You can hike to most of the sidecountry spots (Peak 9 and Peak 6), but skins are easier (or so I understand). Of course, there is hike-to skiing inbounds off of the top of Peak 8 (Lake Chutes and Snow White) and Peak 7. The hike is short so hiking is probably far more efficient than skinning.
One word of caution: our snow pack is rotten, with a nasty hoar frost layer that makes everything quite susceptible to sliding. If you are headed out of bounds (Peak 6 or 9 and beyond), then you should have all the requisite equipment and training to use it, as well as a partner.
