In Bishop, they stopped at Erick Schat's Bakkery.
Arriving in Mammoth, they did a little exploring.
A vacation wouldn't be complete without some time in the water.
Taking the shuttle from Mammoth Mountain, Ava visited Devil's Postpile and hiked up to the top.
Ava also saw the Mammoth earthquake fault, which is up to 10 feet wide and 60 feet deep.
At Hot Creek Hatchery, they raise about 3 million trout a year to supply the nearby lakes and streams.
She also saw some of the hot springs of the eastern Sierras.
Not far from Mammoth is ghost town of Bodie. Ava didn't see any ghosts but enjoyed the abandoned town.
From Bodie, Ava visited Mono Lake, and also earned her Junior Ranger badge at the Gateway to Yosemite.
Nearby, Ava ate at California's most famous gas station restaurant, the Whoa Nellie Deli.
One of the biggest attractions of the Mammoth Lakes area during the summer is, naturally, the lakes. Ava, Grammy, and Poppy spent loads of time at (and in) McLoud Lake and Horseshoe Lake, and surrounded by the natural beauty of the area.
After several days in Mammoth, Ava will be setting out through the Tioga Pass to head to Yosemite for the next stop on her adventure.
