On Saturday, I took my bike up Route 2, kind of playing it by ear. There turns out to be a highway rest stop about 15 miles east of Steven's Pass. Signs in the parking lot ask you not to stay more than 8 hours, which is more than enough for a great ride. They were giving out free coffee, with actual humans working there, so I asked if I'd get towed if I left my car there and went for a bike ride. Nobody was willing to actually give me permission, but they said it probably wouldn't be a problem...
I rode up the mountain, until the point where the road divides, like a freeway. People are still skiing at the pass. There's a lot of snow. The speed limit is 60 mph before the road divides, and it doesn't change, but the split tells drivers that it's ok to go much faster. Shoulders are as narrow as they could be. I'd really like to cover this ground, but it'd be a really bad idea before the snow melts (and just a regular bad idea afterwards). So I turned back. I wanted to do more exploring, though, so I passed the car, and turned left at highway 207, at the little town of Coles Corner, after stopping at the one diner for an iced cream shake. About four or five miles down the road is Lake Wenatchee, which turns out to be starkly beautiful.
I'm not sure how this is possible, but maybe the roads were designed by MC Escher. Route 207 was down hill both ways.
This came to 38 miles, with about 2,200 feet of elevation gain. It's a very easy route to follow, and, if you have a map, there are a few opportunities to explore and make a longer ride. Highly recommended.
If you want to read more about it, I wrote up a blog post called Beyond the Cascade Crest about the trip. Honestly, though, you should just take your bike up here instead.
