- Sam Mc Eachern from New Zealand writes:
NZ's best kept secret. If you like to get away from the groomers and are prepared to go on short walks, Rainbow will be very good to you. Requirements to enjoy Rainbow: if you're a snowboarder, have an old board with you, if the rocks are showing you can still get freshies all day. Skiers, to have as much fun as the boarders you will need to be comfy with powder and same advice re your skis, skins would be a big advantage to take you up the big hill - 6:1. Never an unhappy face in Rainbow and the road's good. Chains are essential most of the time even if you have a "Big horn".
