From Lexington, take Route 2A west from Massachusetts Ave. (Route 4/225) at the National Heritage Museum; follow the BATTLE ROAD signs. From Boston and Cambridge, take Route 2 into Lincoln and stay in the right lane. Where the main road makes a sharp left, go straight onto Cambridge Turnpike. Signs that point to HISTORIC CONCORD lead downtown. To go straight to Walden Pond, stay in the left lane on Route 2, take the main road (Route 2/2A) another mile or so, and turn left onto Route 126. There's parking throughout town and at the attractions.
The commuter rail (tel. 617/222-3200; www.mbta.com) takes about 45 minutes from North Station in Boston, with a stop at Porter Square in Cambridge. The round-trip fare is $13. There is no bus service from Boston to Concord, and no public transportation between Lexington and Concord. The Liberty Ride tour operates in the summer and fall.
The Concord Chamber of Commerce, 15 Walden St., Ste. 7, Concord, MA 01742 (tel. 978/369-3120; www.concordchamberofcommerce.org), maintains a visitor center at 58 Main St., next to Middlesex Savings Bank, 1 block south of Monument Square.

Ninety-minute guided walking tours ($20 adults, $12 seniors and students 13-18, $5 children 6-12, free for children under 6, $45 family [two adults, two kids]) are available Friday through Monday from mid-April through October.

The town website, www.concordma.gov, has an area with visitor information.
The train station is about three-quarters of a mile over flat terrain from the town center. Concord is relatively compact; if you plan to concentrate on attractions near downtown, the commuter rail and your feet will get you there. If you plan to visit more than a couple of destinations, or if you can't miss the Old Manse, the North Bridge, or Walden Pond, seriously consider driving.
