Trekking through the rolling hills of the Eldorado Mountains between Boulder City and Bullhead City, Nelson Roller Coaster is a heart-pumping offroad trail that features scenic views and non-stop adventure as you rise and fall and twist and turn through the remote landscape of southern Nevada. Aptly named, this trail takes you on a desert thrill ride through countless steep climbs and descents that will almost make you nauseous. Combine this short trail with numerous other trails in the area and enjoy an entire day exploring gold mining history dating back to 1775, when Spaniards originally discovered gold in these very hills.
