EMMA’S TRIP NOTES / YELLOWSTONE
UPPER BASIN → NORRIS + MAMMOTH → CANYON + LAKE → LAMAR

THE PLANNING IDEA
Yellowstone’s famous places sit across a large road system. Give each day one geographic cluster and one backup inside that cluster; when traffic or weather wins, cut the farthest branch.
TRIP AT A GLANCE
DAY 1
Upper Basin
Old Faithful, basin boardwalks and Grand Prismatic as one western thermal day.
DAY 2
Norris + Mammoth
Pair dynamic geysers with travertine terraces.
DAYS 3–4
Canyon + Wildlife
Build an east-side Canyon/Hayden day and a north/Lamar day.
THE DECISION

OLD FAITHFUL + UPPER BASIN
Western thermal day
Walk the basin and use predictions without chasing every eruption.

NORRIS + MAMMOTH
Northwestern contrast
Reverse the order when Norris parking is full.

CANYON + HAYDEN
East-side anchor
Protect Lower Falls; let wildlife replace the extra lake stop.
LAMAR + NORTH
Wildlife day
Choose only when your base makes dawn or dusk realistic.

A sighting can absorb an hour. Let it replace a secondary stop, maintain legal distance and never create a new hazard in the travel lane.
WHERE TO STAY
Lodging is routing infrastructure. A central or split-base plan can save more time than a prettier room outside the wrong entrance.
GETTING AROUND
Verify every road segment. Build one cluster per day and assume construction, weather or wildlife traffic will consume part of the margin.
CURRENT PLANNING NOTE · VERIFIED AUGUST 18, 2026
Projected 2026 road and facility dates remain weather-dependent. Parkwide chip sealing can add delays, and thermal or wildlife closures can change quickly.
