At a Glance

  • Panoramic views over the Bighorn Basin and toward Yellowstone to the west
  • High elevation gain in a compact distance
  • Lower-elevation access point compared to most Shoshone high-country trails
  • Rattlesnake Mountain, a prominent landmark visible from Cody

Overview

Rattlesnake Mountain is a prominent ridgeline east of the Absaroka Range, rising abruptly from the Bighorn Basin floor to a summit area that provides an unusually wide panorama. The trail to reach it is brief but direct: 2,400 feet of gain over three miles, making this one of the steeper approaches in the Shoshone National Forest relative to its total distance.

The name may give pause, but the trail is named for the landscape character rather than any unusually dangerous snake population. Prairie rattlesnakes are present in the lower sagebrush sections, as they are throughout the Bighorn Basin look where you step on rocky terrain and avoid blind hand placements in brush. The vast majority of hikers complete this trail without any snake encounter.

What makes this route worth the effort is the view from the top. Rattlesnake Mountain sits at the transition zone between the Bighorn Basin desert to the east and the forested Absaroka mountains to the west, and the summit provides a clear line of sight in both directions. Cody is visible in the valley below; the Beartooth Plateau extends to the north; Yellowstone's thermal smoke is sometimes visible to the west on still mornings.

The Route

Miles 0 to 1.5: Sagebrush and Lower Slopes

The trail begins in open sagebrush country at the base of the mountain. This lower section is fully exposed to sun and is warm in summer months an early morning start is genuinely helpful here. The grade is steep from the first quarter-mile, with consistent climbing through sagebrush and grasses. By mile 1, the vegetation transitions to juniper and pine as the trail gains the lower forested slopes.

Miles 1.5 to 3: Pine Forest to Summit Ridge

Above the transition zone, the trail steepens further through open ponderosa pine. The summit ridge becomes visible above the trees. The final half-mile is the steepest section, gaining approximately 500 feet on a direct ascent to the ridgeline. The summit area is open with scattered pines; the high point is at approximately 8,400 feet.

When to Visit

The lower trailhead elevation makes this trail accessible from late May through October, significantly earlier than most higher-elevation Shoshone routes. Summer mornings are the best time to avoid heat in the lower sagebrush section. Fall (September-October) is excellent with cooler temperatures and clear visibility.

Check current conditions using the conditions-checking guide.

What to Bring

Many hikers carry the following for this trail:

  • 2-3 liters of water (no water sources on the trail; carry everything from the start)
  • Sunscreen and sun hat; the lower trail is fully exposed
  • Sturdy boots with ankle support for the steep rocky sections
  • Bear spray (bears are less common here than in the forest interior but are present)
  • Trekking poles for the steep descent

Individual water needs vary; the combination of heat and steep exertion makes hydration particularly important on this route.

Practical Details

No permit is required for day hiking as of 2026. No fee at the trailhead. Dispersed camping is permitted in the national forest; this trail's proximity to Cody makes it primarily a day-hiking destination. Follow Leave No Trace principles.

Frequently Asked Questions

Are there rattlesnakes on Rattlesnake Mountain?
The name likely reflects the area's historical character rather than an unusually high snake density. Prairie rattlesnakes are present in the lower sagebrush sections of the trail, as they are throughout this part of Wyoming. Watch your step in rocky terrain and avoid reaching under rocks or into brush without looking first.
Why is the trail rated strenuous for only 6 miles?
The 2,400-foot gain over 3 miles (6 miles round-trip) is steep by any measure. The average grade is approximately 800 feet per mile on the ascent, which is considered steep terrain. The strenuous rating reflects sustained grade, not technical difficulty.
What is the best time of year for this trail?
The lower elevation of the trailhead (around 5,000-6,000 feet) makes this trail accessible earlier than most Shoshone routes. Late spring and fall are good options to avoid the summer heat in the lower sagebrush sections.
Are there views from the summit?
Yes. The summit area provides clear views west toward Yellowstone and the Absaroka Range, east over the Bighorn Basin, and north toward the Montana border. On clear days, the Beartooth Plateau is visible to the north.
Is this trail near Cody, Wyoming?
Yes. Rattlesnake Mountain is visible from Cody and the trailhead is one of the closer hiking options to the city. It is a common training hike for locals building fitness for longer routes.
