This is the multi-mile warmer-weather stroll for when you’re done messing around—why, it’s practically a hike!

These four “ways” edge some of Boston’s most beautiful parks, including the Back Bay Fens and the Arnold Arboretum, and some of its most beautiful institutions, including the Museum of Fine Art and the Isabella Stewart Gardner Museum.

Start at Boylston Street and Fenway and end at Arborway and Blue Hill Avenue. Or vice versa.

The leafier, lusher run of the Charles River Esplanade—from about Berkeley Street in Back Bay to Charles River Dam Road in the West End—is the best part of it for strolling.

As the name implies, the esplanade hugs the Charles River and provides nonstop downtown views and a wee briskness this time of year.

If the 32-acre expanse shooting through Back Bay feels like a grand Parisian boulevard, that’s intentional—it was designed as such in the 19th century.

Memorials and statues dot the 1.3-mile run, which ends on its eastern terminus at the Public Garden.

Accessing the wrought-iron-fenced private area of Louisburg Square is probably not in the cards—unless you or someone you know owns one of the uber-expensive spreads surrounding it.

But it is free to stroll the perimeter and to take in the facades of the Greek revival townhouses lining the square.

From Louisburg Square, too, one can jump into the other delights that surrounding Beacon Hill has to offer (Acorn Street, anyone?)

The narrow, short street (it’s barely 250 feet long) in Beacon Hill is often called one of the most beautiful in America—and rightfully so.

Its cobblestone goodness recalls the 18th- and 19th-century buildup of Boston and looks achingly quaint pretty much year-round. Though, be warned: It can be crowded.

After strolling it, there’s plenty to check out in surrounding Beacon Hill.

America’s oldest public park dates from way, way back in 1634.

Its 50 acres are particularly inviting and scenic in the cooler months, with a number of statues, markers, and monuments for perusal—some less obvious than others—well as plenty of places to sit should the stroll prove taxing.

We suggest starting across Beacon Street from the Massachusetts State House and ambling your way diagonally down toward Boylston Street.

Pick any point along the 1.5-mile, 15-acre ribbon of parkland born of the Big Dig and you’ve got a prime spot for leisurely taking in the bulk of downtown Boston.

There is also a lot to see within the Greenway itself, including memorials, monuments, and fountains.

The HarborWalk isn’t so much a park as one big string of parkland and boardwalk—about 43 miles total, making it one of the longest linear parks in urban America (and one of the best waterfront parks in Boston).

Pick it up pretty much anywhere the city touches the coastline outside of Back Bay, Beacon Hill, and parts of Charlestown and East Boston.
