Heading to Amsterdam late June solo. Interested in some mudflat hiking. Will be using trains, likely staying in leeuwarden for a few nights. Any company recommendations? Which areas are more interesting? Thinking wildlife, natural beauty as pluses. Crowds and tourist traps are minuses. Might spend a night or two on one of the islands but I suspect prime time will make me rethink that due to availability and prices. Looking for maybe half day hike. Any thoughts?
