Federal Aviation Administration regulations prohibit carrying fuel in containers such as stoves on commercial airlines. Footwear Boots should be a sturdy hiking or mountaineering type that provides good ankle support. Some hikers prefer boots with the rubber shoe and leather upper, like the Maine Hunting Shoe. You can count on your feet getting wet regardless of your boot type, so durability and support should be a prime concern. Many pair of socks are essential.
Tennis shoes are good for crossing rivers.
Insects Insect repellent and head nets are highly recommended. Rain gear and clothing Durable rain gear that covers both the upper and lower torso is a must for hikes of any length. The rain gear should keep out water in a steady down pour. Since you will eventually get wet in any significant rain storm, wool or synthetic clothing that insulates when wet is highly recommended for wear under rain gear.
