The Wonderland Trail (WT) is 93 miles (150kms) long and encircles Mount Rainier. It is a strenuous hike with lots of elevation gain and loss, through lowland forests and valleys and into high alpine and sub-alpine areas. Perhaps the biggest aspect in planning to hike the Wonderland Trail is you knowing your hiking skills, abilities and habits. Rangers cannot tell you that. Nobody knows your skill level better than you. This is important when laying the foundation for your trip... selecting the proper distance between campsites. Do you live and hike primarily in mountainous terrain and climates, or lower elevation areas? Hiking on flat terrain for 93 miles is far easier than having to climb up three thousand feet with a full pack day, after day, after day. This sounds like something that should not have to be stated, but we often see hikers going beyond their skill level. This usually leads to injury, illness, misery and an early end to a long-planned trip.
