No matter your age, backpacking the Sierra to can be a life changing experience. Our Trans-Sierra Xtreme Challenge is an annual series of guided 75 mile backpacking treks across Sequoia and Kings Canyon National Parks. The inspirational journey traverses some of the most remote, least-traveled regions of the Sierra before culminating with an ascent on Mt. Whitney (elevation 14,505 feet), the highest point in the lower 48 states. This week-long trans-Sierra hike to Mt. Whitney is open to fit and motivated individuals of all ages and experience levels. You’ll cover 75+ miles in one week, with over 20,000 feet in cumulative elevation gain and 18,000 feet in cumulative elevation loss.

Afternoon departure, pack-check, overnight at trailhead
We’ll meet up with local and out of state guest in the Fresno/Clovis area between 1PM and 2PM on the day of departure, park cars, and then begin our journey together to Kings Canyon and Sequoia National Parks (about a 1.5 hour drive from the Fresno/Clovis area). Our goal is to make it to the trailhead just before dusk where we will do a final pack-check, get to know our team, and talk safety. If coming from the San Francisco Bay Area or Southern California, participants generally convene at 10AM on the day of departure at designated meeting points to carpool to Central California.
Day 1 – Horse Corral to Sugarloaf (moderate)
Trail: Begins at 7,800′, climbs to 9,300′ then descends to stream crossings and camp
After breaking camp at the trailhead, our Trans-Sierra trail begins near Big Meadow at 7,800′ and heads uphill to around 9,300′, then down to camp at 7,200′ near Sugarloaf. While the grade is moderate, expect this day to be among the toughest.
Day 2 – Sugarloaf to Big Wet Meadow (moderate)
Trail: Multiple stream crossings, trail climbs back to 8,500’
Today the trail undulates upward, with multiple crossings of prestine high sierra creeks, and one Roaring River, as we climb to near 8,500′ for our camp below granite cliffs and spires. At camp #2 we almost always have curious deer wander through. Keep your ears open for the occasional bear. Grrrrr…
Day 3 – Big Wet Meadow to Colby Lake (intense uphill)
Trail: Stiff climb to high-Sierra lake at 10,600’, get to camp just after lunch, rest
A stiff climb will bring us to one of the prettiest campsites in the Sierra, Colby Lake at 10,600′. A mid-afternoon swim, the chance to catch fresh trout, and the most amazing display of stars anywhere makes this camp special.
Day 4 – Colby Lake to Junction Meadow (intense up and downhill)
Trail: Climb to pass at 12,000’, then long intense downhill to 8,000’, most difficult day
An early start and 1,400′ ascent will get us to Colby Pass where we can view the Kern Canyon and the Mt. Whitney group. After a celebratory break, our trans-Sierra trek continues with a long and sometimes steep descent will get us to the Kern River for a crossing just before camp. This is the most challenging, and most breathtaking day.
Day 5 – Junction Meadow to Crabtree (moderate uphill)
Trail: Gradual climb to intersection with storied John Muir Trail and over 10,000′
A long, gradual climb on very good trail will get us to the John Muir Trail followed by undulating trail to camp near Crabtree Meadows at 10,800′. Our goal is to camp at the postcard-perfect campsite with an awesome view of the west side of Mt. Whitney.
Day 6 – Crabtree to Mt. Whitney and back (intense up and downhill)
Trail: Long day hike to summit and back with roughly 4000′ of elevation gain, and loss
Our early, before sun-up start will get us to the top of Mt. Whitney at 14,507 feet by lunch (weather permitting). The adrenaline will be flowing as we move past Guitar Lake, up the switchbacks, and parallel the Hitchcock peaks to the highest point of our trans-Sierra trail, and the highest point in the contiguous 48 states. After signing the book and taking pictures (you can also call home from the top) we’ll hike back to camp for dinner.
Day 7 – Crabtree to High Desert Camp (moderate to moderate-intense)
Trail: Morning climb to near 11,000′, mid-afternoon descent, and then climb back to 11,000′
We will leave our base camp and start our final segment to cars and civilization. We will hike a moderate trail for about 9 miles to our remote camp on the high desert above Rock Creek.
Day 8 – High Desert Camp to Horseshoe Meadows (moderate)
Trail: Relatively flat, then 500′ climb, before dropping to trail exit
An early start will get us to Chicken Spring Lake before lunch. We will cross over Cottonwood Pass and complete our Trans-Sierra hike with a descent down the eastside of the Sierra. After a cool drink and lunch we’ll load the vehicles and head back to the Clovis Area, and home to brag. Family and friends are welcome to meet us on the backside of the Sierra as we exit the trail near Lone Pine.
Departure and pickup locations: On the day of departure for your Trans-Sierra Xtreme Challenge trek, TSX will coordinate transportation from Central California (Fresno/Clovis area). We will also help facilitate carpool arrangements from the San Francisco Bay Area and Southern California to Central California on a trek by trek basis.
- Central California Pick-up Point: Clovis Cole Best Western, Clovis, CA – 2:00pm
- San Francisco Bay Area Meet Up Location: REI Dublin, Dublin CA – 10:00am
- Southern California Meet Up Location: REI Northridge – 10:00am
Please arrive at least 15 minutes prior to your confirmed pick up time. The Fresno/Clovis area is a 3 hour car drive from the Bay Area, and roughly 4 hours from Southern California. We will help coordinate and arrange car pools for participants coming from around the state when possible. Exact time and regional meet-up locations will be confirmed on a trek by trek basis.
Meals are not provided when in transit, however, we will stop for food and to refuel before reaching the trailhead. Our goal is to make it to the trailhead just before dusk. A light snack will be provided that evening at the trailhead.
Out-of-state guests / Pre- and post-trip accommodations: For guest traveling in from out of state, we suggest flying into Fresno, CA the evening before departure and staying at the Best Western Clovis Cole, in historic downtown Clovis or Hampton Inn and Suites Clovis. Both are about a 10 minute cab/Uber ride from the airport. We can pick you up at the hotel on the day of departure. If you plan on staying somewhere else, please let us know where you end up, and we’ll do our best to accommodate.
At the trailhead: Bring your personal items and a positive attitude! All group gear and food will be provided on the trail. Any major personal gear you’ve indicated you’d like us to provide (sleeping bag, tents etc.) will be waiting for you at the trailhead. Please also bring a small bag with a clean set of clothes. Before we hit the trail, we’ll give that bag to our return transportation. The clean bag will travel with return transportation and meet us as we exit the trail at the end of our Trans-Sierra trek.
Returning home: It’s difficult to predict exactly when your group will exit the trail near Lone Pine, Ca. Our itinerary has some buffer built in to account for unknowns such as group speed, trail conditions, weather etc. We will generally have a good sense of timing by the time we reach the summit of Mt. Whitney (day 6 or 7). One of your guides will check-in with return transportation from the summit. If you’d like to have friends or family meet you as you exit the trail, let us know and we can pass on the ETA and directions.
Our return transportation will meet us as we exit the trail on the eastern side of the Sierra. We will descend to Lone Pine to shower and share our last group meal. Finally, we’ll head back to your pickup location. This is a five-hour+ car ride. Bring some pocket money for meals on the drive back.
