Whether you’re travelling with kids, dogs, or both (we see you, brave multitaskers!), there are plenty of indoor and sheltered spots that’ll keep everyone smiling.

We’ve rounded up the best dog-friendly and family-friendly rainy day activities, all within easy reach of Anglesey, perfect for keeping tails wagging and kids entertained.

Built to impress, even in the drizzle! Beaumaris Castle has towers and walkways to explore, with some shelter from the elements. Dogs on leads are welcome, and it’s a real hit with kids who love a castle adventure. Plenty of dog-friendly eateries in this pretty town – worth a visit, whatever the weather!

While in Beaumaris, why not visit Beaumaris Gaol, a fascinating insight in to 1800s prisoners. While it’s not dog-friendly, they allow dogs into the reception area, so one can volunteer to stay with the dogs while the rest of the family discover the grizzly past! Read our blog for further details of our visit, where Neil volunteered to babysit the dogs and even got a coffee from the friendly staff! 

🌾 Melin Llynon – Anglesey’s Last Working Windmill

A charming stop whatever the weather! Explore the mill, grab a drink and the famous monuts in the takeaway and gift shop, or visit the Iron Age roundhouses. Much of it is outdoors, but there are covered areas too – and dogs on leads are welcome.

🚤 Moelfre RNLI Lifeboat Station – Rescue Heroes in Action

This small but mighty lifeboat station offers insight into local sea rescues and coastal safety. There’s a viewing gallery, display boards, a shop and the chance to meet volunteers. Kids will love it, and pups are welcome too!

Parking by the lifeboat station is next to impossible so recommend to park at the RNLI Pay & Display car park (LL72 8LG) and walk from there.

🏛️ Plas Newydd House & Gardens, Llanfairpwll

Ideal for families who don’t mind splitting up – one adult can explore this National Trust elegant mansion, while the other enjoys a woodland walk with the pup, with plenty of coverage amonst the trees. And besides, the views are lovely, even on a grey day!

Sheltered Outdoor Walks

🌲 Newborough Forest – A Walk in the Rain, Without the Mud!

When it’s drizzling but you still want to stretch your legs, Newborough Forest is the perfect escape. Thanks to its sandy soil and dense canopy of towering pines, the trails here stay surprisingly dry – even after a downpour. The trees offer great shelter from wind and rain, making it a favourite for dog walkers and families looking for a peaceful outdoor stroll without the soggy socks. 

There are plenty of free and Pay & Display car parks to use, but be aware that they get full during holidays and peak season. We prefer one of the southern car parks near Pen-Lon (LL61 6RS) and then a short walk along the dunes to the forest and beach.

🌳 Nant y Pandy (The Dingle) – Llangefni’s Hidden Woodland Gem

Tucked right behind the Oriel Môn Gallery, Nant y Pandy Nature Reserve (locally known as The Dingle) is a peaceful, dog-friendly woodland walk that’s ideal for a drizzly afternoon. It’s well-maintained boardwalks and gravel paths make it an easy and clean stroll, even after rainfall. With a canopy of trees overhead, bubbling streams below, and occasional red squirrel sightings, it’s a hit with families and four-legged companions alike. There are even covered seating spots for a quick picnic under the trees.
