Absolutely essential and delightful, we stayed at "just the right" campground many times with this app. Between this, a campervan, and the DOC booklet, we could always find everything. Kudos to NZ for putting together such a great info source, wish we had something as great and useful for the U.S. Double bonus- all the info is still available offline.
