Log Swings are an obstacle of Fall Guys, first introduced in Season 5 (Legacy).
Obstacle Description[]
Log Swings are large, pink, cylindrical logs suspended by ropes. They slowly swing back and forth and are quite similar to Thicc Bonkuses with important differences: they are larger, slower and it is possible to walk on them.
Bubble Trouble[]
One of the five zones of Bubble Trouble consists of a Log Swing suspended above a Blizzard Fan, surrounded by four Rotating Hammers. Bubbles will spawn below, above and around the log.

This log swing in Bubble Trouble allows players to reach bubbles that are too high up, but also make it harder to use the Blizzard Fan below.
Lily Leapers[]
Exclusively on Hard Mode, Lily Leapers may feature a pair of Log Swings hanging horizontally above each side path just before the finish line. They may move players on top of them across or knock them down if they try to use the lily pads below.

Lost Temple[]
One of the many possible rooms in Lost Temple consists of a deep pit with a Log Swing suspended above it. Players who fall in can get back up via Blizzard Fans.

Treetop Tumble[]
A pair of Log Swings are located just before the final section of Treetop Tumble, swinging sideways. Players must walk on them in order to remain on the upper path.

Moving on top of these log swings is necessary to remain on the upper path in Treetop Trouble.
