About Inverness

Inverness's castle and river walks lead along the Ness to the Caledonian canal and Loch Ness, with Culloden battlefield and the Moray coast close by. The North Coast 500 starts here, and the Cairngorms and Isle of Skye are within reach for longer drives. May to September is the warm, busy season; spring and autumn are quieter, and winter is cold with snow on the hills.

Travel Tips

01Loch Ness Tour Hours
Boat and bus tours to Loch Ness and Urquhart leave in the morning; afternoon returns can miss last connections. Long summer evenings suit riverside walks.
02Buses Across the Highlands
Citylinks and local buses reach Highlands destinations; the centre is compact. Car hire helps for Glen Affric when buses are sparse.
03Castle & Cruise Fees
Inverness Castle viewpoints and Urquhart Castle charge entry. Ness cruises are optional add-ons - compare inclusions before buying.
04Midge Season Prep
Late spring to early autumn brings midges near water - repellent and long sleeves help at dusk. Always pack a rain layer in the Highlands.
