Upper Missouri River Breaks National MonumentThe Breaks
Entry is free — the cost is fuel and time: drive the gravel Back Country Byway only in dry weather, or float the 149-mile Wild and Scenic river from Fort Benton with a shuttle booked ahead; skip it entirely when rain is forecast, because the dirt roads turn to impassable gumbo.

- North America ↗Crossing between the US, Canada and Mexico by land needs your passport even on a day trip; rental cars need the company's written permission to cross, and most US and Canadian rental insurance stops at the Mexican border.
- North America ↗Cannabis is legal in Canada and in many US states, but taking any amount across the US, Canadian or Mexican border is a federal crime — including edibles and vapes.
- North America ↗The busiest US and Canadian national parks need timed-entry, campsite or lodge reservations in summer; release dates are months ahead.
- United States ↗Check whether you need an ESTA (Visa Waiver Program) or a visa on the official CBP and State Department sites; apply only through esta.cbp.dhs.gov, not third-party sites, and allow time before you book.
- United States ↗Several popular national parks use timed-entry or vehicle reservations in peak season; check each park's page on nps.gov and book on recreation.gov before fixing your dates.
- United States ↗Medical care is very expensive for visitors; buy travel insurance with high medical cover before you fly.
- United States ↗Tipping is expected: about 15–20% at sit-down restaurants and bars, and a tip for taxis, hotel staff and guides.
- Rocky Mountains ↗Trailheads sit above 2,400 m; give the first day to the altitude, not to a summit.
- Rocky Mountains ↗I-70 west of Denver and other high passes close for snow and for avalanche control; check the state road site the morning you drive.
- Montana ↗A rental car is effectively required; public transport between towns is limited to a few intercity bus lines.
- Montana ↗Mountain passes can close in winter; carry water, food and a blanket, and expect patchy cell coverage.

The Upper Missouri River Breaks National Monument protects the Missouri Breaks of central Montana, a badlands-and-prairie country of steep bluffs, cottonwood bottoms and grassy bench land that Lewis and Clark paddled through in 1805. The Bureau of Land Management manages about 495,502 acres (roughly 2,005 km²) along 149 miles of the Upper Missouri, designated a National Wild and Scenic River in 1976 and proclaimed a national monument in 2001. There is no entrance fee and no maintained trail network: the two ways in are the gravel Missouri Breaks National Back Country Byway, which is impassable when wet, and the river itself, floated from developed launch points at Coal Banks Landing, Judith Landing and James Kipp Recreation Area with a shuttle arranged in Fort Benton.

Time out
Finding the local time zone…
Times are local to the spot (zone loading). The half-hour margin is our rule of thumb, not an official figure; light fades earlier in forest or under cloud. Carry a headlamp on any route that could run late.
Accessibility
- The Missouri Breaks Interpretive Center in Fort Benton is on paved roads with accessible exhibits.
- The byway and river corridor are gravel, dirt and water only; not suitable for limited mobility.
Visiting lightly
- Pack out everything; there are no bins along the byway or river.
- Use developed launch and camp sites rather than informal pull-offs on private land.
- Keep your distance from wildlife and never feed animals along the river.
Questions people ask
How much does it cost to enter Upper Missouri River Breaks National Monument?
Nothing. There is no entrance fee and no permit for day use; the America the Beautiful pass is not needed. Your real costs are fuel, a river shuttle (about US$150–350 per vehicle, 2026 estimate) and boat rental if you float.
What are the best hikes in Upper Missouri River Breaks National Monument?
There are no maintained hiking trails — this is a drive-and-float monument. The best walking is short explorations from the river camps and launch points, or cross-country on BLM land with a map and navigation skills. The signature routes are the 47-mile Coal Banks to Judith Landing float and the gravel Back Country Byway drive.
When is the best time to visit Upper Missouri River Breaks National Monument?
May, June and September. Days are warm, the prairie is green in spring, and the roads are most likely to be dry. July and August are hot with little shade, and any month can be spoiled by rain that turns the dirt roads to gumbo.
Do I need a permit to float the river?
No permit is required, but you must plan your put-in and take-out in advance, arrange a shuttle, and register your trip plan with the BLM. Public access is limited to developed launch sites such as Coal Banks Landing and Judith Landing.
Can I drive the Back Country Byway in a normal car?
In dry weather, high-clearance vehicles handle most of it, but the roads are gravel and unsurfaced and become impassable when wet. Do not attempt it if rain is forecast, and carry fuel, water and a paper map — there is no cell service.
Where should I stay near the monument?
Fort Benton has the most lodging and is the best base, with the interpretive center in town. Loma, Virgelle, Big Sandy and Malta have small-town options, and there are developed campgrounds at Coal Banks Landing, Judith Landing and James Kipp Recreation Area.
