Free & Cheap Things to Do in Trenton

Museums

Four floors covering mastodons and dinosaur-era fossils, fine art, Native American archaeology, and New Jersey natural history — general admission free, donations welcome. The planetarium upstairs runs weekend shows on one of the state's best domes for $10 a head, kids half that.

Address: 205 W State St, Trenton, NJ 08608

Tip: Free parking on weekends in the lots beside the museum — the rare capital-city perk. Closed Mondays. The Hadrosaurus and mastodon skeletons are the kid magnets; time a planetarium show for the splurge.

Landmarks

Free hour-long guided tours of the second-oldest continuously used state capitol in America, freshly emerged from a top-to-bottom restoration — gilded dome, restored legislative chambers, and the lawmaking story told room by room. Public tours run on the hour, weekdays.

Address: 125 W State St, Trenton, NJ 08608

Tip: Reservations are required — call (609) 847-3150 ahead. Tour routes can shrink on Monday and Thursday legislative days; mid-week mornings get the fullest building. Pairs with the free State Museum two blocks away.

History

The 1758 French and Indian War barracks where Hessian soldiers were quartered when Washington stormed Trenton in 1776 — the only surviving barracks of its kind in the country. A major restoration wraps with a grand reopening on July 4, 2026, complete with living-history interpreters.

Address: 101 Barrack St, Trenton, NJ 08608

Tip: Time a visit for the reopening season — the July 4th celebration with a public reading of the Declaration is free, and the museum's costumed interpreters are among the best in the Mid-Atlantic. Confirm hours and pricing on the site before going.

Landmarks

A 148-foot granite triumphal column at Five Points, marking the high ground where American artillery commanded King and Queen Streets during the Battle of Trenton on December 26, 1776. Bronze reliefs around the base retell the Delaware crossing and the Hessian surrender.

Address: 348 N Warren St, Trenton, NJ 08618

Tip: The interior elevator to the observation deck no longer runs — this is an outside-viewing monument, best paired with the Old Barracks and State House on a walking loop of Revolutionary Trenton. The bronze panels reward a slow look.

History

The 1719 brick mansion of the city's namesake, William Trent, is Trenton's oldest building — a National Historic Landmark restored with period furnishings and an honest telling of the household's enslaved workers' lives. Guided visits run Wednesday through Sunday afternoons for $5.

Address: 15 Market St, Trenton, NJ 08611

Tip: Afternoons only, 1–4:30pm, closed Monday and Tuesday. The colonial kitchen garden out back is free to wander; allow about an hour for the house. Street parking is easy on weekends.

Parks & Nature

Frederick Law Olmsted's last great urban park — his only New Jersey commission — wraps 100 rolling acres around the 1848 Ellarslie Mansion, now the free Trenton City Museum of local art and the city's storied pottery industry. Deer paddock views, great lawns, and zero admission.

Address: 299 Parkside Ave, Trenton, NJ 08618

Tip: The museum keeps limited hours — typically Friday through Sunday afternoons — but the Olmsted landscape is open daily dawn to dusk. Trenton's Lenox and Boehm porcelain galleries upstairs surprise everyone.

Arts & Culture

Seward Johnson's 42-acre wonderland in neighboring Hamilton plants 270-plus contemporary sculptures among peacocks, lotus ponds, and bamboo groves — including his life-size tableaux of famous Impressionist paintings you can walk into. The $25 gate hides a genuine budget route.

Address: 80 Sculptors Way, Hamilton Township, NJ 08619

Tip: The $5 After 5PM last-Friday evenings (May through August) are the play — golden-hour light, four hours, full park access. Students always $12; timed tickets recommended on weekends.

Family & Kids

Mercer County's 267-acre working farm museum recreates New Jersey farm life circa 1900 — draft horses plowing, sheep shearing, maple sugaring, and hands-on Saturday programs where visitors actually join the chores. Admission and parking are free nearly every open day.

Address: 70 Woodens Ln, Hopewell Township, NJ 08530

Tip: Saturdays are the show — themed programs like old-time baseball, plowing matches, and wash day run 10am–4pm. Twenty minutes from Trenton up the scenic Delaware; check the Saturday calendar before you go.
