As of 8.10, we now have the Snowshoe activity in the I2S, but I've noted limitations in its use and it needs some improvement, but I don't really know if this is a Connect problem or one that could be solved in-watch.
Ok, so with snowshoeing, it's not that one will snowshoe the entire way, but it will often be mixed between hiking/mountain climb, and snowshoeing. Now that we have multisport capability on the I2S (compared to the I1S), I use multisport to track the mountain climbing and snowshoeing because we go back and forth. Some also use skis for portions of the hikes in addition to snowshoes and spikes for climbing The problem is that when this displays combined in connect, it's largely a mess because it displays everything as "mountaineering". Could Garmin look into changing this in Connect or in a future watch update?
