    Thunder Hole is a section of the rocky Acadia National Park shoreline where the water crashes against the rocks spouting high in the air. OK, that's what I read/heard but again you have to time it to see/hear the sound. there were bus tours and it seemed the passengers were disappointed, but I did hear a bang sound. This is a beautiful stretch of coastline. when we went there- that tipping point- it was closed. Parking: There is a parking lot across the street.

    Bottom Line: Perhaps a fun spectacle two hours before high tide otherwise just a view point with a lot of other people. I've consistently heard the best time to visit Thunder Hole is two hours before high tide. But I couldn't get excited enough about this stop to prioritize being there two hours before high tide so we went about our day hiking and got to Thunder Hole an hour after high tide. The views were beautiful and we enjoyed them along with 20 other tourists all in the corral aka safety rails. The noise an hour after high tide sounded a lot like the low, guttural gurgling noises my toilets made the last time the local water municipality flushed our water mains. No joke. When it comes to National Parks I am more about exploring trails away from the crowds versus stopping at sights that attract crowds so that is why this wasn't high on my list. Another reason this attraction didn't get me too excited is that Thunder Hole reminds me of some of the blow holes I've seen in Hawaii.

    When I first heard the name my first thought was another name for someone's bum, but there is a reason for the name, there is a unique sound when the waves hit the inlet, which is a small cavern which trap the air and causes the distant thunder sound, that's a according to the fact from a souvenir magnet I got. Yes Thunder Hole is a mini attraction within Acadia National Park. If you're lucky at the right time, with the right tide and if it's not crowded with people you'll be able to see water forced through a hole creating the sound of it's namesake. Unfortunately during my visit I did not see it and even then there were quite a few people so if you bravely come here in the colder months it you may be better off as there will be less people and the conditions may be more in line for it. The stairs down to the viewing area is nice and maintained. There is also a park plack that talks a bit about it as well. There is a parking lot dedicated to this section of the park and parts of the intersecting trails pass through here so you can drop in on it and not even really know, unless of course you're following the park map. There is a souvenir shop that has the usual Acadia National Park merchandise but of course they have Thunder Hole specific items too. While you're out enjoying Acadia National Park stop by Thunder Hole maybe you'll see the splash and hear the thunder.

    Our timing was off, so we didn't get to experience the loud thunder. Regardless, we enjoyed the cloudy sky, soft rain, and the wave breaking against the cliff. The gloomy weather made the experience more intense. The bonus was that the crowd was minimal.

    This sign has info about the ocean currents that affect the temperatures of the waters in the area.  Photo taken October 2, 2019.

    Thunder Hole is a natural landmark found inside Acadia National Park. It is located on the southeastern part of the park. This was one of our stops during our tour of the park. Across the street from the main attraction includes parking, gift shop, and restrooms. My visit here was on October 2, 2019. When we got to Thunder Hole, it was busy, but not overcrowded at least. The weather was cool and overcast with temperatures in the 50s. The timing of the visit was a little over an hour before high tide was to occur. We were given about 20 minutes to visit this area. Most of my time here was taking in the views and video of Thunder Hole (videos are too big to post). I did get one good one while there and could work well as a white noise machine too. The views were breathtaking. Thunder Hole was made through natural rock formations. I was able to hear the thunder a few times as the waves were forcing the water out. Some of them came up looking like a big geyser exploding. This makes it a beautiful natural phenomenon. I was on one of the open paths down toward the hole area up until where the sections below were closed off for safety reasons. During the visit, there were quite a few people also on the rocks there. For the most part you would be fine on the rocks, but make sure that you aren't on any of the wet or black rocks. You could get swept out to sea. However, they do provide for some great views. Overall, Thunder Hole was definitely the highlight of my entire trip through Acadia National Park. With the stunning views and sounds, what is not to like about this place? Just be sure to time it right with the tide cycle when you visit. I would love to come back at a later time where I have more time to visit this place. If your travels take you this way, this place is definitely worth stopping and visiting.

    Thunder Hole, one of the more visited parts of Acadia National Park, is fantastic when you catch it at the right time, underwhelming if you don't. The guide book I had on the park outlined this so we tried to time our visit to get the best experience possible. Basically Thunder Hole is a cavern that, when slammed by ocean waves during high tide, makes a huge crashing sound akin to, well, thunder. We were lucky enough to make it there during the rising tide and a windy day, which made the choppy water crash into the rocks in a very impressive way. Perhaps not as loud as you would get at peak high tide (or on a stormy day) but it was enough for us to see what all the fuss was about. The rock formations are beautiful tho, so you won't have a bad time here. You may just not get the full thunderous glory at every hour of the day.

    A must stop and see while traveling along the Park Loop Rd in Acadia National Park. A ranger at the visitors center recommended we get there 2 hours before high tide to get the best waves. There were so many beautiful views to stop and take in, that we were too late by the time we arrived :-/ We did see a few bigger waves that made some thunder noises, but not as loud as we were hoping. It was still an awesome stop though. We stayed and just enjoyed the beautiful weather and sounds of crashing waves on the granite rocks! There is street parking available...seems like most people do this; however, there is a parking lot and gift shop right across the street. The gift shop is pretty small, but they still have plenty of souvenirs, snacks and beverages. I'd recommend trying the blueberry soda...yum!

    This was one of the cool sites that we viewed while exploring Acadia National Park. I'm glad that we stopped because it was a cool site to see and to also take photos. Even on a gloomy day it was a good spot to stop and take in the views. There isn't a parking lot for this stop so parking will be along the main road and it fills up fast. I'd recommend trying to take this in earlier in the day before the park gets busy. We parked along the road and the walk to the site wasn't too long. The path to the rocky viewing area was just a few steps and easy to maneuver. We waited out on the rocks with lots of other tourists and washed the waves rush in. It was a pretty spot to relax and just take in the beauty of the park.

