Water: assume none. The Forest Service page and recreation.gov contradict each other on drinking water here, so bring everything you plan to drink.
Timpooneke is where the north route up Timpanogos begins, and the campground sits at 7,400 feet rather than down in the canyon bottom, so nights run genuinely cold. Parking spurs are gravel, there are no hookups, and the Alpine Loop does not allow a vehicle and trailer over 30 feet, which keeps the big rigs out. Vault toilets and drinking water are provided. Reservable sites need booking at least five days ahead.
Tip: Summit-day base camp. Moose in the meadow most mornings.
Out the tent door: Mount Timpanogos (Timpooneke) (Hike, 0 mi) · Stewart Falls (Hike, 3 mi) · Manila Creek Pond (Fishing, 4 mi) · Battle Creek Falls (Hike, 6 mi)
