Poor communication, rich in ticks
We were really looking forward to this trip, but unfortunately the conditions at the Alder site were so poor that we decided to stay the night at a hotel rather than endure what was shaping up to be a miserable night of camping.
Some of the problems could have simply been solved by better communication and expectation setting. For instance, what was described as an easy and pleasant hike was actually a slog through marshy and uneven terrain, and the provided wagons were wholly inadequate for hauling our tent, firewood, and supplies over the fallen trees and standing water we encountered. Had the description for this site included information about these obstacles, we could have better prepared to deal with them.
However, some problems at the site were not simply a matter of poor expectation setting. Allowing tall grass and brush to grow over the trail is irresponsible in deer tick territory, and I doubt even the most seasoned campers will enjoy a good night's sleep with ticks crawling all over them and their gear.
Outside of the Alder site, most of Camp Amnicon seems pleasant and well-maintained. The view of Superior is beautiful, but the beach isn't great for swimming if that's your primary aim. Incidentally, the camp seems to be maintained by some sort of Christian group judging by the chi-rho symbol adorning many of the facilities, which didn't bother us but also wasn't really communicated in the Hipcamp listing.
