Do a search on the camping board and you'll get some directions on how to get there. If you have a car - I would recommend using that instead of buses. We attempted getting there last year and it can be quite an ordeal using buses (we had to go from POP to MK to boat to WL and then FW, then walk to the internal FW bus stop - then hop a bus to the location). We never made it because we didn't anticipate how long it was going to take.
But we're going to try again in a month when we're back! I really think our kids will love it!
