Cable Bay is one of the main attractions north of Nelson, and we were impressed. The guides were fun and accommodating on the quad bike riding, thanks guys.
Then the Skywire ride is pretty cool and in a unique setting. If you are looking to really scare yourself, sure, go elsewhere and do a bungy jump. But for an exhilarating ride in a very scenic setting, and with few adrenaline rides you can do as a group of 4 ,this was pretty good. Tip - take the goggles as offered! (wind on the Skywire, dust on the quads).
Only downside we felt was that it is top-end pricing, might deter people from return visits perhaps.
