The Queen of all of Nova Scotia’s driving routes – the Cabot Trail – is typically littered with superlatives such as best, greatest, and most scenic. It certainly deserves praise as it provides a whole different feel of Nova Scotia than the other routes. The road hugs the cliffs and winds around forests on the Northwest side and the Eastern side provides a rocky coast dotted with fishing villages and beaches. There are plenty of scenic lookouts along the Cabot Trail giving you many photo opportunities or just a place to sit and take in the magnificent views.
For part of it you travel through the Cape Breton Highlands National Park where you'll find many hiking trails that take you to even better views.
Be sure to get off the main driving trail too and take the side roads like White Point road to little fishing villages where you'll find super food, lighthouses, and a more local feel.
In fact - I suggest that you spend a few days on the trail instead of driving through it in one day. There's so much to see and do in the park and surrounding communities!
