Yet another vote for the Florida Trail. Cannibal's right about the banana spiders
, but they should be at about the end of their life cycle most places right now (they're not really dangerously venomous to humans; they're just ugly, huge, and annoying when they bite). By next month or January, the majority of 'em will have died off until March or so.
Most folks finish the FT in three or four months, but if you're a fast hiker, you could probably do it in two to two and an half (20-30 mile days). Most of FL is flat, but don't let that fool you. There're enough poor blazes in places down here to slow you down to map and compass time, the vegetation is no joke (saw palmetto sucks
), sugar sand'll tire you down faster than rock hopping, swamps can be less than fun, and you have to be careful about your water planning. Still, it's a fun time. Challenging, but fun. Expect temperatures ranging from ~20* F at the lowest to ~80* F at the highest this time of year, depending on where you are on the trail and what the weather's doing (if you don't like it, sit down and have a beer: by the time you're done...).
the official FTA website.
our very own lilricky's unofficial GPS data page for the trail.
a website with many individual experiences about the trail.
I've, personally, done the Ocala South portion of the trail. If you want/need advice about that section (~45 miles), feel free to PM me.
Hope it helps!
