A couple of 🍁 Novembers ago, MBFF set off on a short hike that I’d been wanting to do for a while: Le Sentier des Arpelières in Crest-Voland (or Les Saisies), Val d’Arly.
I have hiked all over the world, but – hand on heart – 🍁 the autumn colours and 🍄 the magical nature of the terrain on this hike make this 🍂 one of my all time favourite autumn strolls! This hike (really a stroll) is easily accessible for the whole family, and it is annotated in a way to keep little ones engaged from start to finish!
The Val d’Arly website describes the hike as ” un petit air de Scandinavie flotte sur la Réserve Naturelle Régionale de la tourbière des Saisies, un site naturel protégé de 290 hectares, et vieux de 10 000 ans “. Having hiked a little bit in 🇳🇴 Norway and 🇮🇸 Iceland, I can see from where hails this comparison!
The Réserve Naturelle Régionale de la Tourbière des Saisies – Beaufortain – Val d’Arly (292 hectares) is located on le plateau du Lachat, between 🗻 the massif du Beaufortain and 🏞 the vallée de l’Arly, between 1550m and 1718m altitude (in the Forêt Communale de Crest-Voland), and it is a relic of the last ice age! The Sentier des Arpelières was built in the heart of this reserve, and it allows you to discover the fragile biodiversity of 🌱 the tourbières (peat bog wetland), by using the wooden walkways.
You’ll walk through : 🌿 high altitude sphagnum moss; 🌱 moorland; 🌳 forest;
. . . and you may spot : dragonflies; 🦉 mountain owls; the tetras-lyre . . . / the extreme conditions of the tourbières (cold, permanently damp) means that only certain species can survive here – in total, there are more than 100 protected or rare species living here!
[ ⇒ more information about tourbières here ]
The trail will remain open until 🗓 22nd October 2022, so you have a month to enjoy it!

The perfect picnic spot
We started our hike with 🍏 a picnic! There is a picnic table by 💦 the Nant Rouge river, right by the start of the trail . . .


There are also 🍏 picnic tables and plenty of benches along the trail – beautiful !



A 📷 photo treasure hunt
I decided to set my boys – big and small – 📷 a photo challenge for the trail! They had to take photos of about 15 items, and they loved this:
🍄 mushroom – ✅;
🍂 peat bog – ✅;
🐜 ant – ✅;
pine-cone – ✅;
The hike step-by-step – in 📷 photos
At the start of the hike, you’ll find a couple of panels with some information about the tourbière and the Sentier des Arpelières and 🗺 a map of the possible boucles . . .




You’ll spend much of the time on wooden walkways and wooden stepping stones (it can be very wet underfoot!) – kids love this!


The hike starts in 🌲 the forest . . .






Along the trail, you’ll find 🗺 maps and arrows reminding you where you are . . .
And then, still in the forest, you’ll be rewarded with 🍂 an explosion of colour . . . the myrtilliers in October are so photogenic!


On our 2021 visit (very wet underfoot!), there were still some myrtilles to pick and eat – as you can see, my little one really made the most of this!
Be sure to stop to read the instructive 🗺 explanatory panels along the trail – you’ll learn lots about the tourbière and the endemic flora and fauna! And the panels have some fun games for kids . . .



At a certain point, the forest begins to opens up, and 🍂 in autumn, the colours are just amazing on the tourbière surrounding you . . .












Soon after, you’ll come across a cabane d’observation – be sure to leave it as you find it!



After this, the path divides – you can head off to the orange liaison path and smaller yellow boucle, or you can finish the boucle that you are on . . .
If you carry on walking along the red boucle back to Covenan, then you’ll head back into 🌳 the forest . . .



Be warned that the nature of 🌿 a tourbière is that is is extremely 💦 WET – for this reason, AND to protect the flora and fauna, you are asked to stay on the wooden passerelles, where applicable . . . small children (or bigger ones too!) may end up with a wet foot or two (certainly muddy feet!), so it would be a good idea to keep a spare pair of socks (and shoes) in the car for your return!
