The Loch Ness Centre in Drumnadrochit approaches the mystery of the monster with more intelligence than you might expect from a tourist attraction built around a myth. The exhibition runs through the history of Nessie sightings, the various expeditions that have attempted to find something in the loch using sonar, cameras, and DNA analysis, and the scientific case for what the loch actually contains. It neither flatly debunks the legend nor encourages credulous belief — it presents the evidence honestly.
The loch itself does genuinely hold surprises. It contains more fresh water than all the lakes in England and Wales combined. It is so dark with peat particles that visibility below the surface is essentially zero. Strange things have been filmed there that remain unexplained. The exhibition makes a good 90-minute visit, particularly useful for managing younger visitors' expectations before the disappointment of not seeing a monster from Urquhart Castle.
