At the beginning of this year I moved home, and am now fortunate to be back close to where I was when I began this blog over a dozen years ago, a short walk away from the seafront. It’s been lovely to wander and reacquaint myself with the trails of my old patch and to explore some potential new ones, as always on the lookout for opportunistic wildlife and also for changes that have come about since those earlier days, and for better or for worse any effects they may have had.
One of my favourite, and very often most productive trails follows a length of the Coast Path beginning at the harbour in Rhos on Sea, where the back of the beach is a haven for an eclectic collection of ‘pioneer plants’, some coastal wildflowers, a few garden escapes and other opportunists that most people dismissively call ‘weeds’. Following on from there is the stretch of rocky shore and mussel beds of Rhos Point, which from late summer until spring is a draw for good numbers of wading birds, gulls and occasional surprise visitors on their migration passages. This spot always merits a lengthy pause, but continuing on, passing the little chapel of St Trillo, walking up towards the higher level of the promenade and along a short way, you reach what I find to be one of the most fascinating stretches of the trail and it’s where I finally settled on beginning this new chapter of posts.
26 May 2026 – Rhos on Sea Promenade-St Trillo’s Chapel to Penrhyn Bay
Beyond the chapel the promenade changes levels and a sloping retaining wall supports the raised upper level. In front of the wall is a line of commemorative wooden seating benches and behind them, where wind-blown seeds of an interesting array of flowers, both wild and ‘escaped’ may settle and flourish.
At the moment golden-flowered hawksbeard predominates and will hopefully set seed before someone complains they look messy and the council are obliged to clear them.
For now though they are doing an excellent job of provisioning a variety of insects, including two beautiful painted lady butterflies, the first I’ve seen this year. One of them was already looking a little faded and worn around the edges and no wonder after the journey it must just have made.
The butterflies weren’t the only diners, there were bumblebees and hoverflies feasting too.


Still fairly early morning it was warm, the sun yet to completely burn off the mist blurring the horizon and the outlines of the Little Orme headland. The tide was fully in but the blue sea was almost flat calm and barely made a sound as it met the rocks. My only company was a lone Herring gull and even it disappeared as I got closer.
Where the dark railings end and opposite steps going up to Marine Drive, another set of steps lead down to a parallel walkway. On the official signage warning of potential dangers that may be met with here, this is referred to as the ‘lower parapet’ and runs between the old recurved sea wall and the formidable barrier of huge piled rocks. Also known as revetments or rock armour, these monstrous lumps of rock heaped in a continuous barrier between Rhos Point and Penrhyn Bay, are a crucial reinforcement to the existing aging coastal defences battling with rising sea levels and wave batterings during storms, and are between Rhos Point and Penrhyn Bay. I’ve written about this path in the past, and the description of it that always comes to my mind is that it’s ‘between the rocks and a hard place’, which is the reality, but despite that over the last few years it has become a go-to place for me and I never cease to be amazed at the number and variety of species of plants that I have found thriving there and the wildlife that they attract.
It’s interesting that in terms of plants, it is a path of two halves. The first, perhaps because it is wider and feels more open has noticeably less plants and those that have found themselves growing there are more susceptible to prolonged periods of drought, but for now those that are there are flourishing. One of my favourite, and probably the most frequently found plant on the limestone walls and alongside pavements throughout the village and beyond, pellitory-of-the-wall, has managed to establish in a few places. Another favourite is the Seaside daisy, which has escaped from the confines of local gardens and settled quite happily all over the place, There’s sea beet there too, which looks at its best now while its leaves are fresh and glossy and the flower spikes still in bud.


At a junction with steps leading up to the upper promenade to the left and a wide concrete access ramp down to the shore, the path dog-legs slightly and narrows to continue along to Penrhyn Bay. This is where the density of plants and number of species increases and gets altogether more interesting, beginning with two big shrubby tree mallows, both taller than me and full of beautiful blossoms. Bumblebees seem to love the big open pollen-laden flowers of the tree mallow and there were several busily gathering here, including a big beautiful buff-tailed queen.


Beyond the mallow the plants grow closely together, forming an almost-continuous border to the path. Most prolific, and beautifully colourful against the grey rocks is red valerian, predominantly pink in flower, but there are also red and white flowered plants.


The valerian was a beautiful sight, but even better, it had been discovered by a dozen or so more recently arrived painted ladies, all no doubt refuelling after their incredible journey across the sea.
Sea beet grows especially well here and is looking its best now with glossy green leaves and flower spikes still in bud. Later it will change shape and sprawl across the path. Next to it in this photograph is some white flowered red valerian and a clump of goosegrass aka cleavers, or even sticky willy, if you prefer.
One of the most surprising plants here is a big elder, which sprawls out across the rocks. Some of its creamy flowers are already fully open with many more still in bud.
A herring gull flew in and stood atop a rock long enough for me to take its picture. However you feel about them, it’s hard to deny that they are very handsome birds, especially at this time of year when they’re in full breeding plumage.
A smooth sow thistle is both flowering and setting seed. Nearby there are several plants with large distinctive leaves that I didn’t immediately recognise when I first saw them, but that I thought might well be those of prickly lettuce, (which is quite closely related to the sow thistles). I have no idea from where it would have travelled to arrive here as I haven’t come across the plant growing anywhere else locally, but it looks to be quite well established and I’m looking forward to seeing it in flower.

Herb Robert does very well here, this is a particularly large plant which looks especially pretty as some of its leaves have turned red.
A big sprawling bramble is one of the favourite gathering places for one of the local house sparrow colonies and is a great source of pollen and nectar for all kinds of bees when it flowers.
Past the bramble the flowering plants are a little more spread out, but there is one particular treasure of a plant that I’ve so far only found at this end, although it is slowly spreading, and that is that is a pretty sea spurrey; I’m not absolutely certain which species it is (there are three similar ones), but I think it is most likely lesser sea spurrey.


Between this end of this length of path and up to where the shingle beach of Penrhyn Bay begins is a stretch fortified with so much rock, which has been put down and added to numerous times over the years, (and in fact is still being added to), that you could almost imagine yourself on another planet. It looks stark, but there’s plenty of life here too, which I’ll save mentioning for another day.
