These are usually the routes I take, and I’ll go into them in more detail below. One of the unique features of Lac de Louvie is the Cabane de de Louvie which is perched above the lake with the most amazing view. Hikers can take a rest, grab a meal or even spend the night. I really like to spend the night up there and shoot the Milky Way over the Grand and Petit Combin reflected in the lake, or even get up early enough to capture the sunrise and if the wind speed is low enough, capture the still water with the mountain peaks reflected in the lake.

There are few ways to access the lake, but the two I predominantly take are the following:

Route 1: Fionnay > Lac de Louvie loop - 7.8km - Approx 4-4.5hrs

This route is a steep climb and not for the faint hearted especially if you have a fear of heights. But it is impressive scenery and slightly shorter/quicker if you have less time. I find it a tough climb when I have all of my camera equipment on my back, but it’s always worth it.

• Distance: 7.8 km return

• Highest point: 2,250m (Cabane de Louvie)

• Height gain: 777 m↑↓

• Difficulty: Fairly steep climb with some steep drop offs. There are chains to hold on to in one section
  

Route 2: Ruinettes > La Chaux > Lac de Louvie > Fionnay - 14.9km - Approx 5.5-6hrs

• Distance: 14.9 km

• Highest point: 2,648m (Col Termin)

• Height gain: 777 m↑ 1485↓

• Difficulty: Fairly steep climb with some steep drop offs. There are chains to hold on to in one section

You can also loop back on route 2 as well of course. From Fionnay there is a small bus that takes you back round to le Chable and then you can get the lift back up to Verbier if you are staying there.

I would highly recommended starting the hike early in the day, so you can make the most of the daylight and avoid afternoon thunderstorms which can occasionally occur in the Alps during summer.

Remember, no matter when you hike, it's essential to have the right equipment and to stay safe. Even in the summer, the weather can change quickly in the mountains, so be prepared with warm and waterproof clothing, adequate food and water, and a good map or GPS device.

Lastly, always respect the environment and wildlife by staying on the trail, packing all trash, and following any local regulations or guidelines.
