Take alot of water,.. even in mid-May this was a dry "summer" hike.
A great 3 hour venture though it would be nice if you didn't have to walk so far across vineyards just to get to the trailhead.
Nice terrain, a stop by a nice lake, and a decent view over the Oliver area.
Add this one to your Okanagan sidetrip list. I'd do it again if in the area.
