What Travellers Say
Reviews Summary
Visitors consistently praise Fort Knox for its well-preserved historical architecture and the engaging experience of exploring its grounds. The Penobscot Narrows Observatory is lauded for its breathtaking panoramic views, making the combined ticket a highly recommended value. Some visitors wish they had more time to explore the fort thoroughly.
"We visited here on our way from Camden to Bar Harbor. I separately reviewed the Penobscot Observation Tower which was also a great experience.
Upon arrival in the parking lot you are given the option to purchase a ticket for just the Fort or for the Fort and Ovservation Tower; there is no Observation Tower only. Our priority was the Observation Tower and ww used what time was remaining to explore the Fort.
There is a gift shop and restrooms you pass on your way into and back out of the Fort itself. The first thing I noticed was how intact the structure of the Fort was. Many of the ones I have seen in other places are reconstructions or ruins with walls crumbling.
My husband and I explored a good bit of the area, although not all of it due to time constraints. I loved that you were able to walk through the same places soldiers did 200 years ago. The views from outside the walls were also incredible and very much worth stopping for on a sunny day.
Overall, a truly great slice of history. We were just 2 adults, but I imagine kids would also love exploring this place, too.
Highly recommend, especially as a way to break up the drive to or from Bar Harbor."

"Stumbled upon this gem during our drive back from Bar Harbor to New York City. Located about an hour west of Bar Harbor/Acadia along Route 1. Saw a beautiful bridge and signs for “Fort Knox” observatory and headed toward that direction.
Admission to the Fort alone is about $6.50 for out-of-state visitors and combined with the bridge observatory (recommended) is about $9.50.
After paying the fees at the gate, you can either head to explore the fort or down toward the bridge’s observatory deck. There is a separate parking area for the bridge observatory.
Once there, you head down along the path to the bridge’s tower entrance. You then take an elevator up to the top. From there, there are two short flights of stairs to get to the top/observatory section. The views there are spectacular…more than worth the nominal price of admission. The elevator operators/greeters were both super nice and very informative.
The fort itself is also great with lots of area to explore on multiple levels. The top and bottom levels offer some great view of the Penobscot River.
The gift shop there is also nice…lots of souvenir and snack options.
All staff we encountered were very nice and helpful."
