Europe and the United States are two continents that fiercely guarded their natural sights for the love of nature and mother earth. Although Europe have a lot of amazing must-see places, the United States and Canada have numerous national parks that is guaranteed to last you a lifetime. Unlike most places on earth where you basically feel like you've seen them all once you see one spot, For instance, when you think of Africa what do you expect to see? yah exactly. (not to take away anything from the majestic forests and jungles in Africa or the Southeast Asia though, sad thing is, they are not well-protected and deteriorating at a horrific phase). The United States is home to the most extreme and contrasting weather conditions which helped shaped the land differently, that is why there are always something new to expect in each state. The United States Gov't granted free passes on selected holidays.
Some of the must-see are the worlds tallest tress. The tallest giant redwood tree to date is named "Hyperion" by Prof. Steve Sellet, it is measured at 379.1ft. tall! giant tress like these can be found in Redwood National Parks, the park is one of the world's remaining majestic forests with two major rivers and 40 miles of wild coastlines that extended from the North coast in California to Oregon, USA which is often visited by the Gray whales. The forest supports a variety of trees and home to the great black bears and other endangered species. There are four camping grounds in the park, 3 inside the redwood forest and 1 in the coastlines. Most campers use RVs so you don't have to worry about accommodations, the park's employees are available 24 hours a day to attend to your needs. So, should you consider a wild adventure, it's good to come in your rented RVs if you don't have one over here. It gets you there comfortably and you get to see more sights pretty easily. October to April is relatively difficult because of the snow, but generally, the temperature is between mid40's to below 60 degrees fahrenheit, but during the summer rich fogs covered the coast.
