Legend is in the image.
Brown arrows show route to take to get all 5 collectible coils in one go, needing to backtrack at some point after the hatch in the bottom right. Routes to take there are numbered 1 and 2 in sequence.
For the first purple Experience Tesla Coil, if the gate below is closed, you can go from the top and fall down and climb back up again (the lighter brown arrow), but it is risky as the gate only closes when the lava is already close.
