🌉 A Crown Jewel of Engineering: Experience the World’s Tallest Bridge Observatory

Ready to touch the sky? The Penobscot Narrows Bridge and Observatory is more than just a crossing—it’s a high-energy, record-breaking destination that stands as the crown jewel of coastal Maine. Soaring 420 feet into the air, this is the tallest public bridge observatory in the world and the first of its kind in the United States.

Taller than the Statue of Liberty and rising 42 stories above the river, the observatory offers a pulse-pounding, 360-degree panoramic view that stretches from the Camden Hills to the distant peaks of Mount Katahdin. Whether you’re an engineering geek fascinated by its award-winning cable-stayed design or a sightseer looking for the ultimate Maine photo-op, this is an unmissable stop on your 2025 itinerary.

🏛️ Explore More: Fort Knox Historic Site

Your journey doesn’t end in the clouds. Directly adjacent to the bridge is Fort Knox, one of the best-preserved 19th-century granite fortifications in New England. Built in the 1840s to protect the Penobscot River Valley from British invasion, this massive fortress invites you to explore dark passageways, climb spiral granite staircases, and stand atop the ramparts for a dramatic look at the bridge from below.

🕘 2025 Hours of Operation

The site operates seasonally from May 1 to October 31.

*Fort itself closes 15 minutes prior to sunset in late autumn. Park grounds remain open 9 AM to sunset year-round.
