Planning Your National Parks Trip
Choosing the Best Time of Year
Spring and fall are generally regarded as the best seasons, but every park has its peak season and has certain climatic conditions acting as considerations. Typically, one can expect a spring or fall visit to be mild in terms of weather and not very demanding in terms of the crowd, while in summer, it can become a busy time. On the other hand, winter visits permit involvement in ski and other snow activities in parks such as Yellowstone and Yosemite. This presents the need to become cold-proof before attempting such visits.
Accommodation Options:
- Camping: Most parks offer camping facilities, some that can be booked in advance. During peak seasons, people are requested to book in advance since the favored camps are very busy.
- Lodges and Cabins: Lodges located on the spot are convenient, offering a wide range of services, though they experience high levels of booking even 3-4 months before.
- Nearby Towns: If lodges are fully occupied, people can stay in neighboring towns outside the park, where more entertainment options are available. It is, however, necessary to commute to the park every day.
Transportation and Routes
- Driving by oneself is the best way to get to and explore nature and national parks, especially, vast parts of them more flexible free-time plans.
- Shuttles are available in various parks like the Zion National Park and Yosemite National Park during rush hour seasons may reduce the traffic load.
- During the time that pubic transits do not offer good services, personal car hire is the recommended means of transportation.
