Facility Overview

The Old Reservoir Parking lot serves as the dedicated trailhead and visitor parking area for the historic Old Reservoir—affectionately known by Lexington locals as the "Old Res." Situated at 451 Marrett Road (Massachusetts Route 2A) in Lexington, Massachusetts, this facility is a paved, open-air surface lot seamlessly integrated into the natural park setting. Because it is completely open-air without overhead clearance barriers, the lot easily accommodates standard passenger vehicles, family minivans, crossover SUVs, full-size pickup trucks, and vehicles carrying rooftop cargo boxes, kayaks, or bicycle racks. Dedicated parking stalls are striped on asphalt, offering straightforward access directly to the park grounds, swimming pond, bathhouse, and perimeter woodland paths.

Prime Location & Nearby Attractions

Located on the southern edge of historic Lexington, the parking area directly connects drivers with one of the town's most popular freshwater recreation facilities. Key local landmarks and destinations within immediate walking distance or a short drive include:

• Old Reservoir Beach & Park: Steps from the parking area, offering a freshwater swimming beach with seasonal lifeguards, picnic tables, shaded lawn areas, and family-friendly recreation facilities.
• Old Res Walking Trails: Direct immediate access to scenic woodland walking loops that circle the pond, popular with walkers, runners, and nature enthusiasts year-round.

Access, Navigation & Transit Connectivity

Access to the lot is straightforward via Marrett Road (Route 2A), an east-west arterial corridor connecting downtown Lexington with Route 128 / Interstate 95 to the west and Arlington/Belmont to the east. Drivers approaching from I-95 can take Exit 45 (Route 2A East) and reach the parking lot in roughly 3 minutes. The lot features a two-way driveway providing clean sightlines upon entry and exit, although caution is recommended during weekday morning and evening peak traffic along Marrett Road. For public transit users, MBTA Bus Route 62 and Route 76 operate stops along Marrett Road and nearby Massachusetts Avenue, providing scheduled bus service linking Lexington directly to the Alewife MBTA Red Line subway terminal in Cambridge.

Visitor & Driver Tips

On warm summer weekends and sunny holidays, the lot can reach peak capacity by midday due to the popularity of the municipal beach. Arriving early in the morning (before 10:30 AM) or later in the afternoon (after 3:00 PM) generally guarantees an open parking space without waiting. During the peak summer beach season, Lexington Recreation requires town beach tags or day passes for swimming privileges, though walking trails remain freely accessible. Finally, please observe town park regulations: park only during posted daylight hours (dawn to dusk) and avoid overnight parking to prevent ticketing or towing.
