Overview
The Continental Divide runs through the western portion of the Helena-Lewis and Clark National Forest in a section that is reasonably accessible from Helena but rarely crowded. The CDT here follows the actual divide ridgeline through terrain that is more open than the forested sections common elsewhere in the range, providing the kind of panoramic views that are the CDT's signature experience in Montana.
The route described here is a 10-mile out-and-back on the CDT from a trailhead west of Helena, gaining 1,500 feet to the divide ridgeline and then following it north toward the Scapegoat Wilderness boundary. The terrain combines forested approach slopes with open ridgeline walking two phases of experience in a single route.
The proximity to the Bob Marshall Wilderness Complex sets the northern horizon. On clear days, the outline of the Chinese Wall, the Bob Marshall's iconic limestone escarpment, is visible 30-40 miles to the north from the divide ridgeline. This is the kind of view that contextualizes the scale of this wilderness complex and why it matters.
Grizzly bears are active in this section of the forest, particularly as the route approaches the Scapegoat Wilderness boundary. Bear spray is a genuine safety measure here, not a precautionary formality.
The Route
Miles 0 to 3: Trailhead to Divide Approach
From the trailhead, the CDT climbs through mixed conifer forest toward the divide. The first three miles gain approximately 1,000 feet through a combination of forested switchbacks and open meadow sections. CDT posts mark the route; GPS is a useful supplement. By mile 2.5, the forest begins to thin and the open divide terrain becomes visible above.
Miles 3 to 5: Divide Ridgeline
Above treeline, the trail follows the divide ridgeline northward through open tundra and rocky terrain. This section provides the route's best views east across the Helena Valley, west into the drainage systems approaching the Scapegoat Wilderness. The highest point of the route at approximately mile 4.5 offers the broadest panorama. Turnaround at mile 5 unless conditions and energy support continuing farther north on the CDT.
When to Visit
July through September is the reliable window. The divide ridgeline can hold snow into early July. September is excellent for clear views and quiet conditions. Check current conditions before your trip using the conditions-checking guide.
Afternoon thunderstorms are common on the exposed ridgeline in July and August. Plan to be below treeline by early afternoon.
What to Bring
Many hikers carry the following for this CDT section:
- 3 liters of water (limited sources on the open ridge; carry adequate water from the start)
- Bear spray, immediately accessible
- Full rain and wind gear for the exposed ridgeline
- GPS with CDT track downloaded; navigation markers can be sparse
- Topo map as backup
- Extra layers; the divide is significantly cooler than the valley
Individual needs vary. The exposed ridgeline demands more weather preparation than sheltered forest trails.
Practical Details
No permit is required for day hiking as of 2026. Dispersed camping is permitted in the national forest. Fires may be restricted during dry conditions. Follow Leave No Trace principles. For more on how national forests differ from national parks in access and rules, see our national forest vs. national park guide.
The America the Beautiful pass and veteran variants apply to developed sites. See our veteran benefits guide for fee programs that apply to national forest recreation.
Getting There
From Helena, drive west on US-12 to Lincoln, Montana (approximately 65 miles), then take forest roads south to the CDT trailhead. Alternatively, some CDT access points are reachable from I-15 north of Helena via forest roads east of the divide. The Helena Ranger District and Lincoln Ranger District can provide specific road numbers and current conditions. From Helena, allow approximately 90 minutes to 2 hours to the trailhead depending on the specific access route.
