    Dey Mansiom

    Documents that attest to General George Washington having used Dey Mansion as his headquarters can be found in the Library of Congress. There are 364 letters and orders totaling 594 pages that were written at the mansion., by and on behalf of Washington to army officers and the continental Congress. Washington stayed at the mansion from Saturday, July 1 until Saturday July 29, 1780., at that time he left to greet the French allies in Newport, Rhode Island returning to Dey Mansion Sunday, October 8 and staying till Monday, November 27, 1780. He then left for Morristown. Others who came to the mansion include: Alexander Hamilton, Nathaniel Greene, Anthony Wayne, and the Marquis de Lafayette. The Mansion is on both the New Jersey and National Register of Historical Places.. The mansion can be toured Wed-Fri from 1pm till 4 pm. Sat and Sun from 12 pm until 4 pm. It is closed Monday and Tuesday. Admission is $5 adults, $4 seniors and (3-17 yrs.) $3. Your admission cost gets you a professional pamphlet, a copy of a letter Alexander Hamilton sent to Elizabeth Schuyler, July 6, 1780 and a letter sent by George Washington. The tour starts in the kitchen and encompasses about 12 roped off rooms. Washington's bedroom and office are showcased. Original paint colors, some floor boards and a handful of original pieces belonging to the Georgian style home can be found. The window glass is a reproduction of glass from the period complete with waves and bubbles. Other artifacts while not original to the house are from the middle to later half of the 1700's. There are many interesting paintings as well from the 1800's.The gardens were designed by Fredrick Olmsted and his brother. Fredrick Olmsted is famous for his design of Central Park. Parking is free and an adjacent visitor center has just begun construction. Mainly for history enthusiasts this site has historical interest made richer by the narrative afforded by the docents..They have reenactments and a decorated Christmas Mansion tour as well.

    On this Oscar Sunday, my partner Ralph and I relived history in Passaic county, NJ only 15 mins away from our house. The Dey (pronounced Dye) Mansion is a superb example of Georgian architecture. This year they are celebrating its 240 year anniversary when General George Washington stayed here during the summer and fall of 1780. It served as a safe haven for the Continental Army offering shelter and abundant food. During the Revolution, Theunis Dey commanded the Bergen County Militia. While Washington resided here, he had many guests such as Marquis de Lafayette, General Anthony Wayne and Marquis de Chastelllux. It was during one of his stays at the house that Washington received news that the French allies had arrived in July of 1780. Later on that year, Washington returned to the mansion when he learned that Benedict Arnold betrayed the Americans. The Mansion sits on the 377 acre property of the Preakness Valley Park including a forge, plantation house, spring house, and a courtyard in the middle of the three buildings. General Richard Dey, Colonel Theunis Dey's eldest son, sold their homestead and 335 acres of land in 1801. From then on, various private owners possessed the mansion and surrounding acreage until January 10, 1930 when it was acquired by the Passaic County Park Commission. A full restoration of the mansion was completed in 2016 which most of the original wood frames and floors still exist. Admission is only $5 per person with a guided tour of the house and surroundings. Our guide for today was Kelly who was awesome by enlightening our knowledge. As an added feature not with the tour, one can visit the family's cemetery on the grounds of the surrounding golf course. If you are a Revolutionary War history buff, they have 2 re-enactments (July/October) during the year. This is your place!

    TEP deserves more than 5 stars for the amazing start to finish service we experienced on our 7 day…read moreadventure to Peru to hike the Inca Trail to Machu Picchu. From the time we signed up, to the time we boarded the plane to return home, TEP took care of every detail. We commented amongst ourselves that we felt like kids on vacation with our parents, as we didn't have to worry about any of the details - just show up and follow Neptali (our guide). From airport pickup in Cusco in luxury Mercedes vans where we were promptly served Coca tea to help with the altitude acclimation, to group dinners at amazing Peruvian restaurants, to historical tours and education on the history of the Inca - everything was covered and taken care of for us. And that was all before the amazing trek along the Inca Trail to Machu Picchu! Of course the trek itself was the highlight of the trip, and although it was extremely challenging for us, TEP's unbelievable attention to detail did not fail us on the trail. With nearly a 2:1 porter to trekker ration, our every need was met on the trail. We dined like kings every meal, and were consistently amazed with the quality (and nutritional appropriateness) of the food our chef and sous chef were able to put out with minimal kitchen conveniences. The thing I felt was most special about TEP's approach to this trip was the focus on gaining a cultural and historical appreciation for what we were experiencing. Every step along the way, we learned about the native people of Peru, the Inca civilization, the many ruins we came across, the vegetation we saw and how it was and is used, and the history of modern Peru. It was the trip of a lifetime, and have the help of The Explorer's Passage made it so much more enjoyable, and so much more memorable. The value of what they provide is amazing for the cost....rather, for the investment. I highly recommend them!

So much fascinating historical information that I can't wait to share with all my friends now; such a great group of fellow explorers; and all so perfectly run - well planned, perfectly on time, with a great variety of sights and insights for all types of travelers.

