This lovely 40-mile spring drive will only take about 3 hours. Every minute spent on the road is worth your time. Along the way you’ll get to see, explore and marvel breathtaking beaches, foliage, hiking trails, incredible swimming holes, islands, ponds, lakes and rivers, mountain and ocean views, and wildlife. The byway follows Route 3 into Bar Harbor, and then follows the park loop road thereafter, according to Explore Maine.
