Radnor Lake State Park

Radnor Lake is where Nashville goes to breathe, and it is remarkable that something this wild sits inside the city limits. The park covers just over 1,400 acres of wooded ridges and hollows in the Oak Hill area south of downtown, wrapped around an 85-acre lake that was originally built as a railroad reservoir in the early twentieth century. It was saved from development in the 1970s by a citizen campaign and became Tennessee's first State Natural Area, which explains the strict rules and the hushed atmosphere: this is a place for walking, watching and photographing wildlife, not for picnics, dogs on the main trails or bikes. There are about 7.75 miles of trails. The classic route is the loop around the lake — the shaded South Lake Trail on one side and the paved Otter Creek Road Trail on the other — which takes an hour or so at an easy pace and is the best chance to see great blue herons, turtles, wood ducks, deer and, if you are lucky, otters or owls. The ridge trails climb steeply above the lake and reward fitter hikers with quiet and fall color. The park weathered a severe ice storm in early 2026 that brought down hundreds of trees, and volunteers helped it reopen in March, two months ahead of schedule; repairs to Otter Creek Road and the south-shore trails were completed in late 2025. Fit: couples and anyone who needs a morning in nature, first-time visitors wanting to see a quieter side of Nashville, and families with kids who can walk a couple of miles. Even a short visit — a walk along the dam and a few minutes on a boardwalk — feels a world away from the city, which is exactly why locals love it.

The rules matter, so know them before you go. Radnor is open from 6am until twenty minutes after sunset every day of the year and is day-use only. Pets, jogging and bicycles are allowed only on the paved Otter Creek Road Trail; the rest of the trail network is for walking only, and visitors are asked to keep their voices down so as not to disturb the wildlife. There is no food service and no picnicking, so bring water and eat elsewhere.

How to do it well: arrive early — the two parking lots fill fast on weekend mornings and fine evenings, and cars back up on Otter Creek Road waiting for spaces. The west lot off Granny White Pike has the Walter Criley Visitor Center, with exhibits, restrooms and a gift shop, and is the best starting point for first-timers; the east lot off Franklin Road is smaller. You cannot drive between them. Walk the lake loop from the visitor center, and pause on the dam and the boardwalks for wildlife. Early morning and the last hour before sunset are the best times for animals and for light on the water.

Practicals and fit: the park is about fifteen minutes south of downtown by car; there is no practical public transit. Wear proper shoes on the ridge trails, which are steep and rooty. Spring wildflowers and fall color are spectacular, and winter brings clearer views through the trees. Pair it with lunch in 12 South or Green Hills, or with an afternoon at Belmont Mansion. Remember there is no food or drink sold in the park, so pack water, especially in summer. Photographers should bring a longer lens for the herons and turtles, and everyone should keep a respectful distance from wildlife.
