Novara Safari. The thing is a pig...weighs way too much

...but it is cheap and will do the job.
Of course a hardtail mountain bike with a fork lockout and a trailer would do the job too, with perhaps a little more flexibility if you want to set up a base camp and explore from there.
I got my ultimate off-road touring bike this last Christmas
But I doubt if you want to go that route. Even a 10 year old frame cost me $950. A new YBB costs north of $2800. Makes the stuff from Rivendell look cheap
