When snow tubing do you have to walk back up the hill or is there like a towing mechanism that will bring u back to the top?

Going up hill is through rope and pulley operated. You just need to pull your tube to the staff on the loading area and they will hook up your tube to go up taking you :) enjoy the fun..stay safe

What Pradeep said ^^^ only thing is if your tube comes detached from the pulley mid-way up the hill, you'd need to walk up the rest of the way (only mentioning because it happened to my son the first time he went)
