The Howard Eaton Trail through Yellowstone's Canyon area offers a moderate backcountry experience connecting a chain of pristine alpine lakes: Cascade Lake (2.6 miles), Grebe Lake (4.5 miles), Wolf Lake (6.3 miles), and Ice Lake (10.7 miles). This section traverses lodgepole pine forest, wet meadows, and marshland in grizzly habitat, providing solitude just minutes from the park's busy Canyon Village area. The trail works well as a 2-3 day out-and-back or through-hike, with designated campsites at each lake. Anglers will find this especially rewarding—Grebe Lake was recently restored with Arctic grayling and westslope cutthroat trout as part of a native fish refuge project.
The route follows mostly flat terrain with minimal elevation gain (around 1,100 feet total), making it accessible to backpackers comfortable with remote travel. Expect muddy conditions and aggressive mosquitoes through July, followed by prime hiking from mid-August through September. This isn't a dramatic alpine traverse—it's a quiet meander through Yellowstone's interior forests and wetlands.
A backcountry permit is required year-round for overnight camping and must be obtained through Yellowstone's reservation system. The process has three windows:
Early Access Lottery: March 1-20, applications cost $10 (non-refundable). If selected, you receive a 15-20 minute window on a predetermined date to book your campsites.
Regular Reservations: Open April 26 through October 31 on Recreation.gov for sites not claimed in the lottery. Permits cost $5 per person per night plus a $10 reservation fee ($25 total for a solo two-night trip). The $50 Yellowstone Annual Backcountry Pass waives the nightly fee if you plan multiple trips.
Walk-In Permits: Available at backcountry offices for unreserved sites, though popular lakes like Grebe often book months ahead.
Camping is permitted only at designated sites (4G2, 4G3, 4G4, 4G5 at Grebe Lake, plus sites at Cascade, Wolf, and Ice Lakes). Three-night maximum per campsite. Campfires allowed only in established fire rings—bring a stove as backup. Group size limits vary by site but generally cap at 8-12 people. Dogs, bikes, and motorized vehicles prohibited.
Fishing requires a separate Yellowstone fishing permit. All native fish—including Arctic grayling—must be released unharmed. Float tubes require a boating permit.

Mid-August through mid-September offers the optimal window. Snow typically melts by early July, but trails remain wet and muddy through the month with peak mosquito populations. The NPS specifically warns of "many biting insects" through July on this route. By mid-August, trails dry out, bugs decline significantly, and weather stabilizes.
Early October can be excellent for solitude and fall colors, but prepare for cold nights and possible snow. The first significant snowfall usually arrives in mid-to-late September. Shoulder season (late June, early October) means fewer permit conflicts but greater weather uncertainty.
Daytime summer temperatures range from 70-80°F, dropping to 40s at night. Afternoon thunderstorms are common July-August—lightning risk is moderate given the forested terrain, but exposed ridges near Observation Peak warrant caution. Pack rain gear and monitor forecasts daily.
Water is abundant but requires treatment. The trail passes three named water sources plus Cascade, Grebe, Wolf, and Ice Lakes. Treat all water—giardia is present park-wide. Lakes provide reliable access, but the muddy shorelines and waterfowl populations make a filter with pre-filter or chemical treatment preferable to UV.
Underground springs feed Ice Lake year-round. Grebe Lake's outlet at 2.8 miles from the Grebe Lake junction provides flowing water. Cascade Lake has accessible shoreline. Seasonal streams cross the route, but don't rely on them after mid-August.
No resupply options exist along the trail. Canyon Village (0.25 miles from the trailhead) has a general store with limited backpacking food—expect granola bars and instant meals, not dehydrated dinners or specialty items. West Yellowstone (14 miles from the park's west entrance) offers better selection but requires leaving the park. Plan to carry all food for your trip.
Mail drops are not practical for this short route. Most backpackers resupply in gateway towns (Gardiner, West Yellowstone, Cody) before entering the park.
