Confirmed from Thielke Arboretum's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
Serene arboretum with a nature walk, ponds, playground and educational signs.

The Thielke Arboretum is a natural habitat with walking trails, pond views & a nearby playground. There's info cards along the nature walk & also an educational center providing programs. Donations & volunteers maintain the services. Large parking lot.
It is such a beautiful place with native plants and fauna. The trail is so relaxing. It seems very organized, and the people who work/volunteer here seem kind, knowledgeable, and loving what they do. A very nice lady gave us such a great intro and description of the arboretum, sharing as well a great bird ID app.
First of many visits today. What a beautiful place to get a good dose of nature. My daughter and I enjoyed every bit. Plenty of parking. Fun playground for the little ones. Not overcrowded. Decent walking trails. Not recommended for strollers. Cannot wait to visit again in a couple of weeks when everything is in bloom.
