A visit to New Zealand would be incomplete without witnessing the beauty of Lake Wanaka. For those that want incredible views without struggling up the difficult Royโs Peak Track, the Diamond Lake & Rocky Mountain Track has you covered.
This 7.3 km/4.5 mile trail offers incredible vistas over both Diamond Lake and Lake Wanaka, while being structured in a way that allows for greater freedom when deciding how to complete your route. Choose to visit Diamond Lake or continue onwards to the Rocky Mountain summit. We can guarantee that this will be a trail to remember.
About the Hike
The Diamond Lake & Rocky Mountain Track is one of the top trails near Wanaka. The full trail is a combination of several smaller routes that converge together into a figure-8 shape. This trail structure gives you a lot of freedom on what you want to see, as there are spectacular views every step of the way.
On the way up to the Rocky Mountain summit, hikers will pass both Diamond Lake and the Lake Wanaka viewpoint. Each viewpoint acts as a great potential turnaround point if interested in completing a shorter route.
The views along the trail are stunning, and given the moderate level of difficulty, itโs no surprise how this hike is one of the best.
The stats below detail the full Diamond Lake & Rocky Mountain Track. For those interested in completing just the hike up to Diamond Lake or the Lake Wanaka viewpoint, view the end of this article for detailed statistics.

Diamond Lake & Rocky Mountain Track
Step-By-Step Trail Guide
Trailhead
The trailhead is located in the Diamond Lake Conservation Area. To get here from Wanaka, drive Wanaka Mount Aspiring Road to the Diamond Lake Conservation Area (about 20 km, 20 minutes). On this drive, you will pass the Roys Peak Track parking lot and Glendhu Bay.
The trailhead is located at the far end of the Diamond Lake Conservation Area parking lot.

Hiking to Diamond Lake
The trail begins from the edge of the parking lot located at the base of Rocky Mountain. Youโll start off on a moderate climb along a wide gravel road. This is arguably the only boring part of the hike. As the road doubles back onto itself, the grade will even out.
Not even 10 minutes into the hike, you will reach a trail split that loops around Diamond Lake. There isnโt much of a difference between the directions you take as both will follow along Diamond Lake. For those looking to reach the Rocky Mountain summit quickly, take the left path, which is slightly shorter.
For those who want to enjoy a stroll around Diamond Lake, continue right. The trails will converge within a third of a mile.
Diamond Lake Bird View
Shortly after passing Diamond Lake, youโll begin a steep ascent through the trees. Expect a rocky track with a few staircases thrown in. Youโll knock out a good portion of the hikeโs elevation gain here, so continue pushing forward.
Ten minutes after beginning this ascent, youโll reach the Diamond Lake Bird View. Here you can enjoy a view overlooking the lake below as well as a prominent mountain pass further on. This will be your last view of Diamond Lake until your descent, but donโt worry. The sights only get better from here on up.
Diamond Lake Bird View
Lake Wanaka Viewpoint
A few short minutes later, youโll reach another trail split. Take the left trail if youโd like to head straight up to Rocky Mountain summit. If you want views over Lake Wanaka, travel the trail on the right. We recommend taking the right trail as the views you receive are incredible and not offered on the left trail up to Rocky Mountain.
Upon taking the right trail, youโll be treated to your first views of Lake Wanaka about a mile into the hike. The trail will slowly ascend along a dirt path. Follow this in the direction of Lake Wanaka. At 2 km/1.25 miles, a spur trail will appear to the right. Follow this for another quarter mile to reach the Lake Wanaka viewpoint.
The view speaks for itself. This panoramic lookout is incredible and definitely worth the extra effort. Feel free to spend some time here to refuel and soak in the landscape.
Lake Wanaka Viewpoint
Rocky Mountain Summit
Once back on the main trail, continue upwards towards Rocky Mountain. Youโve already knocked out more than half of the routeโs total ascent, but from here to the summit, expect a steeper trail. Up here youโll find less hikers and also a less-traveled path. The trail now is thinner and overgrown at some points.
Two miles into your hike you will reach the final trail split. Both directions lead to the Rocky Mountain summit and are of relatively equal difficulty. Take the right trail so you can continue to enjoy views out over Lake Wanaka.
The view from the trail
Your climb will continue for another half mile before reaching the summit. Here the trail becomes narrow as you hike along the cliffside and climb in a series of switchbacks. With every step you take, the sights only get more expansive.
Including the spur trail for the Lake Wanaka viewpoint, youโll reach the summit of Rocky Mountain at 4.2 km/2.6 miles. Here youโre treated to wonderful 360 degree views of Lake Wanaka and the surrounding mountain ranges. It takes roughly 2 hours to reach the summit from the carpark given the route thatโs been described above. This is the perfect spot to enjoy a picnic lunch, as the views donโt get much better than this!

