Le Laisonnay: access, waterfall and walking starts

Le Laisonnay is a useful destination in its own right, as well as a trailhead. A visit can stop at the hamlets and waterfall, while hikers continue into separate mountain valleys. Decide which day you want before travelling up from Champagny.

Getting to the start

Official Plaisance approach information names the parking at Le Laisonnay-d’en-Bas. From the main village, the road first climbs to Champagny-le-Haut and then continues up the valley in suitable seasonal conditions. Use the signed parking and keep access clear for residents and working vehicles.

In winter, the road endpoint is at Le Bois according to the park’s Refuge du Bois information. Reaching that point does not establish safe walking access farther up the valley. Confirm current arrangements for your visit, especially outside the summer season.

Choose your outing before leaving the parking

Plan	The key distinction
Hamlet and waterfall visit	Stay with the valley viewing area; you need not climb to a refuge
Glière approach	About 450 m of uphill walking; the dry former lake is farther on
Plaisance approach	About 600 m ascent, with a sustained climb by the Cascade du Py
High-pass outing	A larger mountain itinerary, requiring its own map, conditions and return plan

Use Cascade du Py for a short viewing visit. Compare Glière and Plaisance before choosing a hike; walking times on a sign generally need a separate allowance for the return.

Meals and overnight stops

The Refuge du Laisonnay is a road- or trail-access establishment in the hamlet area. It is different from the higher mountain huts. Check its own opening calendar and reserve if you are counting on a meal or bed; a dining stop should not be the only food provision for a mountain day.

For an overnight farther up, book the named hut and confirm the facilities available during your stay. Guarded summer service and an unguarded shelter are different arrangements. At Glière, the operator’s current closure notice makes direct confirmation particularly important.

Plan the return

If somebody drops you at Le Laisonnay, agree where and when to meet. Confirm seasonal transport stops directly and download your walking map before leaving. Allow enough daylight for the descent and leave time to enjoy the valley without rushing at the end of the day.
