Rock Meadow Conservation Area in Belmont, Massachusetts, is a 70-acre mix of meadow, wetlands, and woodland trails, offering a peaceful escape just outside Boston. It's especially popular for walking, trail running, birdwatching, and dog walking. The wide, flat paths make it family-friendly, and the open fields provide great opportunities for spotting butterflies and wildflowers in warmer months. The Western Greenway Trail runs through the area, connecting to nearby conservation lands. Biking is allowed on designated trails, though the terrain is best suited to casual or hybrid riding rather than technical mountain biking. Parking is available off Mill Street.

Lone Tree Hill Conservation Land in Belmont, Massachusetts (often called Lone Tree Conservation Area) offers a peaceful mix of forest, meadow, and historic carriage roads. Popular with walkers, runners, and dog owners, its wide trails wind through oak and pine woodlands and open fields with views toward Belmont Hill. Interpretive signs highlight the area’s history, including former estate grounds and stone walls. While biking is permitted on the main access roads, it’s limited—narrower trails are for foot traffic only. It's a great local spot for a quiet outing close to town, especially in fall when the foliage lights up.