    We stopped at Thunder Hole for a nice picnic lunch while hiking in Acadia National Park. Like so much of the park Thunder Hole is another example of nature's incredible and amazing beauty. This small inlet has been naturally carved out of the rocks and gets its name from the thunderous roar of the waves crashing into a little cavern at the end of the inlet and spewing high into the air. You can climb on the rocks and just have fun taking in the incredible views. There is parking and restrooms nearby as well as a small gift shop. You can drive up or hike the very scenic ocean path from Sand Beach. The hike is less than a mile and a half and is pretty gently so it won't wear you out. After taking in Thunder Hole you can continue on the trail for another 7 tenths of a mile to Otter Cliff. If you visit Acadia National Park make sure Thunder Hole is on your list of places to visit.

    We loved thunder hole! You do have to pay the park fee which is $30 (I think) to get in. Parking was a little confusing. Don't take the fret spot you see on the road! There will be more closer to a thunder hole. We walked about a mile because we took the first spot we saw. We enjoyed the walk there, though. But it was very pretty. We unfortunately didn't get to hear the thunder sound.... but we are also impatient and love to move and explore. We had a lot of fun climbing on the rocks and seeing the scenery. I loved watching the waves crash on the rocks. I enjoyed walking around and seeing the area. Would love to come back some time!

While it was once the 41-room summer cottage for the Bowdoin family today it serves as the headquarters of the the Bar Harbor Historical Society. The mansion is also a wedding venue. If, when visiting La Rochelle you are hoping to feel like you are stepping into a time machine to 1903, you'll need a lot of imagination. The mansion has been the home to various families and it has served several purposes since it was the Bowdoin's summer cottage. So, the physical structure is original but very little else is. Also, a lot of the rooms are closed and serve as private offices or storage for the Bar Harbor Historical Society. But, as a bonus, there is a lot of Bar Harbor history and artifacts displayed throughout. What I found most interesting about La Rochelle was the Flower Room including the placement of it. I can recall visiting mansions with a designated area of the kitchen or butler's pantry for assembling flower arrangements but I can't recall one that had a dedicated Flower Room. I also thought it was interesting that the Flower Room was placed adjacent to the main foyer instead of closer to where the servants would be working. La Rochelle is a wonderful piece of Bar Harbor and American history and I am grateful that the Bar Harbor Historical Society was able to purchase La Rochelle to preserve it for future generations. I also appreciate the very kind volunteers that work at the mansion. La Rochelle is am impressive site from West Street but it looks even more impressive from water, or so I imagine. We did not get to see the house from that view but based on pictures, you can really see the elevation of the home and the many chimneys. Before leaving La Rochelle we visited the gift shop which is full of pretty things. I was eyeing up some puzzles but due to very limited space in my suitcase I just purchased a few greeting cards. Overall we had a nice visit to La Rochelle and we were glad to support the Bar Harbor Historical Society.

Crazy people crowded the top deck and spent hours out in the cold...I wouldn't do that. The second deck is kind of stuffy and you have to watch mostly from inside. The first deck is where it's at. If you sit at the windows of the forward section on the Friendship V, there are not benches outside the windows as there are with the back half of the deck. So you get a nice clear view unless someone stands along the rail. Most of your time will be spent cruising. We were out for 3 1/2 hours. We probably spent 45 minutes actually watching whales and other animals. On the way to the boat we grabbed breakfast next door at the Sunrise Cafe to take on the ship and while the reviews were very good, the food and price weren't worth it and they are definitely charging tourist extortion prices. Either get up earlier and go somewhere else or eat at your hotel before hand. If you plan to ride on the top deck you will need to bring all kinds of warm weather clothing. Sitting inside while underway is the way to do it. I was in a t-shirt most of the day and would throw on a light zip up hoodie to go outside when they found a whale or something interesting. But the people who stayed outside had to bundle up quite a bit. It was 75 in Bar Harbor but 55 on the water and even colder when the ship was moving close to 30mph. It covered almost 80 miles during our voyage. By the end most of the people that ran, yes, they literally ran to the top to sit shoulder to shoulder with strangers...they all came inside. I don't think that would have been possible on a more crowded ship. The first thing they spotted was a pod of dolphins. Then the saddest thing happened. We came upon an injured juvenile humpback whale. He couldn't dive and had a huge injury and was practically dying before our eyes. All my life I have been waiting to see a humpback whale and when I finally did it was super sad. They found some fin whales later that kept diving and coming up in groups and that was cool to see. Definitely bring binoculars or rent them. They are $20 to rent and you must leave your ID with them so they know you'll return them at the end. We also got to see some remote lighthouses which had a bald eagle and some seals or walrus hanging out in the water...can't remember which species. You could barely see their shape since they were far away and their color was close to the rocks. I included a picture of the on board menu for snacks and drinks. They are quite reasonable. The bathrooms start off nice and clean and get progressively festival porta-potty like as the voyage progresses....I guess it's hard to not make a mess when the boat was rocking and rock it does! We didn't even have high seas or bad seas and it moves a ton. Bring dramamine or take it before you leave if you think you might need it. Lots of people throwing up on our trip and you can't escape the sound. You're welcome to bring snacks and drinks and I recommend it since you don't know how long you're going to be out. All in all it was a great trip and each one is like drawing cards. The trips after ours saw way better wildlife but you just never know what you're going to see so just take the chance and go. Completely worth it and very reasonably priced at around $90/adult.
