National Arboretum doesn't need savings math — the ticket line is free for everyone, every open day. The only costs left are the extras — special exhibitions, parking and food are where the day's budget actually goes.
United States National Arboretum doesn't need a calendar — general admission is free every day it's open, which changes how you plan compared with a free-day museum. There's no crowd spike to dodge and no reservation race. The date that matters here isn't an admission date at all: it's whichever ticketed special exhibition you might want to add, since those (the grounds and gardens, and the National Bonsai & Penjing Museum (closed on federal holidays from November through February). Restrooms and maps are in the Administration Building until 4:30 p.m., and at Arbor House until 5 p.m.) run on their own schedules and prices.
Regular tickets ($0 — always free) are on usna.usda.gov; buying direct means no reseller markup. Already a member somewhere else? Our reciprocity lookup checks whether that card covers admission here.
