Super relieved to be able to confirm after my visit that Hidden Lake was essentially unaffected by the Swann Lake fire. All the services (toilets, dump site, amphitheater, boat launch, campsites, etc) were not touched by the flames. However, from the lake shore (boat launch and day use area) there is visible fire damage so the fire came VERY VERY close. So if you intend to hike while in Skilak you'll likely want to go southerly, as we observed heavy fire damage from mile zero through mile 4. But the fire did jump all over the place so you may want to confirm with the park service if you have specific questions about trails or the back country. read more
