We stayed at Lyman Run because we needed electricity hookups, and Cherry Springs didn't offer it. Our trip was for astrophotography purposes, and Lyman Run is only a 10 minute drive away from the Cherry Springs viewing area. Totally worth it!
The good: Daggett Loop sites 16 and 17 are pretty solid. They're the last two in the loop and next to 17 is a river trail just to yourselves. It's nice. The bathrooms are modern and clean. Electricity hookups work great and I was able to pull a consistent 80% of max load(~32 amps) the entire time without issue. Sites are well kept. No cell service on site, but a 10 minute drive and you've got it (the best, imo)
The bad: The lake is a bit scummy/stagnant and was jammed pack with people (and since this review is written during COVID, no one was wearing masks or social distancing--disappointing). The sites are really close together with zero trees in-between sites. Bring your own privacy. PA has cross-county firewood ban, but the campsite doesn't have a firewood store. Had to drive 15 minutes off the campsite to find a random house selling firewood for $5 a bundle.
