Stayed at Herkimer KOA in the Solar Kolony 1 cabin from 8/7/21 - 8/11/21 with my partner and 2 kids, ages 13 and 2. My In-Laws stayed at the Treehouse cabin from 8/8/21-8/11/21. I’ve stayed here before at Caesars Palace (the woof cabin) and the apple orchard, but years ago.||Obviously I like this place as I knew what I was in for. So this isn’t a glowing review of what there is, you can read that in the description. This is about what is not mentioned in the advertising.||My 13 y/o loves mining for crystals aka Herkimer Diamonds. So his activities were really just mining and then examining his finds. Mine is $14 pp and is open 9am-5pm with very little shade before 3pm. The 2 year old really just ran around picking the little white flowers that are weeds. We bought two tubes from the on-resort store ($30 each) and tubed the river, which was fun once you got the hang of it, which is to stay to the right and get off earlier than you expect.||I’m not a tent camper, have tried it and RVing, don’t love it, but this is very much like RV camping. The cabins are essentially trailers. Very compact. And its very mosquitoy outside as it’s in the woods, so… expect that.||Solar Kolony 1 says it sleeps 6 as there is a full size futon in the living area, a queen bed in the one bed room and twin bunk beds in the other. The twin beds are more narrow than an actual twin and the entire room are the built in bunks with 3 drawers under the lower bed with about 30 inches of floor clearance. The mattresses are plastic, they do provide a pillow, sheets and a thin blanket. We moved the mattress from the top bunk to our room and put it between the bed and the wall for the two year old, we brought pillows and blankets for him. 13 y/o hated the mattress so we wound up getting a blow up from Walmart and blowing it up in the floor space which meant he couldn’t close the door and had to use the bottom bed as his clothing storage. The queen bedroom did have storage (almost like built in kitchen cabinets) and the bed is accessible from either side. There is no way anyone should sleep on that futon.||The ventilation for the bunk room is a cut out in the wall near the ceiling, same for the queen room though that has a ceiling fan. So no noise privacy. There is an installed AC unit, but also a window unit right next to it. We bought two little fans from Walmart to move the air into the bunk room.||Paltry AC issues.||There is a small table with umbrella outside with 4 chairs and another two chairs with a side table. In the cabin is a table with 3 chairs and a coffee table in front of the futon. The TV in the main area didn’t work, we told them, they never came to fix it. The kitchenette is a good size for a compact kitchen. There is a mini fridge (no working freezer) and a 4 burner stovetop. Coffee maker. Toaster. No microwave.||The kitchen supplies are a mash of mis-matched glasses/cutlery and pots/one pan. They did give dish soap & sponge, paper towels & TP. they do have bbq tongs & spatula. The mini fridge means there has to be a cooler going for beer purposes. For a cabin that allegedly sleeps 6, the mini fridge and camping are not symbiotic.||At a couple of points some of our electric went out, not the AC though.||The bathroom has a shower stall and had a soap dispenser seemingly on the wall that had fallen and left a gooey mess in the stall. As there is no housecleaning service we just cleaned it up. Then the shower backed up and we cleared the clog ourselves. The towels provided are terrible and teeny. Bring your own.||The place was definitely cleaned between campers, but hasn’t been actually cleaned in a long while. The ceiling fans are caked in dust, as are the decorations and the baseboards are filthy. But this is more like camping then not. Paid WiFi ($12 for 3 days for 3 devices) was impossible to use in this cabin. Cabin is $219/per night.||My in-laws stayed at the treehouse, which says that it sleeps 4. The treehouse is the most novel cabin and featured in their cover page. It’s definitely cute. But it’s a small cabin sitting atop a hollow outdoor unlit room with a hammock in it. The queen sized bed is immediately there when you walk in and sits next to the kitchenette. There is a decorative trunk at the base of the bed where you would rest your bags. No storage at all in the unit. There is a table with two giant heavy wood chairs. A twin bunk bed built in to a ‘room’ but that’s the entire room with actual floor space of about 24” x48”. They used this as their closet. The furniture was all huge and designed to be novel, but my MIL literally couldn’t move a dining chair. Their mini fridge was missing a bunch of the racks and wire compartments that would render it useful. They had a microwave. This unit is teeny. No couch or sitting other than the bed or the two giant dining chairs. Outside is a table with 4 chairs and an additional two. Same mish-mosh of kitchen ware. Very very dusty decor, and lots of it (giant axe, deer head, guns, pot rack) Very dimly lit. Excellent source of exercise though as the staircase was pretty steep. The treehouse maybe soundproof- it’s close to the main road and the pavilion and they didn’t hear a thing, though they are almost 80. Cabin is $268/night.||The grounds are good, loads of goose droppings and mosquitoes. Sucks that the restaurant ‘the mining table’ is closed Monday-Wednesday and only open 4-9 Thur-Sunday. The pool is cold, the playgrounds are ok. The resort activities seem best aimed at the 4-10 year old range. The KOA is not responsible for the river despite their signage and the currant in the middle can be tricky. There were a lot of tent campers and RVs when we got there- very full. Which means noisy at night. We did not have garbage issues on the grounds or safety issues, and the 13 y/o walked freely.
