Just a note to stay in touch with mountains like this that do not get the attention others do. The road from the Tomyhoi Trail to Twin Lakes is impossible by vehicle. There has been no maintenance this year up to this date. There are washouts 3 feet deep, trees on road and bank sloughs covering road. Plan to hike the extra two miles to Twin Lakes to start.
This year the road is in much better condition. I didn't brave it but saw a number of sedans at Twin Lakes. Expect to bottom out with a low clearance vehicle but I would say its very drivable to most.
