Leave Mount Gambier around 8:00–8:30 AM and take the Princes Highway straight into Warrnambool — it’s usually about 2.5–3 hours with a quick comfort stop, and the drive is an easy one for kids to settle into if you’ve packed snacks and a playlist. Aim to arrive with enough time to fuel up, grab lunch, and park near the foreshore; Warrnambool is very manageable by car, and once you’re near the beach side you can largely leave the car parked and wander on foot. Start with Lake Pertobe Adventure Playground, right by the foreshore, where the teens can spread out between the giant slides, swings, and lakeside paths while you all shake off the drive. It’s free, very casual, and usually a solid 1.5-hour stop without anyone feeling “toured out.”
From Lake Pertobe, it’s a short walk or quick drive to Flagstaff Hill Maritime Village, and this is the one to do before the afternoon wind really starts doing its thing. The museum village and harbour views make a good contrast to the playground, and it works well for an active family because there’s enough to look at without being overly formal; allow about 1.5–2 hours, with entry typically around the mid-range family-ticket mark rather than expensive. If you want a nice, easy transition, grab a casual lunch nearby first or after — the Warrnambool foreshore is the easiest base for the day, and parking is usually simplest around the main beach/foreshore area rather than trying to keep moving spot to spot. After that, head into Warrnambool Botanic Gardens for a quieter late-afternoon reset: big trees, open lawns, and a nice loop for a gentle family wander before dinner. It’s free, and 45–60 minutes is plenty unless the kids discover a game of tag among the paths and terraces.
Finish with dinner at Simon’s Waterfront on the foreshore, which is a good fit for a first-night-in-town meal because everyone can eat properly without it feeling too dressed up. Expect mains roughly in the $25–$40 pp range, and book ahead if it’s a busy evening or school holiday period. Sitting by the water after a big driving day gives the trip a proper “we’ve arrived” feeling, and if the sky is clear, a short post-dinner stroll back along the foreshore is a lovely way to close the day.
Arrive in Apollo Bay with the best kind of family road-trip energy: a bit windswept, a bit excited, and ready for views. Start at Marriners Lookout first while the light is still soft — it’s a short drive up the hill and the payoff is huge, with the whole curve of the bay, the foreshore, and the hills behind town spread out below. Give yourselves 30–45 minutes here, and if it’s a crisp clear morning, the coastline looks especially dramatic. From there, roll back down into town for a barefoot reset at Apollo Bay Beach; this is the easy, no-pressure stop where the teenagers can wander, kick a ball, or just warm up in the sand for 45 minutes or so.
Before the day gets too settled, head inland into Great Otway National Park for a family-friendly forest walk — in this area, the short tracks around Melba Gully or similar easy-access sections are ideal for giant tree ferns, cool damp air, and that proper rainforest feel without turning it into a full hike. Plan 1.5–2 hours so you’re not rushed, and wear shoes that can handle muddy patches. Then continue to Maits Rest Rainforest Walk, which is one of the best low-effort, high-reward walks near Apollo Bay: the boardwalk loop is usually around 30–45 minutes, and it’s perfect for all ages because it feels immersive without being strenuous. For lunch, swing back to Apollo Bay Fishermen’s Co-op on the harbour side for a simple seafood feed — think fish and chips, prawns, scallops, or a grilled catch, usually around $20–$35 per person depending on what everyone orders.
After lunch, keep the afternoon loose rather than overloading it — that’s the secret to a good Great Ocean Road day. Wander the foreshore, grab a coffee or ice cream in town if needed, and let the kids have a slow hour to themselves before the last stop. In the late afternoon, finish at Apollo Bay Harbour for a gentle walk as the light drops; it’s a lovely place to spot fishing boats coming and going, seabirds along the waterline, and occasionally a seal if you’re lucky. It’s an easy 30–45 minute finish, and a nice way to end a nature-heavy day without needing to “do” anything.
