The track to Roy's Peak is just a very short drive, bike ride, or hitchhike from Wanaka town center. The trail is basically a long boring series of switch backs all the way up an awesome photo spot/campsite. Then, it goes straight up, until you reach the Summit of Roy's Peak (3hr - Hard), which has more options for camp sites. Since we wanted to get photos of the sunrise, sunset, and astro shots, we decided it would be best to carry in our camping gear. The trail is not very exciting or easy on the ascent. Carrying my shitty camping gear, plus camera equipment, didn't make the trail any easier. The views are worth it and it was an amazing experience.
There is only one toilet a few meters up the track, so come prepared. Camping is prohibited. So, camp at your own risk. In the busy season, expect people to be walking up basically all night. Also, don't be surprised if you hear a crew 18 year old Germans boys bumping 50-Cent at 4am. Whether you do it for a day hike, a 3am sunrise hike, or an over-nighter, it should definitely be something you check out while in the Wanaka area.
