It's a hike guys. No worse than doing a hike in the summer. In fact in a lot of ways it's better. In the summer, when you hike up to some magical ravine, glade, mountain valley, you have to hike out. In the winter/spring, you get to slide out. Way quicker and easier.
Out of all my days snowboarding, very few resort days stick out in my head. The most rewarding days have always been in the back country. Some of them have been death Marches. 5-6 hours in, one run and done. Then again, when you are riding off of a 14k ft peak, it's something you don't forget. Most of my days riding in the bc during the season comprise of 3-6 runs. Hard work and sweat pays off with untracked pow and rides that people pay hundreds to thousands to have a snow cat or heli take them too.
I know Tuck's is popular and crowded in the spring, but the experience should be great. Snow shoes should be more than enough to get you back there. Pack a lunch, water, extra gloves, goggles, and some extra layers just in case stuff goes south and there is a rescue scenario. Otherwise I'm sure you'll have a blast. I've heard of people dragging kegs up there, so it's definitely not a 3 hour hike in. Probably more like an hour if you take it slow.
