Is there a site full of cabins for people that is the age of 18+ for south lake tahoe? -

all the one that i have found is 21+

Since you are under 21, your best bet is to contact condo / cabin owners directly to see if they will rent to you. Renting a house or a condo would be a great idea, and there are a lot of choices for rentals in the Lake Tahoe area. It s best to do your homework and use online research to find available places to stay that fit within your budget.Rather than give you a specific property name and location, I would suggest that you do some research on the available houses/condos, the prices and the locations. I have used justvr.com in the past and it was quite helpful for narrowing down my choices and booking a few nights stay.
