What if your next hike came with the chance to spot birds you would never notice on an ordinary walk? Some trails are best explored slowly, especially when the surrounding habitat is protected and wildlife can move freely around you.
Across Indiana, nature preserves and sanctuary trails give bird lovers opportunities to wander through forests, wetlands, prairies, and other peaceful landscapes while watching for species overhead and along the trail.
The experience is less about rushing from one viewpoint to the next and more about paying attention to the small movements and sounds around you.
If you enjoy combining a quiet walk with the excitement of wildlife spotting, these trails are worth seeking out.
1. Mary Gray Bird Sanctuary
Few places in Indiana wear the title of bird sanctuary quite as earnestly as Mary Gray. Owned by the Indiana Audubon Society, this 700-acre property sits on the edge of the glacial till flatlands of east central Indiana, and it has been quietly doing important work for birds and birders alike for decades.
Over 150 species have been documented here, and the sanctuary is part of the Mississippi Flyway, making it a genuinely significant stopover for migrating birds.
Summer breeding birds include the Wood Thrush, Cerulean Warbler, Kentucky Warbler, Blue-winged Warbler, and Scarlet Tanager. Five owl species call this place home, including the Great Horned, Barred, and the small but captivating Saw-whet Owl.
A handicap-accessible birding blind lets visitors observe without disturbing the birds, which is a thoughtful touch you do not find everywhere.
Bird banding takes place year-round, and the public is welcome to watch on most Saturdays. The Wetland Trail follows a large creek through forest to seasonal wetland areas, while other named trails like Cardinal, Woodpecker, and Prairie each offer their own character.
Late summer brings a dedicated hummingbird celebration that draws visitors from across the region. The sanctuary runs entirely on donations, which makes every visit feel like a small act of support for something genuinely worth protecting.
2. Big Oaks National Wildlife Refuge
Big Oaks National Wildlife Refuge carries a backstory unlike almost any other birding destination in the country.
Spanning 50,000 acres across Jefferson, Jennings, and Ripley counties, it was established in 2000 on the former Jefferson Proving Ground, a World War II-era munitions testing facility.
That unusual history created a landscape left largely undisturbed for decades, and nature filled the silence with something extraordinary.
The refuge has been recognized as a Globally Important Bird Area, and it is easy to understand why. Over 200 bird species have been recorded here, and roughly 120 are known to nest on the property.
Big Oaks supports one of the world’s largest breeding populations of Henslow’s sparrows, with an estimated 500 or more pairs raising young in its sweeping grasslands. A resident pair of Bald Eagles nests near Old Timbers Lake, and Golden Eagles use the refuge as a wintering site.
Public access is limited to about 4,000 acres in the northeast section, and all visitors must complete a safety video and acknowledgment form before entering, a small step given what waits inside. Guided van tours run during the public use season, including specialized birding tours and wildflower hikes.
Wood Ducks, Red-headed Woodpeckers, Orchard Orioles, and Worm-eating Warblers are among the many species you might spot on a single morning visit.

3. Eagle Creek Park Ornithology Center
Right inside Indianapolis, just minutes from downtown, Eagle Creek Park holds one of the most accessible and genuinely exciting birding experiences in the state.
The Ornithology Center is the heart of it all, a building designed to connect visitors with the birds around them through indoor exhibits, an outdoor viewing platform, and active feeding stations that draw species like Red-breasted Nuthatch, Pine Siskin, and Purple Finch from fall through early spring.
More than 280 of Indiana’s 419 documented bird species have been recorded within the park, which is a number that surprises most first-time visitors. During migration, Bald Eagles, Double-crested Cormorants, loons, grebes, and up to 21 species of ducks move through the reservoir.
The park is both an Audubon Important Bird Area and a stop on the Indiana Birding Trail, giving it credentials that match its impressive species list.
The center is also home to Raptor Ambassadors, non-releasable birds of prey used in education programs. Weekly events like Falcon Fridays and Meet a Raptor make this a genuinely fun destination for families and solo birders alike.
The 2-mile Coffer Dam loop circles a dedicated bird sanctuary separated from the main reservoir, while the 0.3-mile Eagle Crest Trail offers accessible birding on a paved surface. It is the kind of place that makes urban nature feel like a real discovery.
