Seasonal nature notes and what to look for now

  • 🌞Midsummer — early morning visits most comfortable; look for deer fawns in quieter clearings
  • Historic character is a year-round quality here — summer brings its own atmosphere to the setting
  • 🐕Dogs welcome — bring water in summer; the site has enough space to find shade on hot days

Good to know