Leave Apollo Bay after breakfast and aim to roll into Lorne with enough time to ease into the day rather than rush it — the drive along the Great Ocean Road is short enough that you can be selective, stop for photos if the light is good, and still make a proper morning of it. Start at Teddy’s Lookout, which is the classic “wow” first stop here: the estuary, the curve of Louttit Bay, and the ocean all line up beautifully from the viewing platform, and it only takes 30–45 minutes. Parking is free but limited, so an earlier arrival is nicer. From there, head down to Lorne Beach for a barefoot wander along the foreshore, a look in the rock pools if the tide is low, and a bit of unstructured family time. It’s the kind of beach where teenagers can split off a little, so long as you keep one eye on the water and the conditions.
Once you’re warmed up, drive inland to Erskine Falls in Great Otway National Park — it’s one of the most dependable waterfall stops on the coast, with a lush ferny feel that makes the whole place seem cooler even in winter. Allow 1–1.5 hours, because it’s worth taking your time on the steps and at the lookout, and the forest drive itself is part of the fun. After that, shift gears for your surprise pick: Live Wire Park. This is the day’s teenage win, with treetop challenge elements and ziplines in a forest setting, and it usually runs best as a 2–3 hour block. Book ahead, especially in school holidays and weekends, and expect it to feel energetic rather than leisurely — ideal for a 13- and 16-year-old who want something more active than another scenic stop. If you need a calmer alternative for one family member, the setting is still pleasant enough to wait and watch from the ground.
Refuel at Swing Bridge Cafe, right near the river mouth, for easy café food in the usual family range of about $20–$35 per person. It’s a practical spot rather than a destination restaurant, which is exactly what you want before the afternoon energy dips; think toasted sandwiches, burgers, fish and chips, cakes, and coffee. After lunch, keep things soft with a final walk to Lorne Pier. It’s a simple finish, but a good one — sea breeze, boats coming and going, and a last chance to stretch your legs without committing to another big outing. If you’ve still got energy, the foreshore has plenty of room for an ice cream or a slow stroll before dinner back in town.
Arrive in Halls Gap with the biggest drive of the trip behind you, so keep the first half of the day gentle and useful rather than rushing straight into a big hike. Start at Brambuk The National Park & Cultural Centre for a really good reset: it gives the kids context for the Grampians landscape, wildlife, and Gariwerd culture before you head into the hills. It’s an easy first stop for all ages, usually best in the morning, and you’ll want around 1–1.5 hours here. The centre is right near town, parking is straightforward, and there’s no need to over-plan — just let everyone pick up the map, look at the displays, and get a feel for what the day’s walk is about.
From there, it’s a short hop to Venus Baths Loop, one of the best family walks in Halls Gap because it feels adventurous without being overwhelming. The track is generally around 1.5–2 hours with creek crossings, rock shelves, and little pools that make the teenagers feel like they’ve earned something, especially if the water’s flowing. Wear proper shoes with grip — the rocks can be slick even in cooler weather — and take your time on the flatter sections so nobody burns out before the big hike. After that, keep the momentum going with The Pinnacle from the Halls Gap side, which is the marquee climb of the day. Depending on the route and pace, allow 2.5–4 hours return, and go prepared with water, layers, and a snack stop at the top because the views are worth lingering over. It’s one of those classic Victorian lookouts where the whole family gets that “wow” moment, especially if the weather is clear.
Once you’re back down, switch gears completely at Halls Gap Zoo for a lower-effort, high-reward finish to the day. It’s a lovely balance after the hike, and kids usually love that it mixes native animals with a few unexpected exotics — plan about 1.5–2 hours and check opening times before you go, since seasonal hours can vary. By evening, head to Spirit of Punjab for dinner; it’s a solid, family-friendly choice in town with mains around $22–$38 per person, and after a mountain day nobody will mind a relaxed sit-down meal. If you’ve still got a little energy after dinner, take a final slow lap through Halls Gap before turning in — the sunset light in the valley can be beautiful, and tomorrow’s return drive to Mount Gambier is worth planning for an easy departure after breakfast.
