Holtwood is an unincorporated community in Martic Township, Lancaster County, in the U.S. state of Pennsylvania. Holtwood is the site of the Muddy Run Pumped Storage Hydroelectric Power Plant (172 Bethesda Church Road West, Holtwood, PA 17532), along the Susquehanna River. It pumps water into a reservoir during off-peak hours and uses that water to generate electricity during peak demand hours; it produces over 1,000 megawatts (MW) of power.

The Holtwood Arboretum over 5,000 acres (20 km2), also known as Holtwood Preserve, is a recreation area, arboretum, and wildflower preserve located on New Village Road off Pennsylvania Route 372 in Lancaster County, Holtwood, Pennsylvania. It is open to the public daily without charge. The site is owned by PPL Corporation and provides public recreation, camping, hiking, picnicking, sightseeing, fishing, and hunting. The lower Susquehanna River runs through the preserve, which also contains substantial fish ladders (said to be the largest in the United States) and a museum of Native American artifacts.

Holtwood Dam (also Holtwood Hydroelectric Dam, Holtwood Hydroelectric Plant, McCalls Ferry Dam) is the oldest of three major dams built across the lower Susquehanna River, and the middle location of the three. It was constructed as the McCalls Ferry Dam between 1905 and 1910 by the Pennsylvania Water & Power (PW&P) Company. The dam was renamed Holtwood in honor of two company executives. PW&P merged with Pennsylvania Power & Light (PPL) in 1955. In 2015 Talen Energy took over PPL's generation and immediately sold the Holtwood plant to Brookfield Renewable Energy Partners to comply with federal antitrust requirements.

The Conestoga Trail System is a 65.8-mile (105.9 km) linear hiking trail in Lancaster County, Pennsylvania. The system connects several relatively short and discontinuous footpaths with walks on paved roads. About 53% of the network's distance is made up of road walking, and those segments are intended to showcase the rural scenery of Lancaster County, utilizing three covered bridges and passing numerous Amish and Mennonite farms, as well as some urban and suburban neighborhoods in and around Lancaster. The footpath segments offer wilderness scenery of the type that can be found in many of Pennsylvania's forested areas, plus some walks alongside farm fields.Most of the off-road portions of the route are on private property, so except for several miles near the south end of the route, camping is prohibited along most of the Conestoga Trail System. The trail route is maintained by Lancaster Hiking Club, which regularly searches for options to relocate the route off of roads and into private or public woods and fields, so the route and distance of the Conestoga Trail System are known to change periodically.
