Bus from Cochamó to Lago Tagua Tagua leaves every day between 10 and 10:30 (coming from Pto. Montt). From there you hop directly onto the ferry and from the ferry you can take the next bus towards Segundo Coral (hop off anywhere you want, just let the driver know). I hot got off at "acceso Lago Azul" by Lago Totoral X {22-01} [25.0/187] and started hiking. The land owner charges (in my opinion illegally) 6k clp for access to the lake. Once up at the lake it depends on the wind if it's safe to paddle. I had low winds, was on the other side in ~2hrs. Camped at the beach S 41° 58.959', W 071° 50.706'.

Hiked the short section to Lago Las Rocas, strong tailwind already in the morning. Reached Carabineros at noon (they're open till 8pm), no Salvoconducto needed. They email PDI and get a reply before he finishes filling out the paperwork. Camping between borders is an option (around 2kms after Chilean border post) needs to be communicated with Carabineros. Paddling Lagos Inferior and Puelo is also no problemallowed. I opted to hike until Lake {22S} [26.8/213], because of too strong winds on Lago Inferior. Lago Puelo is a little sheltered in the beginning, no problem paddling until Argentinian border post (open 8am till 8pm). Immigration no problem, camped there.