Finishing the Hike
On your descent, you have the option to take the trail you ascended on or the western path. The western path is a more direct trail down to the carpark but be prepared for some steep sections with thick overgrowth. This is a thin dirt path that cuts between high grasses and bushes, but for the most part youโll be exposed to the sun similarly to your ascent. You wonโt have any views out over Lake Wanaka, but youโll still be able to admire the mountain ranges. Itโs roughly a 3.7 km/2.3 mile descent in either direction on your trip to the finish.

Our Route Recommendation & Alternatives
When we completed the Diamond Lake & Rocky Mountain track in April of 2023, we chose the routes outlined in the article above. Luckily, there are numerous ways to complete this track which we have outlined below. These routes are all shorter versions of the full trail described earlier in this article. If you complete the full trail, you will pass all of these major viewpoints.
Diamond Lake Only
For those that want an easy hike and still enjoy some pretty scenery, this short but sweet trail is perfect.
From the car park, follow the trail up to Diamond Lake. At the split that takes hikers up to Rocky Mountain, go right to loop around Diamond Lake. Follow this trail back to the carpark.
Distance: 2.1 km (1.3 miles) roundtrip
Total Ascent: 75m (245 feet)
Difficulty: Easy
Time: 40 minutes
The view as you circle around Diamond Lake
Diamond Lake Bird View
This is only slightly longer than the Diamond Lake hike with an extra climb.
Here you can enjoy a walk around Diamond Lake and see it from a birdโs eye view. Add an additional 0.24 km (0.15 miles) if circling around Diamond Lake on the return.
Distance: 2.6 km (1.6 miles) roundtrip
Total Ascent: 147m (483 feet)
Difficulty: Easy to moderate
Time: 1 hour 15 minutes
Rocky Mountain Lake Wanaka Viewpoint
This route is a little over half the distance of the full Diamond Lake & Rocky Mountain track.
Here youโll take a spur trail that leads to some absolutely incredible shots of Lake Wanaka. This route is ideal for those that want to enjoy the panoramic views of Lake Wanaka without completing the full 7.3 km (4.5 miles) hike.
Distance: 4.5km (2.8 miles) roundtrip
Total Ascent: 260m (852 feet)
Difficulty: Moderate
Time: 2 hours
Our Recommendation – Full Route:
For those interested in completing the full route, we recommend taking the paths described in the article above up until reaching the Rocky Mountain summit.
Take the short path on the left side of Diamond Lake, hike up to the Diamond Lake Bird View, and continue onto the spur trail to visit the Lake Wanaka Viewpoint. From here, hike back onto the main trail, continue your climb until reaching the final junction, and take the right path to the Rocky Peak Summit. Upon summiting, take the same trail back down. This allows you to enjoy looking out at Lake Wanaka on both your ascent and descent. When back at Diamond Lake, take the trail that splits left to enjoy a longer stroll around the lake.
Between the Lake Wanaka viewpoint and the Rocky Mountain summit, the views over Lake Wanaka do get better, but not by a crazy amount. For those that are either short on time or donโt want to complete the full route, we recommend the Rocky Mountain Lake Wanaka Viewpoint trail.

What to Bring on the Hike

Hiking poles. Hiking poles are optional but they take the stress off of your legs and help to ease leg pain and fatigue.
Water and snacks. At least 1 liters of water in the summer.
Sunscreen, hat, and sunglasses. For much of the hike you will be exposed to the sun.
