There are several FREE places to park your car in Tahoe City. Note: There is NO parking at the River Ranch for rafters - so don't even waste your time.
64 Acres: the parking lot across from Bank of the West and next to the Bridgetender. This is the closest parking lot to the public launch. The access road is on Hwy 89S just south of the 'Y' after the Bridgetender. You will see a smallish brown sign on the side of the road that says 'Truckee River Access'.
From 64 Acres there is a footbridge which crosses the river so that you can easily get your raft, air, coolers, beer, ice and food at Savemart, Shell or Chevron on Hwy 89.
Next to the Chevron: Fairway Drive next to the Chevron gas
station has parking on one side of the street and is across the street
from where you will launch your raft.
"Beach" Parking lot on 89S: There is a small parking lot on the lake-side of 89 South just past the Bank of the West near the "Y" where you can park your car for free. There is also road-side parking along 89 South along this section on both sides of the highway and is close to the 64 Acres parking lot and Truckee River public launch access point.
