Family vacations are hard. It's hard to plan for every contingency, it's hard to find somewhere that everyone will like, and it's hard to find places to stay even before you get there. However, Yosemite National Park (nps.gov/yose/) is more than capable of helping you make it easy on all levels.
The Yosemite National Park has been on the maps officially since 1890, when the land was set aside by the governmental decree. However, some of its landmark and features have been around far much longer than that. The park features sequoias, some of the planet's oldest (and tallest!) plants. It's also on top of some of the oldest active volcanic activity, even if that activity is limited to hot springs and geysers. Speaking of geysers, it is home to one the world's most famous, Old Faithful.
The park's volcanic features are just part of its highlights. Because it is also a nature refuge, it is also home to a number of endangered plant and animal species, most notably wolves, bears, and bighorn sheep, but it also features rare plants and animals. A hike through the park can be an interesting travel, as it can cover five entirely different terrains, even over short hikes.
Yosemite National Park has a fascinating human side as well, as it has been used by two-legged mammals for eons. Settlers traveled through the lands that became the park on the way to California and Oregon, and Native Americans followed the game there for centuries before that. Both groups left a number of artifacts as they passed through over the millennia.
The park features a number of tours, planned and self. There are a number of tours each day, led by rangers and tour guides, that go throughout the park. There are also self-guided tours of some sections of the park. Some features (such as Old Faithful) even make their own stops. There are trails, roads, and campgrounds throughout the park so that the park can be explored and hiked through at an explorer's own pace. There is even a museum, with short trails nearby.
Although Yosemite National Park is well-known for its natural features, hiking, and campgrounds, its hotels aren't. Although most people stay in campgrounds, some do prefer to stay in a hotel. Yosemite National Parks have plenty of them.
DNC Parks & Resorts operates a number of lodges and hotels in the park. There is even a strait-forward hotel, Yosemite National Park's nicest place to bed down. Built in 1927, The Ahwahnee has everything that one could wish for from a hotel in the Yosemite National Park: great views, private meeting rooms, and even a mural of the park's sights. The hotel is AAA-rated. However, be advised that reservations are a mandatory.
In short, Yosemite National Park has a lot of features combining the wild and the civilized (mostly wild) into one great place for your family to visit. As usual, remember to plan ahead to maximize your fun and minimize your labor while there, but don't be afraid to improvise. Enjoy the trip into the woods, and remember to not feed the bears!
