The best time to visit Rocky Mountain National Park is in the summer or fall. Peak season is from July through mid August. The weather can be hot and stormy in summer, and it can be very windy and cold in the winter.
When planning your trip to Rocky Mountain National Park, it is important to remember to stay well hydrated, especially if you are coming from sea level. Altitude sickness can be quite unpleasant, causing mild headaches, disorientation, and severe vomiting.
To avoid a lot of traffic and long lines, it is a good idea to make reservations early. The park has a timed permit system that only allows a limited number of reservations for each day. This allows for easy parking and less crowds.
If you have limited time to explore Rocky Mountain National Park, you should start your hikes as early as possible. When you first arrive, take a short hike to acclimatize your body. Then schedule a more difficult hike for a later date.
If you're looking for a more scenic hike, take the Sprague Lake Trail. This trail is only a mile long, but has 36 feet of elevation.
You can also check out the Glacier Gorge Trail, which is 5.8 miles long. It passes Alberta Falls.
