What to know
- The gap appears during the “Find a blue flower” objective in Mountain Climb.
- You must destroy nearby objects to collect building materials first.
- Building the launcher parachute is the only way across the canyon.
- After launch, you automatically land inside the main base area with your companion.
Reaching the other side of the massive cliff in LEGO Batman: Legacy of the Dark Knight can feel confusing at first because there is no visible bridge or grappling point nearby. During the Mountain Climb mission, the game expects you to use a special traversal mechanic tied to the environment. If you are stuck during the “Find a blue flower” objective, this guide explains exactly how to cross the gap and continue the mission.

The cliff crossing puzzle during the blue flower objective
As you move through the snowy mountain section, you eventually reach a large broken cliffside separating you from the enemy base area ahead. At first glance, it may seem like you need a special gadget or character ability, but the solution is actually hidden nearby in the environment.

The game places several destructible objects around the cliff edge. These are essential because they contain the pieces needed to build the next traversal device. Until you destroy enough objects, the build prompt for the launcher will not appear.
You should clear the area completely before attempting anything else.
How to build the launcher parachute and cross the gap
Step 1
Destroy all nearby interactive objects around the cliff edge. Focus on crates, loose equipment, and breakable debris scattered near the ledge.

Step 2
Collect the LEGO pieces that spill out from the destroyed objects. Once enough materials are gathered, a build circle appears automatically.

Step 3
Interact with the build spot to create the launcher parachute. The structure resembles a compact launch platform connected to a parachute-style flying device.
| Build Requirement | Result |
|---|---|
| Destroy nearby objects | Gain building materials |
| Complete build prompt | Unlock launcher parachute |
| Enter launcher | Begin automatic flight section |

Step 4
Get inside the launcher parachute immediately after building it. The game automatically launches you across the canyon without requiring additional setup.

Step 5
While airborne, steer through the sky and collect as many studs as possible. This short flying sequence acts as a mini traversal section and gives you an easy opportunity to increase your stud count.

The controls are fairly forgiving, so you do not need perfect movement to make it across safely.
Step 6
Near the end of the flight, the launcher experiences a short malfunction or circuit failure. This is scripted and part of the mission progression, so do not worry if the vehicle starts breaking apart.

After the sequence ends, both you and your companion automatically fall into the main base area below, allowing the mission to continue normally.
What happens after reaching the base
Once inside the base, the mission shifts away from traversal and returns to standard exploration and puzzle-solving gameplay. You can continue searching for the blue flower objective while progressing deeper into the Mountain Climb mission area.

The parachute launcher section is a one-time scripted traversal sequence, so there is no need to backtrack or rebuild it afterward.
| Section Outcome | What Happens |
|---|---|
| Launch begins | Automatic flight starts |
| Mid-air section | Collect studs |
| Vehicle short-circuits | Scripted event |
| Final landing | Reach main base automatically |
The large canyon during the Mountain Climb mission in LEGO Batman: Legacy of the Dark Knight is solved entirely through environmental interaction. Destroy nearby objects, build the launcher parachute, and use the short flying sequence to safely reach the main base area. Once you land, the mission continues automatically, letting you progress toward the blue flower objective without needing any extra gadgets or hidden paths.
