backed by natural, untended land, which is generally conifer-deciduous forest. Both campgrounds host a number of RV-accessible lots. Electricity is also available to 130 campsites. All sites are located close to a source of running water, as well as a latrine or flush toilet. Comfort stations with washrooms, showers, and laundry facilities are available in each campground area. There are also radio-free areas, a visitor centre, and a gift shop/café. In addition, accommodation in heated yurts is available in the Sawmill Bay camping area, as well as a number of cabins, most of which are located on Bon Echo Lake, west of Highway 41. The yurts and cabins are an alternative to tenting or RVs, accommodating up to 5 or 6 and providing a more protected environment for less hardy visitors. Cutting and collecting firewood is prohibited on these sites to prevent environmental disturbances or damage. Firewood must be purchased at camp offices. Due to the emerald ash borer and other invasive species, moving firewood from regulated areas to non-regulated areas is not permitted without a movement certificate from the CFIA. Bon Echo is also known for its backcountry camping along the Abes and Essens Trail. This trail in the northern reaches of the park hosts five campsites, each equipped with a picnic table, stone firepit, and dedicated outdoor box privy ("thunderbox"). Unlike other areas of the park, none of these sites have access to treated water, electricity, or any other park service. Disturbing these sites is also discouraged, although the collecting of fallen deadwood for a campfire is tolerated if done carefully. Augmenting the ruggedness of the experience, Abes and Essens is regarded as a strenuous trail. The terrain is, in places, very rough and uneven, often with shield rock jutting up as on the Bruce Trail. Depending on the loops and paths one takes, the hike will take between 2 and 7 hours. The trail features three loops of , and , which intersect at various points, allowing navigation of the trail in many ways. The paths are not bold, preserving the ecology of the trail, and can be confusing at times, although the way is marked by flags on particularly difficult sections. Due to the length and difficulty of the trail, it is not recommended for the ill-prepared (or overpacked) camper, nor the unfit or inexperienced day-hiker. Other, less strenuous hiking trails include the Shield Trail and