Address: 6515 Delong Rd, Indianapolis, IN 46254
4. Nonie Werbe Krauss Nature Preserve, Fishers
Not far from the busy roads of Fishers, a quiet stretch of restored land hugs the edge of the White River and holds something rare, a native tallgrass meadow in a state where such ecosystems have almost entirely disappeared.
The Nonie Werbe Krauss Nature Preserve was once farmland, but patient restoration work by the Central Indiana Land Trust has brought it back to something closer to Indiana’s original landscape.
The transformation is ongoing, and each season reveals a little more of what this land used to be.
For birders, the mix of wooded floodplain, open prairie, and oak savanna creates exactly the kind of layered habitat that attracts a wide range of species. Rare finds here include the Hooded Warbler, Worm-eating Warbler, and the state-endangered Cerulean Warbler.
Catbirds, House Wrens, White-eyed Vireos, Northern Flickers, and Indigo Buntings are also regular visitors, making even a casual walk feel rewarding.
Spring wildflower displays add another reason to visit early in the season, and the preserve also supports a healthy butterfly population. Two miles of easy walking trails wind through both prairie and woodland, with some gentle hills and valleys along the way.
The trails are frequently used by a nearby school for outdoor education, which speaks to how welcoming and accessible this preserve really is. Parking is available behind Riverside Middle School after 4 p.m. on weekdays and anytime on weekends.
Address: Eller Rd and W 116th St, Fishers, IN 46038
5. Hathaway Preserve at Ross Run
There is something almost theatrical about Hathaway Preserve at Ross Run. The gorge opens up without much warning, and suddenly you are looking down at vertical limestone cliffs that rise up to 75 feet, carved by the slow retreat of glaciers thousands of years ago.
Ancient reef fossils are embedded in the exposed bedrock, and the sheer variety of micro-habitats packed into this 72-acre preserve makes it one of Indiana’s most geologically interesting natural areas.
Protected by ACRES Land Trust and designated as a State Dedicated Nature Preserve, the land was donated by the Hathaway family in honor of Dr. H. Russell Hathaway.
Spring brings snow trillium, Dutchman’s breeches, trout lily, and hepatica blooming across the forest floor. Mature oaks with trunks more than four feet across shade the trails, and a large meadow opens up the sky for birds that prefer open ground.
Red-bellied Woodpeckers, Red-eyed Vireos, Sedge Wrens, and Henslow’s Sparrows have all been spotted here. The meadow draws sparrows, kingbirds, and meadowlarks, while the dense woodland and riparian corridors attract a rotating cast of forest species throughout the year.
About 2 miles of trails form four interconnected loops, some running along the gorge rim with views of the creek below. Sections can be narrow and elevated, so sturdy footwear is a smart choice.
This place rarely feels crowded, which only adds to its appeal.

6. You Really Should See Clegg Memorial Garden
Harold and Ruth Clegg bought this hillside land in the late 1930s as a private country retreat, and when they opened it to the public in 1965 as a memorial to their son, they gave Lafayette something genuinely special.
Managed today by NICHES Land Trust, Clegg Memorial Garden is the kind of place locals tend to keep quietly to themselves.
It is described as a hidden gem and sits far off the beaten path, which is part of its enduring charm.
The elevation drops 100 feet from the hilltop to the creek, and the looping trails pass through four distinct ecosystems within a relatively short hike: oak woodland, gravel hill prairie, a riparian corridor along Wildcat Creek, and savanna.
The gravel hill prairie is considered a rare ecosystem in Indiana, and the wildflower displays shift with each season from spring woodland blooms to rich summer prairie color and brilliant fall foliage.
Bird watching is one of the most popular activities here, with songbirds, deer, and butterflies all making regular appearances in the garden. The trail system stretches over a mile with some hilly terrain and staircases built into the hillside.
Despite the varied terrain, the paths are designed to accommodate different abilities, and the garden has a reputation for being senior-friendly. A trail map is available on site to help visitors navigate the different loops and find the best spots to pause and listen.

