Hawaii boasts plenty of indoor/outdoor markets that are dog-friendly, which gives you an excuse to walk them and something to do at the same time. Plus, if you find new dog toys, treats, or food, you'll have the perfect tester right by your side!
Hawaii has loads of dog-friendly places to eat and drink, complete with outdoor patios with at least some semblance of shade or rain cover. Even if you don't want to fully get outside, at least you can get some good eats instead!
While rainy days in Hawaii are significantly warmer and nicer than most other places, getting stuck with them can still sometimes be a drag, especially if they infringe on any pre-made plans. But hopefully with this guide, you can find some fun and interesting alternate ways to enjoy being outside anyway. After all, while you may not have the sun, you can still have some fun!
