With "not too difficult" I`m thinking of something <800m elevation / <15km trip or <400m / <20. How crowded is West Coast Trail at that time?
Any other ideas?
West Coast Trail is going to be longer than that. It's 75km, not a ton of elevation, but it is fairly technical (ladders, mud, beaches, mud, cable cars, oh and more mud). It's a fantastic hike, but you're looking at 6-8 days to complete it (although strong hikers can do it in less). In July the trail will be reasonably crowded. For 2018 all spots are now reservable, so its going to be harder to get a walk up spot
