We enjoy the hike to this classic alpine lake in the Pioneer Mountains for its diversity as well as its beauty. The hike begins with a refreshing wade across Wildhorse Creek, continues with a climb through the woods and a traverse through beautiful meadows, and ends with a steep scramble up the rocky wall below Boulder Lake. Be sure to bring wading shoes for the creek crossing.
Drive east on Sun Valley – Trail Creek Road for 22.5 miles to Copper Basin Road. Turn right and after 2 miles turn right again onto Wildhorse Road. Drive 5.5 miles to an informal camping area on the right and park. The sign beside the road indicates, “Boulder Cr. Tr.” Allow about 1 hour 10 min. driving time from Ketchum.
