Cottonwood Lake From Smoot: A Local's Read On The Season Above Town

The drive up Cottonwood Creek Road takes about twenty minutes from the highway turnoff south of Smoot. The trail season it opens onto lasts about twenty weeks. That mismatch is the whole point of this post. If you live down here, you already know the road is there. What is harder to hold in your head is the order the drainage wakes up, the week Slide Lake is worth the walk, and the moment Wagner takes over as the honest destination. This is a rotation, not a single hike.

The road opens later than the calendar suggests

Cottonwood Lake Campground sits at 7,000 feet in the Salt River Mountains, approximately 13 miles southeast of Afton, and the group campsite operates on a May 1 through October 1 service window. Those dates are administrative. The mountain does not read them. As late as April 23, a Winter Weather Advisory was in effect and the forecast still called for snow showers with highs near 34 and gusts to 26 mph in the country just above town. Water was on but the drainage was still shedding winter.

Read that against the road itself. From Afton, Highway 89 south about 8.3 miles, left on Cottonwood Creek Road/County Road 153, into the forest where it becomes FS-10208, then about 6 miles to the campground. From Smoot the drive is shorter, but the road is the same road. Campers describe it plainly: a mostly one-lane road with rough sections, potholes, and washouts, so drivers should proceed slowly, especially when towing. Late June is usually when a low-clearance vehicle can make it comfortably. Early June is a coin flip.

The practical implication for people who live here: the first two weekends the gate is technically open are not the same as the first two weekends worth going. If you are running errands in Afton in mid-May, the drive up FS-10208 will tell you more than any forecast.

The lakes are not interchangeable

Most people talk about "Cottonwood Lake" as if the drainage has one destination. It has three that matter, and they hand off through the summer.

Cottonwood itself offers boating for smaller craft, no ramp, and fishing for brook and cutthroat trout. It is the family day, the after-work cast, the place you take the in-laws. It is not the hike.

Slide Lake is. The trailhead is tucked behind Cottonwood Lake and follows a mellow 3.5-mile out-and-back with about 500 feet of elevation gain, making it a good option for families and casual hikers. The catch is seasonal: the lake fills with snowmelt in early summer but tends to dry out later in the season. If you show up in late August expecting water and a picnic, you may find a basin. The window is real, and it is short.

Wagner is the fallback that no visitor knows about. You can continue on the trail for a few more miles to reach Wagner Lake, another alpine lake that stays fuller later in the season. Once Slide is down to mud, Wagner is the honest answer to "where should we go today." That is the local read, and it is worth holding.

When you want a real day

Two peaks off the same road ask more of you. The longest trail in the area is Wyoming Peak Trail, estimated at 15.0 miles, with 3,277 feet of elevation gain. Mount Wagner Trail has the most elevation gain of any trail in the area, at 3,349 feet. These are not extensions of a lake hike. They are the day.

Mount Fitzpatrick, the range's high point, sits on a different approach. The trail starts at the Crow Creek Trailhead, merges into the Way trail after roughly 4 miles, cuts west a little over a half mile later and climbs through the cliffs, then heads south about a mile to Lower Crow Creek Lake at 6 miles total, with Fitzpatrick about 2.5 miles beyond. That is a long day out and back, but it is the summit view of the Salt River Range from your own front yard.

If someone visiting from out of state wants to see what you actually live next to, this is the answer. Not the campground. The ridge.

The overflow map

Cottonwood gets busy on holiday weekends. Two nearby options absorb the spillover.

Bridger-Teton hosts several campgrounds including Allred Flat and Cottonwood Group Campsite, both operating seasonally from late May through mid-September, and Salt River Pass offers free dispersed camping with basic amenities like picnic tables and vault toilets. Allred Flat sits farther south along Highway 89 and reads differently: great flyfishing on the Salt River, fairly private and quiet, good Verizon cell service. That last detail matters if you are on call.

The Greys River side is a different world entirely, and one that most Smoot residents rarely see. The Cazier Cabin is a historic Forest Service guard station built by the Civilian Conservation Corps in 1933, reservable through Recreation.gov, and the trip in is the point: the closest town for groceries is Alpine, a 46-mile drive north on a low-speed gravel road. It is closer to Smoot as the crow flies than as the truck drives, which is the local joke worth knowing.

A note the trailhead signs make quietly and worth taking loudly: "Be 307 Aware": the 307 Channel on FRS and GRMS capable radios can help search and rescue teams get you home safely. Cell service disappears somewhere between the forest boundary and the campground. A cheap FRS radio in the glove box is the sort of thing you buy once and forget you own until the day it matters.

A season's rhythm, from Smoot

If you moved here recently and you are still figuring out the year, here is what the drainage asks of you month by month.

• Late April to mid-May. Watch the road, not the calendar. Snow showers still show up in forecasts at 6,600 to 7,600 feet.
• Late May. Group campsite services turn on May 1, but the road settles in around now. The services operate May 1 through October 1 and the campground opens onto 18 campsites total, first come first served except for site 13.
• June. Slide Lake is at its best. Snowmelt is in the basin, the creek crossings are real, and downed trees from winter are still being cleared. Reviews from this window mention creek crossings, downed trees, and rapidly flowing water.
• July. Wildflowers, warmth, the day-use lot fills by ten on weekends. This is when Wyoming Peak and Mount Wagner become reasonable objectives if you have the legs.
• August. Slide Lake drops. Shift to Wagner. Fishing on Cottonwood stays strong: the lake has brown and cutthroat trout, and evening fly fishing runs excellent.
• September. Aspens turn on the approach road. The campground is emptier than at any point since Memorial Day. Bring layers. Mornings at 7,000 feet are cold.
• October through April. The drainage becomes the 11.5-mile out-and-back Cottonwood Lake Snowshoe Route, moderately challenging, averaging about 4 hours 7 minutes. Avalanche awareness matters. The Bridger-Teton reminds users to identify avalanche terrain, avoid steep unstable areas, stick to lower-angle routes, and check for warning signs like cracking snow or fresh avalanche debris.

The small print residents forget

Two rules catch new arrivals off guard. First, possessing, storing, or transporting non-pelletized hay, straw, or mulch in the Intermountain Region is prohibited unless it is certified as weed free by the state where the product originated. If you keep horses and you head up for a ride, the bale in the trailer matters. Second, the east loop allows ATVs because a motorized trail takes off from the back of the loop, and three walk-in sites are also available for tent campers. The west loop does not. Group people up correctly on the reservation and you avoid the awkward mid-weekend shuffle.

Questions about permits, closures, or a specific stretch of FS-10208 go to the Greys River Ranger District office at 671 North Washington Street in Afton, 307-886-5300, Monday through Friday, 8:00 am to 4:30 pm. Call before Memorial Day if you are planning a group weekend. They know which culverts washed out.

The version of this post that lives on a hundred other sites lists Cottonwood Lake as a "hidden gem near Afton" and calls it a day. That is not what you moved here for. The drainage rewards paying attention: to the road in May, to Slide's water level in July, to Wagner when Slide gives out, to the ridge above when the day is long enough. It is the kind of local knowledge that accumulates one summer at a time.

When your own plans eventually turn from summer weekends to something bigger, whether that is buying acreage above the highway, selling the place you have outgrown, or helping family find their way south from Alpine, Patty Speakman and the team are here in Star Valley and glad to talk.
