Winding through the springtime lanes of Carmarthenshire—past ancient oaks, over quaint stone arches, and alongside a patchwork of lush woods, boggy moors and flower-speckled pastures—I couldn’t help but recall the childhood maps I used to construct: whimsical sketches of fantasy islands with distinct, labeled zones—names like “Misty Hills” or “Barren Bog.” While those imagined wilds remain enchanting, I had a very real kind of hidden treasure in mind on this journey.

Beyond its postcard-worthy farmland, medieval ruins, beachy villages, and vibrant towns (including Dylan Thomas’s beloved Laugharne), Carmarthenshire bears another distinction: the Garden of Wales. That revelation surprised me, despite having family roots here. Over the years, I’d popped into landmarks like the National Botanic Garden and Aberglasney Gardens, their colors and planting styles always impressive.

But as more wonderful places to explore, eat, and stay sprang up in this corner of Wales, I began to imagine a kind of dream itinerary for garden lovers: a mix of top-tier gardens, scenic walks, welcoming pubs, and a cosy inn to call home. This spring, I finally set out to follow that path.

Choosing a base was first on the list. Roughly midway between Carmarthen and Llandeilo sits the peaceful hamlet of Brechfa—a cluster of stone houses, local shop, pub, and chapel tucked beneath forested hills and near the fizzing River Cothi. Anchoring this little gem is Tŷ Mawr, an elegant Grade II-listed hotel and restaurant. With its spacious rooms (Tŷ Mawr translates as “big house”), dog-friendly policies and focus on quality food, it’s perfectly placed for exploring nearby highlights—all within a short 20-minute drive. Our hosts for the stay, David and his partner Gill, took over the hotel in 2022 and greeted us warmly as we arrived after our trek from Hampshire.

Though tempted to linger in the hotel’s apple-scented garden and patio, our first stop was Abergwili’s Bishop’s Park and Gardens. Now cared for by the Tywi Gateway Trust, this once-neglected estate on Carmarthen’s fringe has seen new life thanks to charitable support. Its lovingly restored grounds include a lakeside meadow, curated woodland trails, and historic trees once planted for status—think monkey puzzle and dawn redwood. The heart of the space is the Jenkinson Garden, a series of Victorian-style beds bursting with seasonal vibrancy. Walking the garden, head gardener Blue Barnes-Thomas shared future plans—like revamped greenhouses and a reimagined 18th-century walled garden complete with heirloom gooseberries.

We lunched next at Wright’s in Llanarthney. Co-run by food writer Simon Wright and his wife Maryann, the place delivers artfully simple dishes with refined flavors, including a standout asparagus salad.

Should one indulge in a glass or two of wine over lunch, Aberglasney Gardens lies just across the valley—a visual feast that’s intoxicating in its own right.

Like Bishop’s Park, Aberglasney tells a story of rebirth: once falling into decay, its grand house and lavish 10-acre garden were restored and opened to the public in 1999. Today it dazzles with themed areas—alpine, Elizabethan cloister, kitchen gardens—and vibrant displays like fritillaries and camassias. An indoor ‘ninfarium’ and Penelope Hobhouse-designed walled garden add to the charm. Since 2011, horticulturist Joseph Atkin has guided the garden’s evolution, solidifying it as one of Britain’s gardening gems.

Atkin later shifted focus from gardening to gastronomy, opening The Plough pub nearby in Felingwm. It’s a laid-back spot for wood-fired dishes, local beers, and, if you ask nicely, a bite of plant talk on the side.

A drive deeper into the brightening afternoon led us to Llandysul, to one of Wales’s standout plant nurseries. Farmyard Nurseries spans over a hectare of tunnels, stock beds, and displays, known for its robust and diverse offerings—especially show-stopping hellebores.

Its secret delight lies out back: a woodland garden where Japanese maples brush shoulders with bold rhododendrons, and woodland perennials like yellow comfrey thrive under tree canopy. Nursery owner Richard Bramley shared stories of this playful, unexpected space—ponds, a fantasy-like hut, and more—imagined as they built. We left with some wonderful finds: a pot of anise-scented agastache ‘Blackadder’ and a vivid red aquilegia I'd long sought after.

If you’re still chasing garden magic, Norwood Gardens—on the way back to Brechfa—offers a relaxing last stop with plantings inspired by Mediterranean, woodland and wetland scenes. But we were eager to return for Tŷ Mawr’s three-course dinner, which featured a rich butter bean cassoulet and succulent braised hake.

Our dinner plans nearly derailed, quite literally, when the car gave out high above Tŷ Mawr on the moors between Llandysul and Brechfa. It was actually amusing how remote the road was—an alternator failure in perhaps the most dramatic location. Thankfully, a helpful local mechanic had us back on track within the hour—just in time to dip into some earthy mushroom pate.

The next morning offered a slower rhythm, ideal for one of Brechfa’s numerous forest trails overseen by Natural Resources Wales. We wandered the Keeper’s Riverside Trail, its path lined with delicate cuckoo flowers and lit by misty shafts of sun. While the area is popular with mountain bikers and riders, some trails, including the experimental Brechfa Forest Garden, await repairs post-storm. This hidden conifer collection from the 1950s promises a unique visit once reopened.

Heading south and crossing the River Tywi again brings you to the National Botanic Garden of Wales. Rather than beelining to the famed Great Glasshouse—the largest single-span in the world—we took our time. A path winds past dreamy lakes lined in daylilies, rich borders, and themed gardens—Japanese, walled, kitchen, tropical. Finally reaching the glass dome, we wandered through plant zones representing far-flung ecosystems—from tough Australian shrubs to exotic South African blooms and towering Macaronesian flowers.

The garden’s mission expands beyond beauty: it’s invested in restoring Wales’s native flora and bringing nature into every schoolchild’s education.

This mission will be made even more accessible by a new cycling route opening soon. Following a disused railway line along the scenic Tywi Valley, the path will connect Bishop’s Park with the botanic garden, Aberglasney, and Wright’s café—making car-free trips possible.

This exploration was made possible thanks to Discover Carmarthenshire and Tŷ Mawr Hotel and Restaurant (double rooms starting at £140 including breakfast). Lunch was kindly hosted by Wright’s.
