Discover a dense variety of ecological growth through the diverse, successional plant communities on site in this botany-focused tour and learn how this 35-acre site is carefully edited through an “addition by reduction” approach to working the wild gardens and grounds that share this post-industrial landscape. A series of iron-casted plaques, which include botanical illustrations of the local plant community, supplement the experience.

What to Know Before You Go

As a former industrial site, there are a few things to keep in mind to ensure an enjoyable visit.

  • What to wear: The majority of each tour is outside; please dress for the weather. Additionally, the ground is uneven—sensible shoes are a must. Sneakers or boots are recommended. Open-toed shoes and high heels are prohibited.
  • Restrooms & concessions: The rawness of the site is certainly part of its charm. However, that rawness also limits the creature comforts many of us are accustomed to, like running water. Portable bathrooms and wash stations are available. Food amenities are generally not available (with some exceptions, such as food trucks at festivals).
  • Photography: Photography is permitted. For safety reasons, videography and drones are prohibited.
  • Accessibility: Handicapped parking is available, but the grounds covered during tours are not wheelchair accessible.
  • Liability: By purchasing admission tickets, all visitors are required to sign a liability waiver and consent to be photographed (PDF).
  • Admission: Site access is limited to guided tours, workshops, and events. Unless otherwise noted, all admissions are ticketed.
  • Duration: Allow two hours for your tour.
  • Children: While kids of all ages are welcome, the tour content is recommended for children ages 8+.

Thank you for following these guidelines. We wish you to have the best visit possible and appreciate your patience as we continue to improve the visitor experience.
