Beula Lake Trail Description

Beula Lake Trail Description (Trailhead 8K6) - Light Traffic

Beula Lake is a peaceful destination located in the southwest corner of Yellowstone. It's an easy day hike or overnight trip at the southern edge of the Pitchstone Plateau.

Beula Lake lies at the southern edge of the Pitchstone Plateau about 2.0 miles north of the park's south boundary. The scenic drive along Ashton-Flagg Ranch Road, also known as the Grassy Lake Road, meanders through the Targhee National Forest which separates Yellowstone from Grand Teton National Park. It's approximately 9.0 miles from Flagg Ranch and the South Entrance of Yellowstone to the very inconspicuous trailhead along the northeast end of Grassy Lake Reservoir. There are no signs at the trailhead but if you look for the obvious path heading north from this small pullout you'll be in the right spot. The trail begins just outside the park's southern border within the Targhee National Forest.

From the parking lot the Beula Lake Trail climbs at a moderate grade over loose gravel, gaining most of its 350 feet of elevation over this first mile. There is a nice view of the reservoir at 0.25 miles which was constructed in the late 1930s to provide water for the farmland in Idaho's Snake River Plain further to the west.

At 0.5 miles the Beula Lake Trail intersects with the South Boundary Trail which follows the southern border of Yellowstone in an uncharacteristically straight line east for 6.6 miles to the South Entrance Station, and west for 1.7 miles to the Grassy Lake Trailhead (9K6). The trail enters Yellowstone National Park at this junction. From here the trail continues climbing through lodgepole pine forests for another half mile before leveling off. In mid July the trail can be very dusty and the biting flies are abundant compared to the mosquitoes but regardless it's always a good idea to carry insect repellent in Yellowstone during the months of June and July.

At 1.2 miles the trail begins a very gradual descent to Beula Lake and in many places the trails seems almost flat. Lodgepole pines are the predominate species throughout this region and on the west side of the trail young trees grow in nearly impenetrable clusters. To the east the taller and more mature trees, untouched by the fire, stand tall against the bright blue sky. Forest fires are an integral part of the Yellowstone ecosystem and this type of scenery is common throughout the park.

Approximately a quarter of a mile from the lake its sparkling waters are visible between the thin trunks of lodgepole pines. From this vantage point the trail drops steeply to meet the lakes southwestern shoreline. There are two nice campsites located at Beula Lake, 8A1 and 8A2 (★★★) and both are very similar but 8A2 is much more private because it is situated at the end of the trail.

The water along the shoreline is extremely shallow and a number of partially submerged trees reach outward toward matts of yellow pond lily that mark the edge of deeper water. In July large numbers of boreal bluet (damselflies) can be seen darting between blades of grass at the water's edge, their bright blue bodies clinging to strands of grass with delicate legs. Overhead a pair of osprey hovered patiently, waiting for the chance to swoop down on any unsuspecting fish.

Beula Lake is the headwaters of the Falls River which heads west along Yellowstone's southern border where it is eventually joined by the Bechler River. The lake contains a nice population of cutthroat trout that average about 12 inches. A float tube makes navigating the lake much easier.

NOTE: Many of the trailheads along the Ashton-Flagg Road begin in the Targhee National Forest just outside of Yellowstone's southern borders. Trailheads are often unmarked and may be difficult to locate so a good map is imperative. The Ashton-Flagg Road (Grassy Lake Road) runs east and west for about 50 miles between the South Entrance of Yellowstone and Ashton, Idaho. Approximately 32.0 miles of the road is unpaved and can be difficult to travel during the spring. The road is closed during the winter. There are no services along this route.
