Thousand Island Lakes


  • Dazzling high country of the Sierra Nevada

  • Serenity and profound beauty of the eastern Sierras
  • Summit attempt on Mount Ritter

Explore the High Country of the eastern Sierra along The John Muir Trail and the famous Pacific Crest Trail on this 5 day alpine adventure! Escape the crowds of Yosemite National Park and venture deep into the solitary reaches of the lesser known, but equally beautiful, Inyo National Forest. Camp along the banks of Thousand Island Lake and admire Mount Banner and Mount Ritter from camp as they dominate the skyline and reflect boldly in the vast island-speckled lake. Our second day brings us to Ediza Lake, where we will spend two nights in the shadow of the mighty Mount Ritter. Our third day we rise with the sun and begin our journey to the peak of Ritter with light packs and plenty of determination. Climbing to the top of Mount Ritter is a tremendous feat, but not mandatory (guests are welcome to relax in camp if they're not up for the climb).

Trip Itinerary

Day 1

Day 1 begins with a rendezvous at the iconic Mobil Gas station at the corner of Highway 395 and Highway 120, just before the small village of Lee Vining. We will meet at 6pm, conduct an orientation meeting and have dinner together at the famous “Whoa Nelli Deli” located within the Mobil. After a surprisingly delicious meal at what may very well be the most gourmet gas station cuisine on earth, we hop into the company vehicle and cruise up the hill to our ready-made campsite. Finally settled, we enjoy our first alpine sunset amidst the excited chatter of a group embarking on an amazing adventure in the High Sierra.
Day 2
  • Hiking Mileage: 6.3 miles
  • Elevation Gain: 2624 feet
  • Elevation Loss: 900 feet
We rise with the sun and breakdown camp for an early start on the road to the Silver Lake trailhead. As is usually the case, the first day is our most demanding day of the trip. The hike begins in earnest, switch-backing alongside the rails of an old push-car track on its way up the slope toward the dams at Agnew Lake. From here, well head south toward Clark Lakes and catch the famous Pacific Crest Trail for about a mile. Finally we reach our stunning campsite along the banks of Thousand Island Lake. We will pitch camp and enjoy a well earned hot meal before falling asleep under a starry Sierra sky.
Day 3
  • Hiking Mileage: 6 miles
  • Elevation Gain: 1300 feet
  • Elevation Loss: 1000 feet
Today we are off to Ediza Lake, at the base of the tremendous mountains we have spent the night admiring. The trail immediately brings us to the sister of Thousand Island Lake, the beautiful Garnet Lake. It shimmers in the morning sun as we make use of this pleasant hour to cover ground. After a challenging climb into the higher reaches of the mountains we arrive at our base camp at Ediza Lake. From here, we can see the route we will use to attempt the summit of Mt. Ritter. Over dinner, we discuss our plan and review mountain safety as we prepare to conquer the peak of Mt. Ritter. Not all of us came to climb mountains, and some may choose to remain at camp the next day. The decision is yours and there’s no way to go wrong.
Day 4
  • Hiking Mileage: 5 miles
  • Elevation Gain/Loss: 3800 feet
Today is your day to do as you choose, either enjoy a relaxing day reading by the lake or hit the trail with your guide to climb the domineering Mt. Ritter. Whatever activity you choose, you will surely be left in awe of the tremendous beauty and serenity of this alpine jewel. Discover why you came out here in the first place and end the day utterly satisfied with your accomplishments, whatever they may be.
Day 5
  • Hiking Mileage: 6 miles
  • Elevation Gain: 1000 feet
  • Elevation Loss: 1300 feet
We awake to hot beverages, well-rested, in perpetual disbelief of our surroundings and ready to see some more. Though we are simply retracing our trail back to Thousand Island Lake, the mountain scenes are new and it is hard to believe we ever walked this trail before. We arrive at our familiar campsite along the banks of the lake and savor our last alpine sunset as the reflections of Mt. Ritter and Mt. Banner ripple in the gentle evening breeze.
Day 6
  • Hiking Mileage: 9 miles
  • Elevation Gain: 328 feet
  • Elevation Loss: 2624 feet
Today is a longer hike but a different trail then Day 1. After breakfast, we pack up our camp and hit the John Muir trail for a short climb. After joining the Rush Creek Trail we will start our decent toward the trailhead. Along the way we will pass beautiful Waugh and Gem lakes and end up where we started at Agnew Lake. After a quick descent finally we make it to the truck. As we cruise through the desert, well recall the highlights of our adventure with new friends and prepare for whatever’s cooking at the Whoa Nelly Deli!

Please Note: We always do everything in our power to follow the set itinerary, however it can change occasionally based on temporary access restrictions, weather, lodging/campground availability, guest ability/injury, natural events like fires and flooding, and other potential causes.

Guide Shifts

Eastern Sierra guides work daily shifts from 5 a.m. to 9 p.m. During off hours (9 p.m. to 5 a.m.) the guides' time is their own, and they are free to sleep, rest, take personal time, postpone guest requests until the next morning, and any other legal, reasonable activity people engage in when not working. We ask all guests to respect the guides' off-duty hours by not waking or asking anything of them unless there is a true emergency. Also, state law requires that employees receive an uninterrupted 10 minute break every four working hours, so guides are required to take four 10 minute breaks between 5 a.m. and 9 p.m.

Group Size and Age Restrictions

The standard group size on backpacking trips is 6 guests and 1 guide, with a maximum of 10 guests and 2 guides. If you have more questions about group size, please give us a call at 1-800-715-HIKE (4453) and we'll answer all your questions.

Age restrictions are as follows:
  • 12 and older to join scheduled tours (mixed groups)
  • 10 and older to join private tours, with final approval on a case by case basis
  • specific logistical requirements (such as porter or stock assist) determined on a case by case basis

Weather in the Sierras

Being a high mountain environment, the Sierra Nevada Mountains are prone to sudden temperature and weather shifts. This is an exciting aspect of being in the mountains. On trips in June, snow is a possibility, and the rest of the summer rain is always a possibility on your trip. To be fully prepared, please follow the recommended clothing list closely (this list comes as part of your trip packet when you register). See below for average summer temperatures:
