opening hours
National Museum of Natural History is generally open daily from 10 am to 5:30 pm, and the current listing also shows extended Friday hours to 7:30 pm. The museum is closed on December 25. Check same-day hours before you go, because special events can change access.
tickets
General admission is free, and current guidance indicates that passes are not required for standard museum entry. TicketLens options here are mainly paid guided formats, including museum-only and combo tours. If your date is fixed, booking in advance improves start-time choice.

how to get there
The easiest Metro anchors are Federal Triangle, Archives-Navy Memorial-Penn Quarter, and Metro Center. From Federal Triangle, plan about 0.5 km (0.3 mi) on foot; from Metro Center, about 1.1 km (0.7 mi). For rideshare, use a Constitution Avenue drop-off to shorten your walk to screening.
accessibility
Accessible entrances and elevators are available across visitor areas, and free manual wheelchairs are offered first-come, first-served. Service animals and personal mobility devices are generally permitted. If standing for long periods is difficult, use quieter entry windows and ask staff for the smoothest route.
security
All visitors pass through security screening. Leave knives, aerosol sprays, glass containers, tripods, monopods, and selfie sticks outside to avoid delays at entry. Smoking and e-cigarettes are not allowed in museum spaces.
photography and filming
Personal photography and filming are generally allowed unless a specific gallery posts a restriction. Handheld use is the safe default, while tripods, monopods, and selfie sticks are not permitted. Commercial filming should be arranged separately in advance.
wifi
Free public Wi-Fi is available in many Smithsonian spaces via the SI-Visitor network. Signal quality can vary by hall, so keep tickets and maps available offline before you start your route.
luggage
There is no broad luggage-storage service for large travel bags, so bring only a compact day bag. Keeping gear light speeds up screening and makes movement between halls much easier.
