    What a wonderful little way to get some energy out of the kids. Herkimer Diamond mine sounds like a ton of bull but I can tell you we had a blast. They give you a hammer and a few bags for your treasures, you keep what you find. After a short video on what your looking for it's off to the quarry! Herkimer diamonds are not actual diamonds, they are double terminated quartz crystals found inside exposed outcrops of dolomite in and around Herkimer County, New York. We found a few smaller ones, our friends little girl found a large one value at over $800, pretty cool. You can also make jewelry with your finds there. We had a blast and will be back! Ps wear safety glasses, bring gloves and avoid really hot days.

    fun! i found a bunch of these sized diamonds and a few larger, didnt have as much luck cracking them open as other people around me, these were found in the dirt or pre-exposed in the matrix. food & lodging on site would be super fun with kids i think!! great first rockhounding destination for anyone who's new to it!! also.. whoever was on aux today, the vibes were immaculate

    Sluicing.

    The staff here went above and beyond to be friendly and welcoming! The facilities were clean and easy to access. There was a lot of fun things to do for the entire family. The pool, and garden area was amazing! Every member of our party was able to relax and have a great time.

    Impressive! Friendly staff, clean cabins & bathrooms, grounds well cared for, excellent amenities. We stayed in a basic camping cabin. The bed mats are EXTREMELY hard even when doubled up with the 3 in topper I brought along. Also recommend a fan as the little cabins get hot! They have a unique natural tubing area (only a few feet deep) that curves around the resort. Can't forget the pool and my 5 year old loved the rentable all terrain pedal carts they had available. He had a lot of fun riding it down the grassy hills.

    Going into the mining area

    We took our 6 year old son and had a blast. We mined the entire afternoon and my son hung in the entire time. We found beautiful diamond totaling 200.00. Before we left we had the jeweler make our stones into a necklace and earrings. We will definitely be back. Also our cabin was located right next to the mine. It was small but perfect for us 3. It was also clean and the bathroom was nice.

    Wow! This place is a hidden gem! Stopped here for a couple nights before heading to the ADK. April went above and beyond to help us when we first arrived! She gave us a tour of the glamming pods- which we quickly upgraded to. She was so sweet and welcoming! She even let me niece pick the nightly movie. Tons of kid stuff, tubing down the river and a beautiful diamond shaped pool. Everyone at the resort and mine are so helpful! We found plenty of herkimer diamonds and had a wonderful stay!

    Herkimer gem mining

    Nice campground-beautiful grounds by the River. Lots of cabins; across the street from the Diamond mine, which was lots of fun. Ice cream and food trucks with many options. They provided a great outdoor concert on Saturday night, and the camp store and checkin staff were very friendly and helpful. Pets were welcome and walking the grounds was enjoyable. They are much more expensive than most KOAs, and still the mines cost extra.

    What a blast everybody in our family had so much fun here. My daughter is really into Gem mining and does a lot of sluicing. She could actually take hammers and chisels and break rocks open and find Herkimer diamonds she had a great time her and her brother jumped right in and everybody had a great time. Place is well organized, reasonable pricing. They have a room set up with a movie room on how to do the rock smashing and stay safe. Staff was real friendly and helpful I had a chance to check out their little Cantina for a cold drink and a bite to eat it'll do absolutely. Again this place was a blast look forward to another time.

    My family and I spend labor day weekend at the KOA. It was very pleasant and restful. I highly recommend this place. Professional staff, peaceful environment, good food. Fun times.

    The treehouse had a more comfortable bed than the cabin but the regular cabin was still very nice.

Earlier in the year gives you a longer opportunity to mine! $28 per person to enter. There is equipment to rent or buy, I suggest renting compared to the prices of buying, or bring your own! Compared to another mines, this one is smaller with three different areas, we chose the black diamond mine. Being newly excavated, we had a chance at unearthing more diamonds in this location versus cracking open the stones. Unfortunately, we stopped in during a mining competition so one mine was pretty much off-limits but we were still able to find a lot of cool diamonds and rocks

We went at a rough time with a brutal heat index but came back with a decent collection of stones. My son wandered and found a few stones loose in the dirt of the mine. Definitely suggest bringing a pop up canopy for shade while mining. The sluicing option (buy a bag, pour in sieve, rinse) produced some great stones and fossils that we can't wait to tumble and polish. Most of the lot is gravel, which makes for difficult terrain for wheelchair users. The beds in the cabin are rough sleeping, especially after a day spent mining. If you can, pack extra padding for a better sleep. Overall, a good experience. We'll be back when the temps aren't so cruel and see what we can get when we aren't risking heat exhaustion to pound rocks.

    From 10/9 and 10/10 2015…read more I came here to officiate my best friend's wedding at the Lake Chalet over the weekend, and I have to say- I'm very impressed by this place. First, this place is breathtaking, the lake itself is just amazing to look at with its blue-green color. There are acres of trails to walk, and because of the time of year it's so nice to be in nature. Secondly, the cabins are made of cedar, so they keep an okay amount of isolation in the cold, but these are not heated cabins so bundle up when you go to bed. The cabins are really nice on the outside as well as the inside; you do have to bring your own bedding for them considering this is a campground after all. Thirdly, there is a section here for RV's if you don't prefer pitching a tent or using the cabins. Also, they have a bunch of nice rooms in the hotel sections, which are neat, and spacious. Lastly, I was impressed with the staff here; they were super friendly and accommodating. I really appreciate their helpfulness, if I every get the chance to I would come back here because it's a pretty spectacular place

    Accomodating, Fantastic, Perfect are all words I usually reserve for Michelin-rated restaurants,…read morebut Lake Chalet went so above-and-beyond that there really are no words to describe my latest visit in over 25yrs As I stated in the opening sentence, it's been 25 years since I had last been to Lake Chalet, but that's due to life imposing it's will, and family circumstance. Living in Atlanta definitely has a lot to do with the gap in visiting, but in modern times, that's no real excuse. The reason for my latest visit was the death of my Mom. Her wishes were to be buried nearby in Utica, and that all of our family was to have a celebration of her life at The Chalet. Well, as anyone that deals with family knows, that often things go awry that make circumstances like a "funeral party" tough. The owners Mike and Christine went the extra ten miles to make sure our Mom's party went off without a hitch. There are no words of thanks enough to cover what they did for us in such a short amount of time. The property is spotless, well-thought-out and quaint, but perfect for a small outing with perfect backdrop. The lake is picturesque, and the camping spots are shaded with a very family-oriented feel to the overall property which make the perfect setting for our visit this go'round. Yeah, they can't control the weather, but whomever made the call to the man upstairs, made one helluva perfect scene for my Mother's life celebration. I'm sure that my only visits to Lake Chalet will involve visiting my Mom's burial site in Utica in the future, but it's nice to know that places like this exist. With people like Mike and Christine around, it's safe to say that anyone that visits here will be well taken care of in the best way possible. 10/10.
