Beula Lake Trail

Overview

A quiet, moderate out-and-back to a pretty, lily-pad-fringed lake, Beula Lake Trail runs about 5.3 miles round-trip with roughly 650–700 feet of total elevation gain. Expect a stout opening climb, a mostly mellow forest cruise, then a short, steeper drop to the shore. It’s more about the destination than big views en route—pleasant, peaceful, and a solid pick if you want birds, fishing, and a backcountry feel without a huge day.

What You’ll See

The route threads through lodgepole pine forest, including patches that burned in 1988 and have since come back in a mosaic of ages. Early on, you can peek back toward Grassy Lake Reservoir; later, brief windows open north to the Pitchstone Plateau—one of Yellowstone’s youngest rhyolitic lava flows, about 70,000 years old. Near the end, Beula Lake appears through the trees before a steeper descent to its clear water and lily pads. Expect downed trees along the shoreline and waterfowl on the lake; some hikers also note glimpses toward nearby Hering Lake.

Trail Notes

From the pullout, the trail climbs quickly (reaching a junction with the South Boundary Trail around 0.6 mile—continue straight). After the initial push, it rolls gently along a wooded ridge before dropping the final stretch to the water. A shoreline path continues past two backcountry campsites and ends at the far site; informal fisher paths may continue beyond. The walking is almost entirely on natural tread with occasional short, steeper grades. Dogs are not permitted.

Access and Parking

The trailhead sits along the gravel Grassy Lake Road (Flagg Ranch–Ashton route), roughly 9 miles west of Flagg Ranch. Look for a small, unsigned pullout on the north side of the road near the east end of Grassy Lake Reservoir; a kiosk sits a short walk up the trail. The road can be rough with potholes and washouts—avoid low-clearance vehicles and check early-season conditions. No reliable water until the lake and users report no restroom at the trailhead.

Best Time to Hike

Late spring through early fall is the sweet spot. Early summer can bring road washouts, and mosquitoes can be intense in June–July, especially near the lake and in still air—start early or aim for a breezy afternoon. Weekdays and early mornings help with solitude. Shoulder-season visits (when the road is open) mean fewer bugs and fewer people.

Who Will Love It (and Who Won’t)

If a peaceful lake lunch spot, birding, or casting for native Yellowstone cutthroat trout sounds appealing, this one delivers. Trail-hardy kids often do well thanks to the mellow middle miles and modest overall length. If you’re chasing dramatic scenery the whole way, it’s more “pleasant forest walk to a nice destination.” Consider pairing it with a nearby waterfall outing to round out the day.

Tips

• Carry all the water you need; shade helps but it can feel warm on calm days.
• Fishing requires a Yellowstone fishing permit; know the regulations.
• The unsigned start is easy to miss—track your mileage from Flagg Ranch and watch for the pullout.
• The return climb from the lake is short but punchy—save a little gas for it.
