SNOWPEAK

I take it you are talking about the mountain trail on the way to snowpeak. Just morph to a wolf and hit the sense button and follow the trail. From time to time you can morph back to human and look around or solve a problem. Snowpeak is fun so enjoy your visit there. If you need further help just ask....Good luck

Well you have to get the picture from ashel then show it to prince Ralis in Kakariko he is at the zora resting place hell give you his earing so that you can catch a reek fish near the mother and child rocks meaning two rocks beside each other one bigger then the other they will be in zoras domain just in front of the waterfall once you catch one turn into a wolf put your senses on then smell the fish you will get a reekfish scent wich if you turn on will lead you through the snowstorm at one point you wont really need to follow it but if it's your first time goin through I would reccomend you keep using and just an extra little tip starting around snowpeak the howling stones get challenging don't do it all at once start by doing it bit by bit

Ok, you need to get the Coral EarRing from Prince Ralis, if you don't know how to get it, Get the Picture from Ashel right as you enter the area, Prince Ralis is at the Place where his Mother Gave you the Zora Armor, show him the picture and he'll talk to you about a Reekfish, (Ashel called it a red fish), Warp to Zora's Domain and go down the water fall and go to the land to your left, fish for a couple of reek fish then transform into Wolf Link, sniff the scent and forget the old scent, then go back up to the Mountain trail and turn on your sences (as Wolf Link of course), follow them till you get through 2 doors with big hand prints on them, then turn off sences and transform into Human Link, go up and talk to Yeto (big guy with Huge tail thing) he'll hit the tree and slide down a kinda long trail, roll into the Tree and then get on the Ice Shard you knocked down, Ride all the way till you get to a Big Mansion, Hope this helps you...
