Visiting this summer

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
