Essential Travel Tips
Book your timed entry reservation to Rocky Mountain National Park well in advance, especially if visiting during peak season (June-August). Traffic can be brutal, and reservations guarantee access. Consider using the park's free shuttle system once inside to avoid parking hassles and enjoy the scenery.
Pack plenty of snacks and water; prices inside the park are significantly higher than in nearby towns like Estes Park. Consider purchasing a reusable water bottle to fill up at the many water sources within the park to save money and reduce plastic waste.
Altitude sickness is a real concern. Take it easy on your first day, drink lots of water, and avoid strenuous activity. Download the Gaia GPS app for offline maps and trail information – cell service can be spotty in the mountains.
Respect wildlife by keeping a safe distance and never feeding animals. Learn about the park's history and ecology before your visit – it enhances the experience and helps you appreciate the area's unique ecosystem. Many ranger programs are available for free.
Estes Park, just outside the park's entrance, has many excellent restaurants with varied price points. Try a local brewery for a taste of Colorado craft beer. Pack a picnic lunch to enjoy amidst the stunning scenery, saving money and time.
Layers are essential! Weather in the mountains can change rapidly. Pack waterproof and windproof outerwear, even in summer. Sturdy hiking boots are a must, and don't forget sunscreen, sunglasses, and a hat for sun protection.
