01The Plan

A Weekend Built
Around the Pass

Two days, one mountain crest, and a rare open road. Here's why the timing works — and how the weekend breaks down.

Critical Seasonal Advantage

Tioga Road Opened May 15 — Exceptionally Early

Highway 120 East over Tioga Pass is open, giving us a direct line straight through Yosemite's high country to Highway 395 — cutting driving time roughly in half versus routing around the mountains.

Even better: Yosemite requires no day-use driving reservation this window, so we roll straight through the gates without a timed-entry hassle.

The Trans-Sierra
High Country

A 5 a.m. start beats the valley heat and the gate lines. From there it's all granite, alpine lakes, and a hard pivot into the high desert.

04Saturday Night · The Village

Dog-Friendly
Village Dinner

In late June the patios are fully open and Yoda's welcome on all of them. Every option below is steps from the Westin — no driving for the rest of the night.

05Sunday · June 21

High-Reward Vistas
& Route Selection

Same glorious morning in the Lakes Basin either way. The choice is how you drive home — backtrack the high country, or loop north over a fresh pass.

Early Checkout & Return via Tioga Pass

Pack up, grab the vistas and the Basin, then cross back over Tioga in peak afternoon light. Home to the East Bay by mid-to-late evening.

Late Checkout & Scenic Sonora Pass Loop

Sleep in, keep the room, run the same Basin morning — then check out late and loop home north on 395 and west over the 9,624-ft Sonora crest, dodging all Yosemite gridlock.

06Sunday Split-Track · Lakes Basin

Two Trails,
One Trailhead

Park once at Lake George. The crew splits by appetite for elevation — then everyone reconverges at Horseshoe Lake for Yoda's big off-leash swim.

Track A · The Strenuous Scramble

Crystal Lake Trail

William & Matthew
45 min
Uphill push
Steep
Granite switchbacks
360°
Basin views up top

Starts directly from the Lake George trailhead — a steep, rewarding series of switchbacks up the granite cliffs. A real hiking challenge for William, sweeping views of the entire basin from above, and a fast descent back to the car.

Track B · The Leisurely Lake Path

Lake George · Mary · Horseshoe

Amelia, Layli & Yoda
Flat
Shoreline path
Shade
Massive pines
Calm
Water's-edge rest

A completely flat, peaceful walk along the forested shoreline paths — or just relax at the water's edge under the shade of the big pines.

Off-leash swim
Yoda's bonus: Drive 2 minutes to Horseshoe Lake, where dogs are legally permitted to swim off-leash — splash and play safely in the water.
