Check trail maps at the visitor center before departing to distinguish between mountain biking and foot-traffic-only trails.
Dress in layers, as temperatures at the mountain summit are often significantly cooler and windier than in the surrounding valley.
Bring charcoal or firewood if planning to use the historic stone fireplaces, as wood gathering is restricted.
Do not attempt the more difficult mountain biking trails unless you have experience with rocky, technical terrain.
Some campgrounds and facilities are seasonal and close during the winter months.
Stay on marked trails to prevent erosion; pack out all trash; keep pets on a leash at all times.
