Neptune's Staircase is a cool set of eight locks on the Caledonian Canal in Scotland, built by Thomas Telford back in the early 1800s. It's like a giant water staircase that lifts boats up 64 feet, making it the longest of its kind in Britain. The locks used to be operated by hand, but now they're all fancy with hydraulic power. It takes about 90 minutes for boats to pass through this watery stairway, and the lock gates are massive, weighing 22 tons each! So, if you're ever cruising near Fort William, swing by Neptune's Staircase for a unique canal experience.
