Mike,
I spend about 20 weekends a year in Truckee and I’ve got to tell you, the 4th of July is ugly around the lake. Leaave VERY early if you plan to to the lake rim ride, too many people with cousin Fred’s motohome, who are learning how to drive it for the first time today, are out there. To be safe, take the advice of going over to Carson City and riding out there. If you are looking for a good hill climb, mount Rose is great.
Also, you are going to be in Mountain Biking Heaven and you want to road bike? Sounds nuts to me. I’d be renting a free ride bike and going ball out on the trails. Better yet take a day off and go to Northstar at Tahoe and rent a downhill bike and get a trail pass. Nothing compares to 40 miles per hour down ski runs on a bomber bike for thrills! They have sweet trails set up with jumps and everything.
If you are at the North side of the lake, stop in Carneilain Bay at the post office cafe for breakfast, it’s a great place to load up before a full day of riding. Take a trail run at South shore to fallen leaf lake area and pull up to the Rubicon Trail. An agressive mountain bike ride up ther Rubicon will put you at Spider Lake where you will be required to stop and do some of the best fisshing you have had in your life!
There is an outdoor pool at Tahoe Donner, day use fees apply and it can get crowded after 9:00 AM.
Nice Trail running out of Spooner Lake area near the UC research station. Fire roads, but very nice too.
The pacific Crest trail runs right by Donner summit on HWY 80. The trail running up there is great and it’s 7000+ feet so it’s a lung buster. My dogs and I run up there often.
I second the thought of doing the flume trail, but then again it’s a lot more fun to do on a mountain bike than running because if you run it you will be dodging yahoos on mountain bikes all day. If you decide to run it, do it uphill so you can see the buggers coming at you!
The lake is cold, bring your wetsuit if you plan on swimming in it. Donner lake is only marginally warmer due to the tremendous snowpack of this year. In fact be prpared for colder than usual nights. It’s been into the 30’s in the past few weeks and even snowed only 10 days ago in the high country.
About 20 minutes south of the South shore of Tahoe is upper and lower Blue Lakes. Trails from Upper Blue will take you back into some beatutiful places with not many people.
Have a great time, I’ll be painting the house and repairing a sprinkler system (oh joy)
Cheers, Karma
