1. Granite Lake out of the Bay View TH, locating the trail is the hardest with snow cover, shouldn't need the 'shoes, snow should be hard in the AM. If you go beyond Granite, crampons would be nice if not required.
2. Closer to Fallen Leaf, take the Mt. Tallac Trail around the west/north side of Fallen Leaf all the way to just about the south end, check the map and where it shows the summer trail, you should be able to go up a gully there and be able to camp SSE of Tallac before it gets steep. Or locate the winter route out of one of those camps there, just north of the SnoPark less than a mile. I don't have my map with me, can't remember the little lake there along the way, sorry. We didn't stay there on a small group trip about 5 weeks ago. Where we camped, we had a pretty good view of Tahoe. We had cut uphill before we needed to and also after we should have. So now I know if I go again as the winter route stayed on a ridge above Floating Island. Might need 'shoes for part of this route when you start gaining elevation. I've been into the Velmas and Dicks Lakes a few times in the early Spring, no one stays back in there, just skiers bagging Dicks Peak. Hope my rambling helps.
