Hmm, take the trail to the Paradise Creek headwaters. Head east, bring rope, drop into Cony lake and follow the river out?
Trail to Fourth Lake, over Boulder Pass, stay in the green and head south, cross over Boundary just east of area marked as such, follow water down to SE corner of map.
As a 35+ year backpacker who doesn’t do rope I’ve found the areas where the elevation lines are widest are the way to go. Not the shortest, but less chance of becoming “cliffed out”. YMMV
