Overview
Kings Hill Summit Loop circles the high terrain of the Little Belt Mountains in Lewis and Clark National Forest, offering a moderate day hike with good wildflower displays and wildlife watching accessible directly from US-89. The 6.4-mile loop gains 1,200 feet from the highway summit trailhead.
The Little Belt Mountains provide a significant wildlife corridor between the Rocky Mountain Front to the west and the isolated ranges of central Montana to the east. Elk, mule deer, and pronghorn use the open meadow terrain around Kings Hill.
The Highwood Mountains Loop provides a more demanding option in a different part of the Lewis and Clark forest.
The Route
The loop begins at the US-89 trailhead and climbs to the ridgeline above the summit, then circles through the open terrain before descending through forest back to the starting point. The ridge section offers the best views.
When to Visit
June through October. The high starting elevation makes this accessible from early June in most years. Wildflowers peak in July. Fall brings excellent foliage and elk activity.
Practical Details
Vault toilet at the trailhead. No fee. Water is not available on the route; carry all you need. Dispersed camping is permitted. Review Leave No Trace principles.
Getting There
From White Sulphur Springs, drive north on US-89 approximately 12 miles to Kings Hill Summit. The trailhead is at the summit parking area. A passenger vehicle can manage the drive.
Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
Safety Considerations
The moderate rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Lewis and Clark National Forest and may be unreliable in canyon bottoms or remote terrain.

Conditions can change rapidly in mountain terrain, and advance verification is always worthwhile.
