Originally built in 1936 (and with various renovations over the years), the Alpine Visitor Centre (open seasonably) is well worth a visit as part of your Rocky Mountain National Park experience. There’s an informative museum, large gift shop, café, and wonderfully panoramic views. There are also restrooms and staff on hand to answer any questions you might have.
If driving Trail Ridge Road or Old Fall River Road is on the top of your list and you have limited time, you may want to enter the park via the Fall River Entrance on the park’s east side. It also is just a few minutes from Estes Park’s downtown. You’ll reach Trail Ridge Road a lot faster than those waiting in line at the Beaver Meadows Entrance during the summer and fall seasons.
