What are the opening hours for Yellowstone national park?

Answer 1

Very few national parks actually close. One exception is PetrifiedForest because folks cant help themselves from taking petrified wood. Most national parks that are natural actually allow you to stay in the park. Historical parks however have given hours.

Answer 2

Like almost all national parks, Yosemite is open to visitors 24 hours a day, 365 days a year. Yosemite Valley, in particular, never closes and is very popular in winter.

The road over Tioga Pass closes after the first major snowfall and does not open until the road is cleared. The latter can be as early as April 29 and as late as July 1.

Answer 3

Like almost all national parks, Yellowstone is open 24 hours a day, 365 days a year.

Roads close in the winter for safety reasons, and facilities close as fewer visitors come. But anyone who pays for or obtains an admission can enter the park at any time.
