Setting out on our first overnight hike deep in the heart of the Blue Mountains was an experience we’ll never forget.
We chose the Pierces Pass to Blue Gum Forest trail, a route known for its stunning waterholes along the Grose River and sweeping views of the towering cliffs surrounding Grose Valley.
From navigating steep descents to camping under a canopy of stars at the Acacia Flat Campground, every moment brought new surprises.
We felt both nervous and exhilarated as we packed our gear and headed out, and everything we discovered along the way made the hike incredibly rewarding.
With sweeping views, lush forests with massive gum trees, and the challenge of carrying everything we’d need, this adventure was a crash course in wilderness trekking, and we’re thrilled to share our tips, highlights, and key lessons.
How To Get To Pierces Pass Trailhead
The quickest way to reach Pierces Pass Picnic Area (staring point of the trail) from Sydney is by taking the B59 route through Richmond:
- Head toward Richmond: Drive northwest from Sydney, following Richmond Road.
- Continue on B59: After Richmond, continue on the B59 (Bells Line of Road) as it winds through Kurrajong and Mount Tomah. This road provides a more direct approach to the Blue Mountains’ northern side.
- Turn onto Pierces Pass Road: After passing through Mount Tomah, keep an eye out for Pierces Pass Road on your left. Follow it until you reach the Pierces Pass Picnic Area.
Pierces Pass Road is an unsealed fire trail that’s generally manageable for 2WD vehicles. However, the last section is somewhat rough, so proceed with care, especially after rain.
The picnic area has limited parking, so arriving early is recommended, especially on weekends. It is a great base to prepare before you descend into the Grose Valley toward the Blue Gum Forest.

Pierces Pass Descent
The journey begins with a steep descent from Pierces Pass, where the trail cuts through dense bush and rocky outcrops.
While the path is well-marked, the steepness adds a level of difficulty that can make for a slower pace. Hiking poles can be a great help here.
After you pass through Pierces Creek, the trail opens up, and you’ll soon be walking through sweeping fields of lush green ferns.
As you continue, Rigby Hill emerges to your left, while the dramatic Blackheath Walls stand tall across the Grose Valley, creating a truly breathtaking backdrop.
The last section of the descent into the Grose Valley is the steepest, but it shouldn’t be too challenging, and soon enough, you’ll see the sign pointing toward the Grose River crossing.
Keep in mind, there’s no bridge here, so you’ll need to do a bit of boulder hopping to cross the river.
Alternatively, you can try what we did—walk a bit further south along the riverbank until you find a spot without boulders where you can just take off your shoes and cross the water easily.
Walking Along the Grose River
After crossing, you’ll find a well-marked and relatively straightforward trail that follows the right bank of the Grose River.
Along the way, you’ll find plenty of scenic waterholes, perfect for a refreshing dip to cool off.
While easy to navigate, parts of the trail are slightly overgrown, so packing long pants and sleeves is a smart choice to protect against the brush.
Reaching Blue Gum Forest
A highlight of the hike, the iconic Blue Gum Forest is filled with towering blue gums that reach over 60 meters in height.
Early environmentalists saved this area from logging in the 1930s, and I’m really grateful for its preservation, as it’s the most breathtaking part of the hike.
Starting with Little Blue Gum, you’ll eventually reach the main Blue Gum Forest, where the largest trees are impossible to wrap your arms around.
Acacia Flat Campground
Located within the heart of the Blue Gum Forest, Acacia Flat is a free, spacious campground that’s perfect for an overnight stay.
With 2 composting toilets, shade, and ample room, it offers a quiet, natural camping experience.
The Grose River is only a 5-minute walk away, ideal for cooling off after a hike. Weekends can be busy here, but it’s easy to find a secluded spot for some privacy.
Spending a night here, under the stars and surrounded by forest sounds, was unforgettable.
Final Thoughts
Taking on our first overnight hike from Pierces Pass to Blue Gum Forest was both challenging and rewarding.
This trail delivers an authentic wilderness experience, testing your strength while immersing you in some of the most beautiful scenery the Blue Mountains has to offer.
Let’s keep this place pristine by packing out waste and leaving no trace, so it stays wild for future generations.
