Hike Description

Hike Description


Very few hikers are drawn to the Bull Moose Trail. The remote trailhead deters hikers from approaching via Decker Flat, and virtually nobody is intrigued enough to climb over the eastern moraine from the Redfish Inlet Hikes. What appears to be a long, flat slog through dense forest, however, is actually a series of open, high-elevation meadows. There are some nice views of Mount Heyburn and nice early to mid-summer wildflowers. The biggest challenge is finding and following the trail within the first mile.

From the small parking area on the north side of the bridge, there is no trail sign or even any appearance of a trail. Have confidence and start walking due west into the tall grass. Within 100 yards, hikers should be able to pick up a trail that contours along the southern edge of the Redfish Ridge. After 0.6 miles the trail disappears and turns south to cross an unnamed creek in the tall grass. After crossing two marshy channels, it may take a bit of wandering to find the more defined trail on the south side.

If you make it this far, you are in the clear! A good trail climbs gently through a Lodgepole pine forest on the north side of Bull Moose Creek, which is never really visible. It leads to a section of steeper, rutted trail at 1.4 miles. At the top of this pitch, the trail drops down to Bull Moose Creek. For the next mile or so, the trail passes through three large alpine meadows. Depending on the season and snow melt, large sections of the trail and upper meadow may be completely flooded. These conditions of flat, open ground and ample water can lead to beautiful wildflower blooms and good opportunities to see elk and deer foraging. There are also some great views of Mount Heyburn and the Grand Mogul Ridge.       

After re-entering the trees, the trail climbs gradually at first then steepens as it nears the moraine ridge. Unless you are intending to loop across the moraine and down Redfish Ridge (or descend to the Redfish Inlet Hikes), there is not much reason to continue beyond the upper meadow.
