Delightful small town on the far north of Scotland. There are lots of shops and nice places to eat in the area. There aren't many places this north of Scotland where you can stop off for provisions so Thurso really is ideal for that. Not a lot in the town to see but worth an approximately 2 hour walk around and stop for a bite to eat. Surfers descend on the area in the summer months.
Thurso at the northern end of the Far North mainline which runs from Inverness and splits into two branches, one going to Thurso and the other going to Wick. The train station is located a very short walk west of the town centre.

Holburn Head, Thurso, Scotland
Hike to Holburn Head: There's a lovely hike to get a good sense of the North Coast with views of the Orkney Islands and Dunnet Head in the distance. There's no real trailhead, all you must do is start at the esplanade / beach in Thurso and follow the coastline west to the harbor and then walk along the tarmac road to the gate by the Scrabster Lighthouse. Then just follow the marked path from the gate. The entire hike cuts across some rock shale formation, headlands, pebble beaches, the Scrabster Harbor, and a few pastures. For some more dramatic cliffs, sea stacks, and geological formations, keep heading west from Holburn Head. 
Groceries are available at Lidl, across the road from the Campground on the Scrabster Road.
