We did this in November of 2015 from Echo Lake via the Bryce Path. There is one really steep section and when you get to the top you can go left for Whitehorse or right to Cathedral. We went left and came out to Whitehorse. The views were great but we didn’t get to hang out very long as we were losing sun (we started this hike too late). At the top in the back there is an entrance to an easier winding way back down and we took that. It ends up winding back and forth and then goes by the golf course by the White Mountain Hotel and comes out in the parking lot there. We cut across the golf course because it was really getting dark. We need to do this again and head over to Cathedral next time:)