7. Heinzerling Family Five Points Nature Preserve
Karl Heinzerling acquired this land in the 1920s, and nearly a century later his family’s decision to donate it to ACRES Land Trust has made it one of the more quietly meaningful conservation stories in northeast Indiana.
Located in Garrett within DeKalb County, the Five Points Nature Preserve spans 116 acres, with a 2025 expansion bringing the total to 178 acres.
What was once agricultural land has been carefully and deliberately returned to something wilder.
The transformation is visible everywhere you look. In 2021, nearly 40 acres were converted through tree plantings and the establishment of tallgrass prairie.
An earlier effort in 2012 restored 22 acres to wetland habitat, and additional tree plantings created shelter for the federally endangered Indiana Bat.
Black Creek meanders through the property before joining Little Cedar Creek, and its banks support a rich mix of white and red oak, blue ash, sugar maple, and black walnut.
The preserve’s combination of wetlands, bottomland forest, restored prairie, and riparian corridors naturally draws a wide variety of birdlife throughout the year. Spring wildflower displays add color to the wooded areas, and the shaded 0.7-mile loop trail along the creek offers a calm, unhurried walk.
Two small bridges cross the creek along the way, and the trail opens up beside the water after winding through dense canopy. It is a modest trail by distance, but the habitat quality makes every step worth taking.
Address: 6800 Co Rd 7A, Garrett, IN 46738
8. Are You Ready To Explore Meadowbrook Nature Preserve
Northwest of Valparaiso, tucked just off Meridian Road, Meadowbrook Nature Preserve carries a history that adds an interesting layer to every visit.
The Shirley Heinze Land Trust acquired this former Girl Scout camp in 2013, and since then a long-term reforestation project has been steadily converting old agricultural fields back into moraine forest.
The preserve sits within the Valparaiso moraine, a geological formation shaped by the last glaciation, and its terrain reflects that ancient origin in every slope and ravine.
Three small streams wind through deeply wooded gullies, and in April and May the steep slopes burst with wildflowers. The preserve spans over 300 acres and offers four miles of trails across six distinct paths, ranging from a flat perimeter loop to more varied terrain deeper in the woods.
A Story Walk along Trail 1 incorporates interpretive signs about the natural habitat, making it a thoughtful experience for curious visitors of any age.
Birding here is considered rewarding in every season. Migrating birds move through the preserve in significant numbers, and Saw-whet Owls are actively studied on the property, a detail that gives nighttime visits an extra dimension of interest.
The preserve also provides habitat for bats, adding to its biodiversity credentials. The Shirley Heinze Land Trust maintains its offices on the property, so there is always a sense of active, attentive stewardship over this land.
It is the kind of preserve that rewards return visits.
Address: 109 W 700 N, Valparaiso, IN 46385
9. Richardson Preserve, La Porte
Richardson Preserve has a slightly hidden quality even before you step onto the trail. The parking lot sits inside a residential subdivision off US 35 between La Porte and Michigan City, and if you did not know to look for it, you might never find it.
That low-key entrance is part of what keeps this place feeling genuinely undiscovered, even though it is a featured stop on the Indiana Birding Trail and one of the higher-quality forested preserves in Indiana’s coastal region.
The preserve was named for Flora Richardson, an influential early advocate for protecting the Indiana dunes. Acquisition was made possible through Bicentennial Nature Trust funds, and the Flora Richardson Foundation has maintained its undisturbed character ever since.
Over 100 bird species have been documented here, with notable breeding warblers including the Ovenbird, Hooded Warbler, Louisiana Waterthrush, and Yellow-breasted Chat. Both cuckoo species are regularly seen, along with Rose-breasted Grosbeaks, Veeries, and Baltimore Orioles.
Mid to late spring is the prime birding window, though summer through early fall also delivers solid sightings. The habitat includes upland and lowland wooded areas in various stages of succession, emergent wetlands filled with sedges and grasses, and at least two clear, cold, sand-bottom streams.
The 2.6-mile trail system uses hard-packed gravel with footbridges crossing through forested and wetland sections. Hawks, hummingbirds, owls, sparrows, and woodpeckers round out a species list that makes this preserve genuinely hard to leave.
Address: 5265 N Pawnee Trail, La Porte, IN 46350
