Not really. I've made a little path from the ramp to the dock with trees but that's pretty much it. I mainly use it for flower storage and flower breeding.
Right now I'm using it to breed flowers and such so that they won't get trampled by villagers, but later on I want to decorate it with paths and such, as well as with specific flowers.
I've planted coconut and banana trees, but that's it. I'm growing hybrids there at the moment, but when that's done, it'll go back to being flower-free because I think that looks more natural. It'd be nice if we could put PWPs there though... I'd put a hammock and a picnic blanket there if it was possible
I haven't really decorated my own beach (aside from the palm trees and such) but i did gather all the sea shells on my friend's beach every day for a few days into a corner of her beach (you know, purely as a modern art exhibit!) until she noticed. Good news! She thought it was hilarious.
i use a small portion of my beach to grow hybrids. for the rest, im planning on planting banana and coconut trees, lay out a neat pattern of hybrids and look for some qr codes
All three (soon to be four) of my beaches have alternating coconut and banana trees.
In Ruddyoak, I also have alternating blue and orange pansies against the cliff edge, and I leave the shells as they wash up naturally. No paths on that beach, though I may add some later. The private beach is home to my blue roses, because I like having them but they don't fit with the rest of the town.
In Goblin, I added paths I made that matched the feel of the town, plus gyroids to represent the goblin population of the Goblin City. The private beach has "secret stuff" on it that also fit the theme of the town.
(I visited my mom's town once, and noticed she'd spelled out "HELP" on her beach using flowers. I pointed out that she could have spelled "SOS," but I like it the way it is.)
Not sure if you'd all what I do with my beach decorating I basically have an absolute ton of hybrids how thanks to some giveaways, and I love my flowers so I can't sell them or anything (although I have given some away the other week). I put them all on my two beaches, I try to keep them in sections according to their colour. At the minute I have a massive section of blue roses, then Jacobs ladders, then blue pansies and then purple roses. It looks really pretty but it's such a pain when I'm in a hurry with fishing or something and I can't run
