You can begin your outdoor vacation by taking the best RV in Columbia across Susquehanna River to the 85-acre Samuel S. Lewis State Park. The park is open all year round from sunrise to sunset and offers stunning panoramic views from the top of Mount Pisgah, the highest point in the surrounding region. There is an arboretum which is home to English yew, European beech, fir, and more. When it comes to recreation, the main activities are hiking and picnicking. You can also pick up a sled and hit the hillside during the winter season. For something more adventurous, you can drive your Columbia RV rental farther west to Michaux State Forest. Known as the "Cradle of Forestry," this 85,500-acre forest crosses the borders of counties in Pennsylvania and hugs the slopes of South Mountain and the northern reaches of the Blue Ridge Mountains. The forest is primarily made up of mixed oak species, but you can also find a mixture of red maple, pine, black gum, and more. The forest offers a huge range of outdoor adventures from horse and ATV riding to mountain biking and snowmobiling. There are four miles of well-maintained cross-country ski routes as well as 60 miles of hiking trails, not including a 37-mile section of the world-famous Appalachian Trail. Even if you’re not prepared for an extreme adventure, you can take a picnic to the Old Forest Picnic Area, 4.5 miles south of South Mountain. Here, visitors can also make use of the athletic field and children’s playground. Next, you can take your travel trailer rental from Columbia south to Susquehannock State Park which is located on the lower stretches of the Susquehanna River. The 224-acre area is blessed with multiple scenic viewpoints such as Pinnacle Overlook, which offers views of Lake Aldred and access to Kelly’s Run Trail System. Hawks Point Overlook delivers views of Conowingo Reservoir and Mount Johnson Island, a sanctuary for bald eagles. Remember to pack the binoculars and leave some time to spot these majestic birds. Other recreational activities available within the park include hiking, horseback riding, and cross-country skiing. You can even take a picnic and make use of one of the many lakeside picnic pavilions.
