This a review of the Acadia National Park, including the park loop road and Thunder Hole. The park is very pretty, with nice views from Cadillac Mountain and on the loop road. Thunder Hole was interesting, and we did get to see it in action. Honestly, my wife and I were not mesmerized by this park. Most of the western national parks are much better. We liked it, but I think it is overrated.

I won't go into the view and the facilities because they have been well covered by other reviewers. But I'd like to share a tip: Once you made a reservation for your 30-minute window, you can change it as many times as you like, subject to availability. Obviously this won't apply to the always-booked sunrise hours. But if you have a daytime reservation and find that your day in the park is going slower or faster than planned or if the weather changes, and if you can get a data connection, you can sign in to recreation.gov and change your reservation to a different time on the fly. I did this twice during our trip, the last time 15 minutes before the new time slot from Hull's Cove Visitor Center parking lot, where I managed to get a 2G connection.

We had an early entrance ticket. It was drizzling, but we could see some sun peeking out. There are several hikes. The two we chose were excellent; one was to the highest point marker. There’s an eco gift store which had coffee and gifts. We had a grand time even in the rain.

We had a daytime reservation for the morning but arrived early and was let in. We were told it gets busier between 9 a.m. and noon. After heading to the summit, we found a parking spot and entered on the path closest to the parking lot. Views were incredible and we continued on the trail until it exited, still near the parking lot. Along the way there are several scenic stops for great views and pics. Highly recommend!

Short drive to the top of Cadillac Mountain. There is a path to walk around and the views are stunning. A must see it going to Acadia National Park. Don't forget to get a timed entry pass.

Beautiful sunrise. We woke 4 am, drove up at 5 am. Saw the sunrise. You need to reserve in advance. Dress warm. Hats and gloves and blanket. Bring hot tea and coffee. It's cold up there and windy,. The we hiked down and back up Cadillac Mountain. Fairly gnarly at points. Lots of rocks, boulders, uphills and tough climbs. We are in our 60's and did it down and back up. Bring 2 water bottles and hiking poles for support. Beautiful views.

We made a reservation for 5:30pm to see the sunset as we were unable to obtain sunrise tickets because they sell out so quickly. We were able to obtain parking in the west lost but it is a small parking lot. It seemed most people parked in the bigger east lot and walked over to the west lot. We took blankets to sit on had a good time watching the sunset. We also took jackets as it was a little chilly.

We made our reservations for 7am. Got a little lost looking for the entrance road, but showing our reservation and America The Beautiful pass was easy. Parking was easy at the top. There was still a lot of people up there, so I cannot imagine if it wasn't regulated. We walked all over, and couldn't find the summit. Went to little store to use the toilet and buy coffee, and figured out that the summit was behind the store. After the big push, we made it to the top. :)

Utterly stunning experience. We did sunrise and with the sea fog the colours were just amazing. The tickets for sunrise sell out within 3 minutes so set a reminder on your phone and be ready! We also hung around and did the Hawk Watch for a bit which was really interesting.

The park controls access to the mountain top very well. Plenty of parking spaces. Which is more than I can say about the rest of Acadia which was overcrowded, parking almost non existent. We went at 1:30 in the afternoon on a clear day. Views were excellent. It's not quite what I thought it would be in terms of height, but still worth the experience. Short drive up the mountain. Expect wind and cold.
