  • A beautiful place! The mosquitoes chased us off, but if we would have brought some OFF, we would have stayed for hours. Its beautiful, and the locals were nice and welcoming.
  • Clean, well-kept. Nicely mowed grass with a paved walking trail. Several historical markers throughout the island to detail the various Green River expeditions that have occurred over time. The path connects to a neat footbridge across the Green River and to the greater paved trail system in the town.
