Opening Dates & Times We are now open for the season until 31st October 2019. The gardens, playgrounds, tearoom and lakeside walks are open daily from 10:00am to 5:00pm. The house is open to visitors from 1:30pm to 4:30pm (last entries 4:00pm) on Sunday, Wednesday and Thursday afternonns. The grounds at Mirehouse are certainly dog friendly. Dogs are welcome in the grounds on a short lead at all times. Just be aware, it is an offence to allow your pet to bother any livestock. Please keep your dog on a lead and give farm animals plenty of space not to feel intimidated. Cows on the other hand may be more curious, but should they charge toward you, drop your dog lead and run to safety. Your pet will be able to outrun any danger by itself. Be especially vigilant around livestock.
