There's a hike in HK at the Tai Lam Chung Reservoir called the Thousand Islands Hike. I went with one of my friends on the hike after getting lunch together. The hike was easier than I was expecting, with both the beginning and the end being entirely paved, and it wasn't particularly steep, either. I would compare it both Makapu'u Lighthouse Trail and Diamondhead, as some parts were a dirt path, but they also were not particularly challenging compared to some other hikes on Oahu. At the start of the trail we actually also saw goats, which was quite interesting. It was more crowded than some other hikes I've been on here, but given that it's an easier one and we went on a Sunday, it still wasn't particularly crowded. As we continued going higher up tp the top viewing point, the view of the islands only continued to improve. It's a bit further away to access, but it's definitely a hike I'd recommend, even for people who aren't as into hiking.
