaged just before landing, though this requires precise timing. A Depth Meter is useful for noting when you will be approaching the bottom.
 * Running a line of any Rope type down the hellevator is a safe way of averting fall damage.
 * Switching to the Bunny Mount at the end will negate all fall damage.

The Cobalt Shield or any of its upgrades will prevent knockback by any enemies who find their way into the shaft through side entrances. Getting hit by an enemy can knock the player out of the shaft, interrupting travel and (if fall damage is not negated) often causing instant death.

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.

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 ).

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 a horizontal travel speed of 60 to 120 tiles per second, while vertical travel speed is 180 tiles per second.

Pylons
Pylons are a new feature added in Journey's End. They allow the player to teleport around the world via the different pylons in the game. They are purchased from an NPC with at least 85% happiness for a base price of 10 gold, for example putting the merchant in the forest will satisfy the requirements and the merchant will sell the forest pylon.

To use pylons there must be at least 2 NPCs nearby and there must not be an active boss or invasion. Pylons can almost be a replacement for standard teleporters in a world, but note the there can only be one of each type of pylon in a given world.

Pylons have many advantages as well as disadvantages.

Advantages:


 * They do not require any wiring
 * They can be obtained pre-boss
 * They allow instant travel

Disadvantages:


 * They require at least 2 NPCs nearby to be functional
 * There can only be one of each type per world.
 * They can't be used during any Boss fight or invasion.
