Boulogne-sur-Mer to Honfleur Road Trip Guide

The N1 highway between Boulogne-sur-Mer and Honfleur traces a route where Roman legions once marched, connecting two historic port towns. At 244 km (152 miles), the drive typically takes 2 hours 45 minutes without stops, but savvy travelers stretch it to a full day. The road passes through the Côte d'Opale's cliffs, the Baie de Somme's bird reserves, and the Pays d'Auge's apple orchards.

A local quirk: the D940 coastal road near Le Tréport offers a parallel, slower alternative to the A16 autoroute—saving €8 in tolls but adding 40 minutes. This guide follows the A16/A28 route for efficiency, with strategic detours. For a deeper dive into hidden gems, see how to find the best stops and hidden gems between cities.
