Just to the east of town is a series of small mountains, such as San Gorgonio Mountain (the tallest mountain in southern California), Sugarloaf Mountain, and Butler Peak. Here, you can go skiing, typically from November to April, or you can go hiking in the warmer months. By hiking up to the top of these peaks, you will be rewarded with stunning views of the San Bernardino Valley below. Keep in mind, however, that these are fairly steep peaks, so be careful as you hike up. Of the popular ones, Keller Peak, Butler Peak, Delamar Peak, Bertha Peak are some of the easier ones to hike. If you want to feel as though you’ve stepped into another world, head east for about an hour and a half to the Joshua Tree National Park . You can stroll or hike among the bizarre Joshua Trees and as you travel deeper into the park you will begin to see how the two deserts, the Colorado and the Mojave, blur together. You can visit the unique geologic formations, be dazzled by the unique flora, and thanks to the lack of light pollution, you can look up and see the stars at night. What’s even better is that you can take your San Bernardino, CA RV rental, claim a campsite and enjoy the natural wonder of the desert. If you’re looking to go even further, or you want to get away from the deserts, you can take your San Bernardino RV rental by owner about four hours north of town to the Sequoia National Forest . You can hike your way through the towering sequoias that have become so famous or even go boating on the lakes. You can park and camp out in this remote wilderness and experience more of the beauty of California.
