Pelham is crossed by three New Hampshire state routes:
- NH 38 enters the town from the south at the Massachusetts border, and curves to the northeast, exiting the town into Salem. It follows Bridge Street through town, and serves as the commercial hub of Pelham.
- NH 111A begins at a junction with NH 128 just north of the Massachusetts border, going primarily northeast, exiting the town into Windham. It is known as Marsh Road and Windham Road within Pelham.
- NH 128 is part of the larger Mammoth Road which connects Lowell, Massachusetts to Hooksett, New Hampshire. It enters the town from Massachusetts border, and goes due north, along the western edge of the town, before exiting the town into Windham.

The park is located northwest of the center of Pelham at 305 Mammoth Road ( NH 128), just north of Nashua Road. The park's land area is surrounded by NH 128, two roads that branch off it, and a minor road which intersects NH 111A.
Muldoon Park offers many short walking trails, four variously sized baseball fields (ranging from t-ball to official), a soccer field, and a play area. Most of the trails lead to the park's two ponds, local roads and houses or to Beaver Brook, a small river. The town of Pelham completed an 18-hole disc golf course here, stretching over a quarter-mile, in September 2007. 
The Pelham Parks and Recreation department has recently added two non-official sized baseball fields to the southwest corner of the park. Construction is complete on one field with the exception of dugouts, and the other field is still under construction, as of September 2013.
There is now an 18-hole disc golf course at this park. Many players from surrounding towns enjoy a round of disc golf set in the woods adjacent to the sport fields.
