Climb Gannett Peak Wyomings Tallest Mountain

Tom’s experience climbing Gannett Peak:

Gannett peak is the highest point in Wyoming and is often considered the most difficult state highpoint in the lower 48 states. Located in the Wind Rivers, Gannett is among some of the prettiest mountains I’ve ever seen.

Getting anywhere in the Wind Rivers is difficult as there are often many steep passes between you and your destination. We approached Gannett from the West along the Pole Creek Trail.

Gannett Hike

From the Pole Creek Trailhead you will need to hike 16-18 miles to the Titcomb Basin. The trail doesn’t gain a ton of elevation overall during this stretch but it does go up and down quite a bit making the trek a little difficult.

Hiking Gannett

Our goal was to get to Titcomb on day one, summit day two and head back to the trail head on day three. Along the way to Titcomb you will pass multiple beautiful lakes but the best part is definitely Titcomb Basin.

Gannett Climb

My dad always says that the Wind Rivers has some of the best scenery in the world it just takes 15 to 20 miles until you get to it from any trailhead. I have found that to be pretty much the case on my trips here. We set up camp at Titcomb Basin.

Climbing Gannett

If you want to camp close to Lower Titcomb Lake thats fine but will make summit day longer and more challenging. If you are concerned about time and energy on summit day you may want to camp closer to the base of Bonnie Pass.

Gannett Peak Summit

We decided to camp near Lower Titcomb so that we wouldn’t have to carry our backpacks as far in day one and three but it did make summit day more difficult. Either way there are plenty of excellent campsites all around both lakes.

Gannett Peak Bergschrund

On summit day be sure you wake up early. We left our campsite at 3:15 but we were at the far end of Titcomb. I would suggest being on the pass as early as possible so that you are hiking up ice instead of slush. You will climb up Bonnie Pass which was covered in snow and very steep. It almost appeared as a mountain itself.

Bergschrund Gannett Peak

We reached the top of Bonnie right at dawn and was able to watch the sun rise from there and got our first view of Gannett. From here we regrouped and planned out our route to the summit. The trail is mostly snow with a few rocky scrambles up Gannett. You will head around the backside of the rocks you can see from Bonnie and head towards the Bergschrund. The Bergschrund is usually the most dangerous part of the mountain. When we were climbing, there was plenty of snow and we didn’t feel like we were in too much danger. However the glaciers are very steep and ice axes and crampons are necessary.

Summit of Gannett Peak

Most groups were also roped up however we weren’t after we talked to a few groups who also thought it wasn’t necessary. The views from the summit are gorgeous and we really enjoyed our time on top. We also got cell service so it was fun sending summit photos to loved ones. We headed back down the mountain over Bonnie and back towards our tent. From the Titcomb base of Bonnie Pass to the summit of Gannett and back to the base of the Pass took us about 11 hours round trip with a few pretty decent brakes. However we passed multiple groups that took over 17 hours for the same stretch. We camped that night and headed out after a great nights rest the next day.

Gannett Peak Wyoming

Total round trip mileage was about 40 miles with total elevation gain of about 9050′. Dogs are allowed in the Wind Rivers. We were very lucky that the weather was so good for us the whole time and the snow was in such great condition.

Tom’s Rating:

Trail Info: The trailhead starts right next to a campground and there is a ton of parking available. From Pinedale, Wyoming, head towards head towards Fremont Lake. Eventually the road will change to Skyline Drive. The road was in poor condition when we went but any vehicle should be able to make it to the trailhead. The road will turn to dirt and the trailhead is on the left right near the change to dirt. There are outhouses at the trailhead and plenty of sings to get you to the Pole Creek Trailhead.

Explore the beautiful Wind Rivers Traverse

Tom’s Experience on the Wind Rivers Traverse:

We set out to do the Wind River High Route following this very detailed guide but due to time constraints and weather we had to change our route a little bit.

Big Sandy Trailhead Wind Rivers Traverse

We started day one at the Big Sandy Trailhead and headed into the wilderness area. We walked pass Big Sandy Lake and into the Circ of the Towers and Lonesome Lake by way of Jackass Pass.

Big Sandy Lake

The pass was a little rocky and would be very difficult to cross with a horse but hiking it wasn’t too bad.

Jackass Pass

The Circ was a very pretty area with steep granite rock faces surrounding the trail.

Circ of the Towers

We stopped here for lunch and as we were eating we watched two different fishermen catch multiple fish. There were also a few rock climbers which were fun to watch.

Lonesome Lake

From here, we headed up Texas Pass which was very steep and there wasn’t much of a trail to follow. We dropped down Texas Pass into a valley that is behind the Circ of the Towers.

Hiking Circ of the Towers

The trail was pretty flat and easy to follow all the way up until Pyramid Lake at which point the trail disappeared and we had to bushwhack.

