We are going in August and taking alot of tours. We are not big hikers and I believe most of the trails I looked into are less than two miles around trip.

I know that the mornings and nights can get cold. We are taking an evening raft trip and an evening wildlife tour...so what are we talking sweat shirts or coats?

Also during the day should we be wearing shorts or long pants.

And my biggest question.....foot wear. We do not own hiking boots and I would prefer not only not to have to spend money to buy them, but also don't want to have to pack them since they are so heavy. So my question to anyone that has gone is can we buy a walking or hiking type of sneaker that will be OK for those short/ easy trails? Do you think we will be OK with something like that? My other question is does anyone have any suggestions on a brand?
