Plan & Prepare

Whether you are planning to travel the entire trail, or a particular leg, be sure you are very prepared. Bring clothing and gear for all weather conditions, as the terrain varies significantly and weather patterns can change quickly.

Dehydration is a very real danger, especially in high altitudes and hot temperatures. Drink plenty of water and have some with you at all times.

Always carry a first aid kit that includes a snake bite kit. You may encounter rattlesnakes along the trail in southern Idaho, so watch out for them and listen for their distinct rattle. Animals with their young, such as bears and moose, can be especially dangerous. Always be cautious and alert.

The best months for hiking this trail are May through September. You may encounter snow in the mountains, so plan your trip accordingly.