Wind River Traverse

We decided to hike just a little bit past Pyramid Lake to an unnamed lake and spend the night there. We had great weather on the first day.

Hiking in the Wind Rivers

On day two, we woke up to a beautiful sunrise and the temperature had dropped.Mount Bonneville

From here, we tried to stay as high as possible as we walked through a valley beneath Ambush Peak and Raid Peak.

Bonneville Pass

There were pretty lakes below us and more steep granite cliff faces. I don’t think I have ever seen so many steep granite cliffs in one area any where else. There was a very rocky pass just below Mount Bonneville that led to Bonneville Lake.

Hiking Bonneville Pass

We were rock hopping most of the way and there was no trail which really slowed us down. We descended to Bonneville Lake and went up another pass which was really fun. There was no trail but the rock ledges kind of lead you up the pass.

Wind River Traverse south to north

We came to one part where the ledge slowly got narrower until you had to use your hands and climb to the other side. The pass then descends down to Lee Lake and Middle Fork Lake. This was also a very pretty section and one of my favorites from the whole trip.

Heading to Middle Fork Lake

The rock hopping was really difficult to try to keep any sort of pace and it really slowed us down. We stopped for lunch at Middle Fork Lake. By this time, clouds were starting to roll in and it looked like a storm was coming. We decided to stop following the Wind River High Route Guide at this point since we were running behind schedule and the weather didn’t look like it would be safe to stay up high. So we descended down and started following the Old Highline Trail towards North Fork Lake. After about an hour of leaving Middle Fork Lake the mountains were completely covered in clouds and I’m sure we would have been in a white out and had a difficult time progressing, especially without a trail to follow. We made it to North Fork Lake with just mild rain that day and set up camp there.

Wind River River Crossing

We did however have two river-crossings where we had to roll up our pants and take off our shoes in order to try to keep everything dry. On the third day We left North Fork Lake and headed towards Hat Pass.

Storm in the Wind River

Hat Pass wasn’t too bad as far as passes are concerned and we got up and over that pretty quick. About this time a huge snow storm arrived and we were forced to put on our rain coats.

Wind River Snow

It rained and snowed most of this day but since we were on trails we were still able to progress along. We crossed two passes and walked through Bald Mountain Basin during the storm. Bald Mountain Basin was another one of my favorite spots along the trail and a place I hope to make it back to some day. We ended up coming to another river crossing and since we were already soaked from the rain we decided to just walk through this time. We came to Lester Pass which was a really difficult pass to climb up. It was very long and very steep. This dropped us down into Little Senaca Lake which was a very pretty area as well. We saw numerous people around these lakes that were camped there trying to avoid the rain.

Lower Jean Lake

We continued on and reached the Fremont Crossing which has a bridge over it which was nice. We decided to set up camp at Lower Jean Lake and it was a very pretty area as well.

Lower Jean Lake Clouds

It was cold that night but it didn’t rain after we stopped hiking which was nice. On the morning of the fourth day we had to make it to Green River Lakes Trailhead so we really tried to push it.

Wind Rivers Traverse Sunrise Wind River Range

We hiked over Shannon Pass and Cube Rock Pass both of which were very rocky.

Entering the Storm Wind Rivers

Our final pass of the trip was Vista Pass which wasn’t very steep and was pretty easy to descend.

Hiking through the Wind Rivers

From there the trail was mostly flat with a few downhill sections as it follows the Green River out of the wilderness area.

Bald Mountain Wind Rivers Traverse

Squaretop Mountain was a very pretty granite peak that was fun to hike under. We also saw a ton of people the closer we got to the trailhead.

Green River Wind Rivers Traverse

Overall we hiked over 80 miles but it was through some of the prettiest mountains in the US. Dogs are allowed in the Wind River mountains.

Green River Trailhead Wind Rivers Traverse

Tom’s Rating:

Trail Info: Getting to the Big Sandy Trailhead (the southern trailhead) can be a little difficult since you must travel about 46 miles on unmarked dirt roads. Most cars should be able to make it to the trailhead if the dirt is dry but a high clearance vehicle is nice. The easiest way to get to the trailhead from Farson Wyoming is to head 4 miles east of Farson to an intersection that is signed for Big Sandy Trailhead, turn left here and restart your odometer. All mileage will be from this turn. At 21.5 miles bear right. At 23 miles turn left. At 29.5 miles bear left. At 34.5 bear right and the parking lot will be at about mile 45.

To get to the Green River Lakes Trailhead (the northern trailhead) from Pinedale, drive 7 miles west on US Highway 191, turn right (north) on Wyoming Highway 352 and drive north to the National Forest boundary where the pavement ends (about 30 miles). Continue north on Forest Road 600, staying on the right side of the river. After 17 miles the road ends at the campground and trailhead.