Grizzly bears are the primary concern. The Canyon area sees regular grizzly activity, and the trail passes through prime habitat. Carry bear spray in a hip holster, not your pack. Travel in groups of three or more—91% of Yellowstone bear injuries since 1970 occurred to solo hikers or pairs. Make noise in dense forest sections and around blind corners. Food storage poles are provided at all campsites; hang food 10 feet high and 4 feet from poles. Check with the backcountry office for recent bear activity before departing.
Navigation can be challenging. The trail fades in meadow sections where animal trails create confusion. Bring a map, compass, and downloaded GPS track. The route is generally well-cairned near lakes but less obvious in forest.
Mud and stream crossings define July travel. One trip report mentioned "wet feet will be the norm" in early season, with at least one ford requiring wet crossings by late August. Waterproof boots help, but many backpackers switch to trail runners and embrace wet feet.
Mosquitoes and biting flies are relentless through July. Bring a head net, DEET or picaridin, and treat clothing with permethrin. August sees dramatic improvement.
Weather swings are unpredictable at 8,000+ feet elevation. Snow has fallen on July 4th. Always pack insulation and rain protection regardless of forecast.
The Howard Eaton Trailhead sits 0.25 miles west of Canyon Junction on the Norris-Canyon Road (Grand Loop Road). From Canyon Village, drive west toward Norris; the trailhead is a small pullout on the right with limited parking for 4-5 vehicles. Arrive early during peak season or risk roadside parking.
Nearest Airports: - Bozeman Yellowstone International (BZN): 100 miles, 2 hours to West Entrance or 90 miles to North Entrance (Gardiner). Best year-round option with most flights. - Jackson Hole (JAC): 72 miles, 1.5 hours to South Entrance through Grand Teton. Scenic but pricier. - Cody/Yellowstone Regional (COD): 53 miles, 1 hour to East Entrance. Limited flights. - West Yellowstone (WYS): 3 miles from West Entrance, but seasonal service only (limited summer flights).
From any airport, you'll need a rental car—no public transit serves the park interior.
Trailhead Access: The Norris-Canyon Road typically opens in mid-to-late April and closes in early November. Spring opening depends on snowpack. Confirm road status on the NPS website before traveling. Canyon Village has gas, groceries, lodging, and a visitor center.
Shuttles: Yellowstone tested a pilot shuttle at Canyon Village in 2021, but no permanent service exists. This is a car-dependent park. For through-hikes, you'll need to arrange a vehicle shuttle between trailheads or hitchhike (common and generally safe in summer).
Parking: The trailhead pullout fills quickly. Overflow parking is available at Canyon Village, adding 0.5 miles of road walking.
Campsite 4G2 at Grebe Lake sits right on the south shore, closest to the trailhead at 3 miles total. 4G3 is on the northwest corner—slightly farther but more private. Both book fast in the lottery. Wolf Lake and Ice Lake sites see less pressure and make good alternatives if Grebe is full.
Bring trekking poles for muddy sections and balance on log crossings. Camp shoes are worth the weight—your boots will be caked in mud by evening.
Float tubes are popular at Grebe Lake for fishing, but require a park boating permit ($5 for 7 days, $10 annual). Arctic grayling average 10-14 inches. Fish early morning or evening when rises are visible.
Timber wolves occasionally pass through—howling at night is possible, especially near Grebe. It's a thrill, not a danger.
Wildflowers peak in early July along meadow edges: lupine, Indian paintbrush, elephant head. But you'll pay for it in bug bites.
Cell service is nonexistent. Bring a GPS communicator (inReach/Garmin) for emergencies.
The ice blocks that gave Ice Lake its name were harvested in the early 1900s to supply Norris Geyser Basin concessions. Underground springs keep it cold year-round—swimming is bracing but possible in August.
Avoid this trail during the September elk rut if you're noise-sensitive. Bulls bugle aggressively near meadows, especially at dawn.
