It is not uncommon to pass only a few, if any, fellow hikers as you make your way up the hills north of town. Although most backwoods explorers prefer this isolation, the downside is if you are injured, there may not be any potential rescuers along for some time. Hiking is a relatively low risk sport. Still, it is wise to educate yourself as to potential hazards and to know how to deal with emergencies should the worst arise. Carry lots of water and drink it as you go.
Visitors recently arriving at altitude are already prone to dehydration.
Add a hot day and a long hike and you create a real danger of health threatening dehydration or heat stroke. Also, your body needs water to operate correctly. If you are hiking as a way to become more fit, don't handicap yourself by not drinking sufficient fluids. Wear appropriate footwear. Shoes that won't give you blisters, adhere well to the trail, and have plenty of ankle support are a necessity for any well equipped hiker.