    Did you know that Lake Hopatcong is NJ's largest freshwater lake?…read more And did you also know that there's a great little place on the lake that lets you rent all sorts of strange inventions like a 'pedalboard' and a 'hydrobike' (along with the classics like kayaks and paddleboards) - so you can cruise along the lake, get a bit of exercise, fill those lungs with fresh air and more importantly... work up an appetite (so you can hit The Windlass right after)? I tell you it's true. All true. There were six of us (celebrating a birthday) - 5 on hydrobikes, 1 on a pedalboard. The lake is drop dead gorgeous and we went when it was still early and a bit overcast so it wasn't too crowded with boats and jet-skis and the like. (Waves/wakes from other boats can really dampen your own fun... so that stuff matters a bit.) But I gotta be honest: it was a lot of work. Unlike a kayak where you might get a nice 'bite' with your oar and can coast a bit... the bike is akin to being pneumatic (you stop pedaling and you almost immediately come to a halt as well). And those seats? They are not comfortable at all. Sore dupas all around (the following day as well, actually). But we all had a great time. The crew (Patty and Joe, I believe) were really cool, total professionals, and we always felt like we were safe as well having a great time exploring some of the lake and adjoining islands and whatnot. (We would definitely return in the future but would lean towards a kayak and not do the bikes again.) Wear sunblock, bring water, not sure if it was just me but my right foot was pretty soaked by the end whereas my left was dry (so you'd be better off wearing an old ratty pair of sneakers, regardless). Post-pedal was The Windlass (excellent) as well as some mini-golf (also excellent). Lots to do in this lovely part of Jersey. (But it'll cost ya!)

    A cousin of mine tried the hydrobikes and lived it, so I thought I would give it a try. I asked a…read morefriend to come with me and he said it looked like a pain in the ass. I made a reservation online. Patty was so friendly and made it a great time! She let me use some sun block and fill up my reusable cup at their water fountain. She told me that I would probably like the standup paddle board better because it had better maneuverability. I took her advice. It was a lot of excise and fun as we rode around and she told me about the history and pointed out different areas around the lake. We even picked up some trash from inside the lake and it made me happy to know that there are good people out there who are also passionate about the environment. It was hot and I "accidentally" fell in and got to enjoy the water a little bit. Patty also gave me restaurant and hiking recommendations around the area and even took a picture of me. You may be able to call and make a same day appointment, but online will only allow the following day. I don't think it's with bringing or risking losing your camera or phone out on the lake, there isn't anything really photo worthy.

Between the highways, farmlands, and beaches lies a series of historic mansions and modern palaces for guests to explore. Wealthy owners constructed many of NJ's castles during the Gilded Age. The late 19th century was a boom time for industrialists and capitalists, and it became fashionable to showcase one's wealth. Located on Garret Mountain overlooking the City of Paterson, this well-known landmark was once a private residence fashioned after an English castle, where my partner and I returned after undergoing 6 years of significant restoration work. Their website made it easy to book a reservation, ensuring reduced wait times, comfortable capacity management, and a smooth, welcoming visit for everyone. Built in 1892 and originally called Belle Vista, Lambert Castle was the domain of silk moguls Catholina and Isabella Lambert. It was constructed in the Medievel Revival architectural style out of local sandstone and granite. Lambert's fortune rose and fell with the silk industry, and he later auctioned off most of the works to pay his debts. Upon arrival at the visitor center, formerly the carriage house, we were greeted by the staff, where all guided tours begin, lasting 1 1/2 hours. Our guide was Mary Beth. She provided us wonderful information, pointed out small details like the door hinges or artwork, and answered our questions as a group of 19 patrons looked at each room much brighter. Unfortunately, photography is prohibited inside to preserve the interior for future visitors and make patrons appreciate what they were looking at. Lambert Castle serves as a physical time capsule that reflects the shifting fortunes, societal values, and architectural ambitions of the eras in which it was built and would be great for a visit.

The admission tickets are $10. Zak was a wonderful tour guide. He gave us the history of the castle owners. In 1892, the castle was built by Catholina Lambert (the owner of the Paterson Silk Mills for his wife). Please see my original review for the history. We were informed "Not to photograph any of the interior in order to preserve the interior for future visitors". Upon entering the castle, you will be required to put booties on over your shoes. This is in order to preserve the floors. The castle does have 3 levels along with an elevator. In the foyer overhead, you'll see a magnificent colorful rectangle shaped Tiffany light fixture. It extends approximately 2' Wide and 6' in length. The furnishings were very elegant, yet very homey. All the rooms are filled with stunning sculptures and artwork. Some of items were on loan from different places. For example: The beautiful Grandfather clocks really caught my eye. They were on loan from the Ringwood Manor. (The Ringwood Manor is presently being refurbished and will be reopening soon). Hope everyone gets a chance to see this beautifully refurbished castle. Lambert Castle has two levels of parking.
