"Looking at 7-10 day loop hikes in Washington for late August, I am wondering about a way to combine the Spider Meadow - Buck Creek loop with the Bath Lakes High Route (or any other spectacular long hike). I feel like my biggest obsticle is not having a great trail map of the area. I have searched for an embarrasingly long time without being able to figure this out myself. Can anyone point me in the right direction for a map, or offer any suggestions on a route?"
First of all, I commend you on your taste in routes. The Bath Lakes High Route is a Cascades classic that will test your stamina and resolve to the fullest to paraphrase the authors of the book, "Routes and Rocks, Hikers Guide to the North Cascades from Glacier Peak to Lake Chelan". It has been out of print for a long time now, but there is a used copy for sale on Amazon at the link below. This book is THE guide to off trail routes in the Glacier Peak Wilderness, and would be well worth the $59 the seller is asking, IMO. If you decide to buy it, be sure it includes the map set, which has most possible routes indicated. The biggest problem you will face is accessing the route. Normally, you start by ascending the Sulfur Mountain trail from the end of the Suiattle River Road, but it has been closed for nearly 8 years due to wash outa and Audobon Society legal objections to its repair on environmental grounds. The upshot is that the Sulfur Mountain trail has not been maintained during that entire period, and would present major obstacles to either ascending or descending it. I can tell you from years of experience that it is problematic after even 2 years of neglect. This means your only practical access to the route is from the east, and would require that you do the route as an out and back. This would be extremely challenging unless you a Killian Jornet analogue. Still, if you think you are up for it, get the book, study the routes required, and let me know if I can fill in any blanks. I can guarantee you it will be a hike you will remember for the rest of your life. in closing, word has it that the legal obstacles to repairing the suiattle River Road have been overcome, and that repairs will commence this year. If that proves true, and you can wait, I would strongly recommend that you wait until the road is repaired and preliminary maintenance of the Sulfur Mountain trail is complete before attempting the route. A good contact number to find out the status of the Suiattle River Road and the Sulfur Mountain trail is: Darrington Ranger Station 360-474-7324.
If I can be of any further help, post here or PM me, and I'll do my best.
