Ruby valley and tsum valley? This topic has 0 replies, 1 voice, and was last updated 7 months, 3 weeks ago by Tory. Tory Mar 06 Hi. Anyone know if these two treks can be combined? Also, anyone have any suggestions for trekking routes that might work for trip with a two year old kid? Bit nervous of taking her above say 3200m so something lower altitude. Prefer to a avoid busy routes if possible. Did EBC and Gokyo the other year and loved Gokyo (without the kid though!). You must be logged in to reply to this topic.
