Mammoth Lakes 2022

JULY 13-17, 2022

Our July Bus Trip features a number of trips in Inyo National Forest near Mammoth Lakes. Inyo National Forest takes its name from a Native American word meaning, “Dwelling Place of the Great Spirit,” and you can see why it would choose this location. It is home to expansive clear skies, crystal blue mountain lakes and streams, majestic mountain peaks, green meadows awash with flowers, and unbelievably beautiful views.
We will be offering a base camp with dayhikes as well as four backpacking trips of varying degrees of difficulty. We will travel in a chartered, air-conditioned bus. Participants must provide their own meals and camping equipment. Please check the information under the resources tab for more information about what to bring. Upon registration, you will receive an email confirmation and information about an optional pre-trip meeting to meet your leaders and ask questions (highly recommended for first-timers). A hand-out will also be available with suggestions about what to pack, weather, safety tips, etc. Please check out the documents found under the Resources Tab for more information.

Trip 1 
Type of Trip:  Campground Basecamp
Name of Trip: Base Camp / Day Hikes
Leader: Karen Nelson   Assistant Leader: Ruben Garcia
Trip Rating: Moderate
Event capacity: 10

Our group camp is at the New Shady Rest campground, close to the Mammoth Lakes Visitor Center and free shuttle bus service within the surrounding area. Our day hike format will allow us to sample some of the most beautiful destinations in the area, while stopping for dinner in Mammoth on the way back to camp as an option. Our campground includes potable water, flush toilets, fire pits, and bear lockers.  The campsites are adequate for small tents, so larger tents are not allowed unless you are sharing. Campers are responsible to bring their own equipment (daypack, tents, sleeping bags, stove…), as well as food for four days (four breakfasts, four lunches, four dinners, trail snacks).

This trip is intended for hikers who are fit, have had recent experience at higher altitudes, and want to explore the area by hiking each day. Depending on trail/weather conditions and group interest, our hiking options include two hikes in the Mammoth area and a spectacular hike near Bishop. We will hike at a moderate pace on well-used trails, with ample stops for snacks, lunch and enjoying our surroundings. 

Long Lake via Little Lakes Valley Trail (M7B)
Located south of Mammoth near Rock Creek, the easy access to this beautiful chain of lakes makes Little Lakes Valley popular for day hikes. Glaciers carved this extensive chain of lakes, both large and small. Wildflowers bloom in the high elevation framed by the spectacular 13,000-foot peaks of Bear Creek Spire, Mt. Dade, Mt. Abbot and Mt.Mills.  Some evidence of mining equipment can be seen. 

Lower Falls via Devils Postpile (M6B)
We will take a shuttle Reds Meadow and the Devils Postpile National Monument. A main feature of Devils Postpile National Monument is Rainbow Falls, where the Middle Fork of the San Joaquin River tumbles 100 feet over a basalt cliff in a vertical-walled - a delicate sheet cascade in fall, when the water splits into separate streams, or a raging torrent during the peak snowmelt season of early summer. Further downstream, outside the monument, is the smaller, but prettier Lower Falls, a 15 foot drop over a smooth granite rock face.

Barney Lake Trail (M6C)
Just outside of Mammoth Village, we will escape the chaos of the city and venture to Barney Lake, a well-trafficked but pristine hike that is just challenging enough to get your heart rate moving and takes you deep into the Sierras. Sitting just below Duck Pass, you will be rewarded with a high alpine lake and mountains jutting up out of the water high into the sky.


Trip 2
Type of Trip: Base Camp 
Name of Trip: Barney Lake Base Camp
Leader: PJ Jeffery  Assistant: Monica Elrod
Trip Rating: (MC3)
Event capacity: 7
Number of Backpack Days: 2, Number of Backpack Miles: 6, Number of Day Hike Miles: 20+

This trip involves a short backpack but longer dayhikes which could include some cross-country travel.  Participants should be comfortable hiking 10+ miles a day at or above 10,000 feet.  We will start our trip by hiking up the Duck Pass Trail (9,128'); climbing moderately steep switchbacks through a lodgepole pine forest for about a mile until arriving at our first lake - Arrowhead.   We continue our climb with views of Mammoth Crest ahead of us, passing Skelton Lake (9,924') and the trail to Red Lake before arriving at our camping location - the beautiful turquoise, Barney Lake (10,210').  After setting up camp, we will go back and explore the lakes in the area with daypacks.  On Friday and Saturday we will hike further afield with possible trips to Duck Lake (at 222 acres, it is one of the largest natural lakes in the eastern Sierras), Pika Lake, Purple Lake, and Deer Lakes.  We will have amazing views of Mammoth Mountain, the Minarets, stunning Silver Peak, and the Silver Divide.  Sunday we return to the trailhead.  We might take an alternate loop around Emerald Lake.

Backpack along the Mammoth Crest from Lake George to Deer Lakes.  The trail climbs 2000' through forests, then stays on the ridge top.  The views are magnificent in all direction.  At the highest, 11,223", we look down on the summit of Mammoth Mountain.  The three lakes are surrounded by granite peaks in an otherwise volcanic area.  The optional day hikes will explore the area, including a cross country hike to Duck Pass.  If that route is not difficult, we may return to the shuttle bus via the Duck Pass Trail.

Hiking bloggers say that this area tops their list for the most amazing scenery: deep blue lakes, starry night skies, and the mountains including the Peaks of Mt Ritter, Banner, and the Minarets provide a beautiful backdrop. We start our 4-day backpacking journey at Agnew Meadows and head to Shadow Lake for a well-deserved lunch break and perhaps some swimming. We then continue along the Shadow Creek Trail to Ediza Lake for a 2-night stay. On the second day of our journey, we will do an optional day-hike to Cecile Lake and possibly beyond, we can go as far as our hearts desire and our energy allows. On day 3, we will backpack to the stunning Thousand Island Lake and spend our last night there.  On our last day, we hike out on the scenic “High Trail” back to Agnew Meadows and return to civilization.
