Over 150 resident and migratory birds have been spotted in Mianus River Park and around 70 recorded as breeding in the park. Heron and kingfishers may be seen along the river, and woodpeckers and warblers are amongst many other species seen in the park. Friends of Mianus River Park and Audubon Greenwich have created an "urban oasis" in the park with native, bird-friendly plants as a safe haven for migrating birds.

Why not print a copy of our list of birds and record how many types of birds you can spot? The list is downloadable on our Nature and Wildlife page.


Around 15 different mammals have been recorded in the park, ranging from white tailed deer to white-footed mice. Many are shy and can most easily be seen early in the morning or later in the day, especially away from the busiest sections of the park. Check out our list of mammals downloadable on our Nature and Wildlife page.

In addition, the park is home to frogs, salamanders, butterflies, and turtles, including some very large ones. The Gray Tree Frog, Pickerel Frog, Wood Frog, American Bullfrog, Spring Peeper, and American Toad have been recorded in the park, and Spotted Salamanders, Red-backed Salamanders, and Eastern Newts are also park residents.

Cross Country Skiing

With many miles of easy trails, Mianus River Park is a great location for cross country skiing, but skiers should get out early as fresh snow attracts many park users. A trail map can be downloaded at our trail map page.

Dog Walking

Mianus River Park is a popular destination for dog-walkers. A trail map can be downloaded at our trail map page. Dogs must be on leash at all times.


The Connecticut DEEP stocks the Mianus River each spring and fall with thousands of trout. The Mianus River is an extremely popular river for fishing due to the easy access and deep pools through the park.

For fly anglers, the Mianus River is renowned for its "early black stonefly" hatch which typically takes place on warm, bright days in late March. During this early time of spring, aquatic insects hatch from the river and fly into the trees to mate. When the females return to the water to lay their eggs, the trout are waiting and will readily hit the dark flies skittering across the water's surface.

Fishing Regulations: Fishing is allowed year-round in Mianus River Park, with the following regulations. From September 1 through the third Saturday in April fishing is catch and release only - meaning all trout caught must be immediately released into the river unharmed. During this time period, anglers are not allowed to use bait (worms, meal worms, minnows, PowerBait etc...) and can only fish with artificial flies or lures with a single hook - no treble hooks allowed. From the third Saturday in April until August 31, anglers may use bait as well as artificial flies and lures and are allowed to keep a maximum of two trout per day.

A great way to learn more about fishing the Mianus River is by joining the Mianus Chapter of Trout Unlimited, a local conservation organization made up of more than 600 anglers who work to protect and restore the rivers of lower Fairfield County. You can learn more and see a list of coming events online at www.mianustu.org


Geocaching (an international treasure hunting game) is active in the park. There are 10 caches in the park. A map showing the general location of the caches is availabe on the Geocaching site.

If you go to the map and hover over a cache it will bring up general information about the cache. Follow the links for more detailed information about the cache. Geocaching requires a gps device. A real gps or even a phone will work but finding a cache directly from the map is not practical. There are smartphone apps designed for geocaching.

For more information on Geocaching and how to participate, go to www.geocaching.com


Mianus River Park has varied and interesting geology including glacial erratics and moraines. Check out our geology section to learn more.

What is Letterboxing? Participants seek out hidden letterboxes by following clues that are posted on the Internet. Curious? Visit www.letterboxing.org to find out if there are any in the park.

Mountain Biking

Mianus River Park is a popular location for mountain bikers. There's a good variety of scenery from trails that skirt the edge of the river to winding ascents past all shapes and sizes of rock outcroppings. The diversity of easy to challenging trails linked by several interconnected loops keep it a fun place to ride; although mountain biking is allowed only in certain sections of the park. On Mondays (depending on the weather), FCNEMBA leads group rides. Check out their site for further info >

Nature Trail

Nature Trail

Friends of Mianus River Park have created a Nature Trail in the park with 13 points of interest. The Nature Trail is about two and a half miles long and takes no more than two hours at a leisurely place. The trail is marked with green blazes painted on trees along the way. The thirteen points of interest are marked by numbered green posts, covering a variety of features in limited detail.
