About Nichols Arboretum
What to See & Do
Peony Garden
Sitting on a south-facing slope near the main entrance, this is the largest collection of heirloom herbaceous peonies in North America. Close to 800 plants represent roughly 270 cultivars. Most are pre-1950 varieties. You won't find them at a garden center. Peak bloom runs late May through mid-June. The scent gets almost overwhelming on warm afternoons, somewhere between rose and vanilla with a peppery edge. Bring a camera. Rows of magenta, blush, and cream-colored blooms photograph beautifully against the green hillside.
Dow Prairie
Locals swear by this restored tallgrass prairie for late-summer visits, when big bluestem and Indian grass tower over your head and the goldenrod turns whole sections electric yellow. It's a working ecological restoration. You'll see seasonal burn marks in spring (slightly jarring at first), then notice the explosion of wildflowers that follows. Monarch butterflies tend to cluster here in August on their southward migration.
Geddes Hill and the Main Valley
The grassy bowl that opens up below Geddes Avenue is the Arb's social heart. Students sled here on cafeteria trays in winter, slackliners string up between oak trees in summer, and on warm evenings you'll find clusters of people sprawled on blankets watching the light fade. The hill is steep. It'll work your calves. Runners use it for repeats, and you'll likely pass a few on the way up.
Huron River Frontage
The Arb's northern boundary runs along the Huron for nearly a mile. The flat riverside path stays popular for slow walks. You'll often spot great blue herons standing motionless in the shallows and turtles lined up on fallen logs. Come at golden hour. The water turns copper-colored. The cottonwoods on the far bank rustle audibly even in light wind.
Centennial Shrub Collection
Underrated next to the Peony Garden. Still worth the detour. This collection winds through a quieter section near the Washington Heights entrance. The viburnums and witch hazels put on a quiet show in early spring before anything else has leafed out. The witch hazel blooms smell faintly of citrus and clove on a sunny February day. That's the kind of small surprise that makes the Arb worth returning to in every season.
Practical Information
Opening Hours
Open daily, sunrise to sunset, all 365 days a year. No gates. No closing time enforced. After dark the trails get dark since there's almost no lighting, so most visitors clear out within an hour of sunset.
Tickets & Pricing
Free admission, always. Nichols Arboretum is part of the University of Michigan and runs as a public greenspace at no cost. Donations support the gardens. They're budget-friendly to drop in the box at the visitor information kiosk near the Washington Heights entrance. Guided tours during peony bloom are also free, though donations are welcomed.
Best Time to Visit
Late May through mid-June nails peak peony bloom. That's also when the Arb is busiest. Weekends during bloom can feel crowded near the garden, though the woodland trails stay quiet. October brings excellent fall color. Geddes Hill is the spot. The sugar maples turn that almost-unreal orange. Winter has its own appeal if you don't mind cold. The bare structure of the landscape reveals itself, and fresh snow on the prairie is striking. The worst time? Mid-summer afternoons in July, when humidity makes the ravines feel swampy and the mosquitoes get serious near the river.
Suggested Duration
Plan on 90 minutes to two hours for a decent loop. It should hit the main features. Add another hour if you're a slow walker, a photographer, or visiting during peony season when you'll want to linger. Trail runners can cover the whole property in 30-40 minutes. Birders are different. They've been known to spend entire mornings on a single section.
Getting There
Things to Do Nearby
The Arb's sister property sits a few miles east near US-23. Worth pairing. Matthaei has the conservatory and formal gardens that Nichols deliberately skips: tropical greenhouse, bonsai collection, manicured display beds. Together they cover the full range of what U-M's plant programs do.
About a 20-minute walk west from the Arb's main entrance. This historic district has the Saturday farmers market (running since 1919), Zingerman's Delicatessen, and a cluster of independent shops. Pair an early Arb walk with a late-morning market browse, then a sandwich from Zingerman's. Worth the line.
Downstream from the Arb along the same river, Gallup rents canoes and kayaks in warm months. It also has a flat paved path that connects most of Ann Arbor's riverside greenspace. Worth a visit. Go if the Arb leaves you wanting more water and less hill-climbing.
A 10-minute walk from the Arb's south entrance, UMMA is free. The collection is strong, ranging from Asian ceramics to contemporary American painting. Pairs well with the Arb. Both are quiet, free, and reward an unhurried hour.
Technically inside the Arb but easy to miss. It's a small interpretive space near the Washington Heights entrance with seasonal exhibits, trail maps, and friendly volunteers who tend to know what's blooming. Stop in first. Do this on your initial visit if you want context before wandering.
