Outdoor in-person events have resumed. See event listings for outdoor and virtual events, and COVID-19 updates for current information about Arboretum operations.

Arboretum programs nurture the public’s interest in land care and living in harmony with nature. We offer many free guided nature walks and garden tours throughout the year and also welcome groups who are interested in tours on a range of topics. Explore our many opportunities below.

Free Nature Walks

Free Sunday nature walks take place every week at 1 p.m. and last one-and-a-half to two hours. Led by seasoned naturalists, these walks are a great way to learn about the land; plants, animals, and fungi; phenology; and ecological practices and concepts.

On the first Sunday of the month, April–October, we offer Garden Excursions, a gently paced one-hour stroll through the gardens to learn about the Arboretum. These tours are designed to be multi-generational learning experiences and are well suited for seniors.

Monthly night walks start before sunset and offer an opportunity to learn more about nocturnal nature. They are scheduled around the full moon and other astronomical events.

All of our free public walks are led by experienced naturalists. See the events calendar for listings.

Free Seasonal Birding Hikes

You can see more than 170 bird species at the Arboretum during the year. Join us for seasonal guided bird hikes in spring and fall. Bird hikes are free, but to help us plan please use this form to let us know you’re interested. See the events calendar for listings.