Start early and head out for Boronia Peak Walk while the air is cool and the kids still have some energy. This is the “proper hike” of the day — steeper and more committing than a quick lookout stroll, but that’s exactly why it’s a good family adventure for active teens. Expect around 3–4 hours return depending on pace, with a few rocky sections and big rewards at the top; good boots, water, snacks, and a layer are worth it in winter, especially in Halls Gap where conditions can change fast. If you want a quieter trailhead start, be on the track shortly after sunrise so you’re walking before the day-trippers begin drifting around the village.
After the climb, give everyone a reset at Lake Bellfield. It’s the kind of stop that feels simple but works beautifully after a hike: open water, ridgeline views, birdlife, and space to breathe without needing to “do” much at all. Park near the dam and wander for photos, a snack break, or just a sit-down while the legs recover; plan on 45–60 minutes. If you’re hungry, it’s easy to loop back into Halls Gap for an early lunch — grab takeaway or something casual from the village and keep the pace unhurried, because the afternoon has more scenery than intensity.
Drive south to Mackenzie Falls for the day’s biggest wow-factor. It’s one of those Grampians sights that feels genuinely worth the detour, even after a hike earlier in the day: a dramatic cascade, cool air at the base, and a real sense of scale that teens usually get into. The return walk is the main effort here, so take it at a steady pace and factor in time for photos and the lookout sections; allow about 1.5–2 hours. On the way back toward Halls Gap, make Silverband Falls your final stop — short, easy, and perfect when everyone’s cooked but still wants one last nature hit. It’s a nice low-effort finish, especially if you’re traveling with one teenager who’s “done” and one who still wants to explore.
Settle in for dinner at Kookaburra Hotel in Halls Gap — practical, relaxed, and exactly right for a mountain day when nobody wants to overthink it. Mains are usually in the $20–$40 range, portions are family-friendly, and it’s the sort of place where hiking boots and fleece are completely normal. Go a little earlier if you can, because the dining room can fill quickly with other road-trippers, and after a day of climbs, waterfalls, and fresh air, an easy pub dinner is the perfect final-night move before the drive back to Mount Gambier tomorrow.
Roll out of Halls Gap after breakfast around 8:00–8:30 AM and take the straightforward run back to Mount Gambier via the Western Highway and Dukes Highway. It’s the kind of return drive that rewards an early start: you’ll beat the worst of the afternoon fatigue, and the teens will probably appreciate a proper coffee-and-snack stop about halfway. I’d plan one solid break in a highway town such as Horsham, Kaniva, or Keith depending on how the timing feels; fuel is easy to find, and a simple bakery lunch works better than trying to overthink it. Expect the drive to take around 4.5–5.5 hours total, plus whatever you spend stretching your legs, and try to arrive in Mount Gambier with enough daylight left to enjoy the end of the trip rather than just unload bags.
If everyone is hungry and keen for something low-effort, head straight to Pasta GF in Mount Gambier for a simple sit-down meal back in town — it’s the kind of place that suits a tired family well, with mains usually around $20–$35 per person. After days of road food and holiday spontaneity, a familiar pasta dinner is a good reset, and it keeps the last afternoon relaxed. If you’d rather move first and eat after, save it for dinner and use the daylight for one final outing.
If the family still has energy, finish with a gentle wander at Blue Lake Reserve. Late afternoon is the best time to go because the light settles beautifully over the crater lake, and a 45-minute walk is enough to make it feel like a proper last stop without turning the day into another big outing. Park near the main reserve access and keep it easy: this is more about soaking up the view, a few family photos, and that satisfying “we’re home” feeling than about ticking off distance. It’s a lovely way to close the holiday — one last iconic Mount Gambier moment before everyone properly lands back into normal life.
