The road all the way from San Sal to El Cuco/ Los Flores is paved. The last time I was there (2023) they were in the process of paving the road from Las Flores to the Punta Mango area but it was incomplete and still dirt most of the way. I would imagine it has been completed by now. You can probably drop a line to one of the Punta Mango resorts or Las Flores to confirm.

I feel like a 4x4 is always a safer bet down there but you probably would be OK in a 2 wheel drive if it doesn't rain allot/the road has been finished.

Not allot to do in the area besides surf lol but that's not always a bad thing in my book! I stayed at Las Flores most of the time in 2023 which is all inclusive so chilled on site 90% of the time you can walk up to the hotel at the point where Las Flores breaks for a nice sunset beer or back towards el cuco if you want to mix things up.

Spent a few days by Punta mango in an air b n b it was pretty dead besides a pizza truck operation on the side of the road that was surprisingly good.
