Riverway, Boston

If you glance at most Boston maps, you might be led to believe that the Riverway is just another busy road. But in reality, it's the complete opposite-a tranquil, meandering strip of nature's serenity. Part of Frederick Law Olmsted's brilliant creation known as the Emerald Necklace, the Riverway sprawls across 34 peaceful acres, stretching for just under a mile along the border of Boston and Brookline.

While cars zip by on the Boston side, on the other side of the Muddy River, there's a whole different world. Here, you'll find charming bridle and walking paths dating back to around 1890, gracefully nestled below street level. This place truly shines in the summertime when the lush canopy of majestic oaks acts like a natural shield, blocking out the clamor of traffic and the scorching sun. As you amble along, you'll occasionally pass beneath picturesque old stone bridges, and you'll spot inviting benches strategically placed for moments of relaxation and contemplation.

Note that the landscape and hills you see aren't exactly the result of Mother Nature's handiwork, but were designed and shaped to offer city residents a beautiful and healthful escape. Even the Muddy River isn't entirely natural; Olmsted had it dredged to create a winding stream that flows into the Charles River.

Technically, they've labeled the Brookline side of the path as a bikeway, while the Boston side is reserved for pedestrians. But here's a secret: the Brookline side, despite occasionally running alongside the Green Line tracks, tends to be quieter and offers better views of the river. So, for a round-trip adventure, set out on one side and return on the other, doubling your dose of Riverway serenity.
