Spider Gap - Buck Creek Pass Loop is a 44 mile loop trail located near Leavenworth, WA. The trail is primarily used for hiking.
Spider meadow was amazing, but if you want a camp sight with a great view, stay at the knob just before climbing the glacier to the gap. Lyman lake also was wonderful. I recommend the side trip to image lake, you can't beat the sights, even the view from the toilet is great. Not much to see at buck Creek , but take the side trip to high pass, look outs to challenger glacier and triad lake are amazing.
The best backpacking trip I've ever done. Period. Make sure you take the side trip to image lake along the way, and I would encourage to spend a night there. Amazing scenery with so much to see. A week really wasn't long enough.
