"Colorado is generally safe for travelers. Exercise normal precautions in cities. Be aware of your surroundings in downtown Denver at night, particularly around Colfax Avenue. When hiking or skiing, always check weather conditions, carry proper gear, and inform others of your plans. Mountain roads can be hazardous in winter; carry chains and check CDOT for road closures. Wildlife encounters (bears, mountain lions, moose) require caution; maintain distance and never feed animals. Common scams include fake parking attendants and ticket resellers at events. Drink plenty of water to avoid dehydration at high altitudes. Colorado's legal cannabis industry requires responsible consumption; public use is illegal, and driving under the influence carries severe penalties."

Entry and health

Health information

"Colorado has excellent medical facilities, particularly in Denver, Colorado Springs, and Boulder. Altitude sickness is a common concern for visitors to mountain areas above 8,000 feet; allow time for acclimatization, stay hydrated, and avoid alcohol initially. Sun protection is crucial due to high elevation and intense UV radiation. Tick-borne illnesses (Lyme disease, Colorado tick fever) occur in rural areas; use insect repellent. Ensure you have comprehensive travel health insurance as U.S. medical costs are extremely high. No special vaccinations are required beyond routine immunizations. For emergencies, major hospitals include UCHealth University of Colorado Hospital (Denver) and Penrose-St. Francis Health Services (Colorado Springs)."

Culture

Local customs

"Coloradoans are generally friendly and outdoors-oriented. Casual attire is acceptable in most settings, though upscale restaurants in Aspen or Denver may require smart casual wear. Tipping 15-20% at restaurants and for services is standard. Respect trail etiquette: yield to uphill hikers, pack out trash, and keep dogs leashed. The state has a strong craft beer culture; brewery tours are popular. Cannabis is legal for adults 21+ but consumption is restricted to private property. Be mindful of fire restrictions, especially during dry summer months."
