There’s a party atmosphere round the lighthouse on Chanonry Point near Inverness, the UK’s best place to see dolphins from land. It’s an hour after low tide and there are pipers, picnics and kids running barefoot over long, evening sands. Already in late spring, the sun barely seems to set in the Highlands. The kelp-strewn pebbles are glowing as I walk from the bus stop near Fortrose cathedral (bus 26/26A from Inverness) along one side of the promontory. The dolphins don’t show up. But, somehow, it’s fine – the first of many reasons to return. It’s still light as I walk back along the beach for a 9pm bus, past wild lupins and views of Fort George and pink clouds over the Moray Firth. I’m in Inverness at the start of a week exploring Scotland’s wild north coast by train and bus.
