The soldiers guarding this castle are the ones who blew it up. In 1692 they packed the gatehouse with gunpowder and marched out, so that no Jacobite would ever find it fit to hold, and left behind one of the most photographed heaps of stones in Scotland. Nearly half a million people a year now visit that heap — 466,420 of them in 2025 — not because the ruins themselves are spectacular but because they stand on a rocky headland thrusting into Loch Ness, so that every picture looks like a book cover. It sits half an hour south-west of Inverness on the A82, an easy half-day out from the town. You enter through a visitor centre dug into the hillside, where a short film on the castle's history ends with a neat trick: the screen's curtain draws back onto the real view of the ruins with the loch behind them. Then a steep tarmac ramp and a bridge take you inside the walls. The main survivor is the Grant Tower, five storeys when it was built and shortened when its south wall came down in a storm, climbed by wooden stairs for the best view up and down the loch, along with the footings of the great hall, a cramped, dark prison cell and a full-size trebuchet that children love. The audio guide is included in the ticket. Honesty demands a caveat: the ruins are modest, three-quarters of an hour covers them, and the whole place lives on its setting rather than its architecture. Tickets are timed and sell out days ahead in summer — about two weeks ahead at the peak — and once they are gone online nothing is sold at the gate. Add parking to your booking: it is free but the car park is small and only a reservation guarantees a space. Coach parties fill the site between eleven and three, so arrive for the 09:30 opening or in the last two hours. From April to August the castle stays open until 20:15, with last entry an hour before, and the light on the loch after six is the best thing you will see here. September closes at 18:00 and winter at 16:30, and the wind off the water on the headland is cold and wet, so bring a proper rain jacket in any season. Without a car, Stagecoach buses 917 and 919 from Inverness stop at the castle gate in about forty minutes, or take one of the Loch Ness cruises that land at the castle's own jetty. With children: a pushchair rolls down the tarmac paths right into the castle, though the ramp is steep, and the Grant Tower is a narrow wooden staircase. There is no prayer room; the visitor-centre café looks over the water. Pair the visit with the Loch Ness exhibition in Drumnadrochit, two kilometres away, to finish the monster story for the little ones.

In summer, book days ahead — about two weeks at the peak: tickets are timed and sell out, nothing is sold at the gate once they are gone online, and the small car park is only guaranteed when reserved with your ticket. From November to March you will usually get in on the day, but booking online saves £2 per adult anyway.
The best picture of the castle is from the water, so if time is short the cruise alone gives you the famous view with no ticket. Landing is worth it if you want the Grant Tower outlook or have children keen on the trebuchet and the prison cell; allow an hour and a half including the visitor centre.
