Hello, I was wondering if it's possible to hike and camp the following volcanoes without a guide or tour;

1. Maderas in Ometepe
2. Telica
3. El Hoyo(I asked a tour if i could split off my own after volcano boarding Cerro Negro and they said no, ofc they do offer camping on El Hoyo)

I am bringing a tent a sleep system(all compact, fits in 1 bag) on my trip and want to make it worth carrying all of this around. If you know of any spots that i could do some wild camping along or close to this route please let me know. Ometepe - Leon - El Tunco - Santa Ana.

Thank you
