With such a wide diversity of trails to choose from, there is something for every hiker in the Vail Valley. From gentle-grade wanders through the woods to the intense and challenging summit of a "14er" (a mountain that peaks at 14,000+ feet in altitude), the world is your oyster as a hiker in the Vail Valley. Consider your fitness and comfort level with exertion before you hit the trail: at this altitude, dramatic increase in elevation will prove challenging and will, literally, take your breath away. Plan your trip wisely setting out early in the morning is always a good idea, as afternoon thunderstorms (though typically brief) can hamper your descent. Be sure to check with the U.S. Forrest Service for restrictions on certain terrain due to migration, fire danger or other reasons. Additional notes: Especially when hiking above tree line but a good idea on any trail is a solid hiking book. If you plan a longer hike or anywhere around water sources, look for waterproof "Gore-tex" boots. Ankle support is essential especially when navigating high-terrain boulder fields, a properly constructed and fitted boot can prevent a sprain. For more leisurely trails, a sturdy running shoe or a sneaker/hiking boot hybrid should suffice. See "What to Wear - What to Bring"
