Tidnish is located at the northern cusp of Nova Scotia's mainland, near the New Brunswick border. Tidnish, a member of Cumberland County, can be reached traveling on the beautiful Sunrise Trail (Highway 366) and is also near the shores of the Northumberland Strait.  The first grants received at Tidnish occurred in 1816, by Peter McElman and Benjamin Goodins.  Tidnish was supposed to be the eastern terminus of the Chignecto ship railway in the late 1800s; unfortunately, the railway was never completed. Tidnish is only 24.7 km (15.3 mi.) northeast of Amherst.

Tidnish is a proud home of the Tidnish Information and Interpretive Centre, which delves into the history of Tidnish, enlightening visitors of the forgotten railway, life in the 1800s and much more. As well, the centre features a hiking trail that follows the abandoned railway. Tidnish exhibits its very own national park, offering a rocky beach, a picnic area and picturesque views of the sea and the land. A celebrated stone bridge of the abandoned railway still stands today and is considered a tourist attraction.

Tidnish accommodations include hospitable cottages.
