The Robinson and Golden Trout Lakes trails are infrequently maintained and strenuous. Afternoon thunderstorms are common. Snowstorms may occur at anytime. An ice axe may be needed in early season. So it's a good idea to carry some along.
Giardiasis is a serious problem.
Boil or filter all drinking water. The Kearsarge Pass trail and many parts of Kings Canyon National Park are as popular with bears as they are with people. Food storage facilities have been installed in some backcountry locations where storage in trees may be ineffective. Check at the Ranger Station before starting your trip for current information on bear activity. Piped water, flush toilets.
