Gulches is well worth camping, and spending a weekend. I suggest camping during early spring, or late fall. The weather can be relentless during the dead heat of summer. Be sure you reserve your camp site in advance, and check the Gulches site for any events going on at that time. In my opinion it's so packed during a holliday, or event that you can't have any fun. The trails are packed, and congested so bad it sucks. If you use the link in my signature you can keep up with the SC crowd, or use the gulches forum.
Our club has members all over the state, and we have several rides a year to gulches, and all over the south east.
