There’s a garage (paid of course) on Virginia. It’s north of the Century Theater, across a small side street from it.

Sorry just saw this, Ginny. Hope you found it ok

Although I didn't see any public restrooms, the restaurants along the river had no problem allowing people that needed to use their restrooms.

I also stayed at the El Dorado. It is about 4 blocks to the Truckee River Walk. It is a paved, level trail, head up river to get to Idlewilde park where you will find the Nevada State Law Enforcement Memorial and the Reno Rose Gardens. It is about 1 mile to this park. The trail continues on past the park for probably another mile if you are inclined to go farther. So the walk from the El Dorado to Idlewilde Park is a little over 2 miles round trip. There is a really nice Cinema on the River Walk and there is a section of created whitewater recreation where kayaks practice. The river should be pretty high right now, it will be a fun walk. Check out the Reno Botanical Gardens and Museum too, they are just past the University of Nevada. Also about a 1 mile walk on city streets, mostly uphill.

Yes it is! Just a few blocks away!

I did not see an no fishing signs. Check on the Nevada Department of Fish and Game to see if it is open and the price for non-resident licenses.

Tom, I have never seen anyone fishing in this area. it is used for swimming, wading and kayaking. Fly fishing is a frequent activity a few miles west on the Truckee River though.

Leave car at Silver Legacy and walk to river. I think heading East along river has more running / biking paths but not sure. Ask locally.

It won't be too cold to walk around the Riverwalk unless there is a blizzard. Check the weather reports to be sure that it is OK. It is best to walk there in the afternoons during December, the warmest part of the day. There are lots of fine places to stop for hot beverages and food, and interesting places to look at both inside and out. It is not walking distance from The Peppermill though. You will have to take a car, Uber, taxi or bus. Check out the site for Reno Riverwalk. I can't give url's here.

It's pretty far, but straight up Virginia Street. I know people who have walked it, but not me. I would grab a cab, Uber or even the city bus ( I believe there is a bus route up and down Virginia). The River Walk is super convenient to the "downtown" area. I would plan some time to be downtown-- checking out the casinos and doing the River Walk at the same time. All that said, Peppermill is my favorite -- the food at Oceano is my favorite!
