HikingaroundtheWorld - Honolulu

Hikers rejoice! Diamond Head State Monument offers breathtaking views overlooking the Pacific Ocean and Honolulu. In fact the view is so good, it was used by the US military as a post for preventing attacks against Honolulu. The trail takes you to the edge of a 300,000 year old crater. While the hike isn’t that long in terms of distance, it can be somewhat challenging due to its ascent. Parts of the trail are over uneven rock, and the 99 steps near the end of the hike are steep. Also, the only water fountains are at the beginning of the trail, so you’ll want to bring a water bottle or bottled water to stay hydrated. https://hawaiistateparks.org/parks/oahu/diamond-head-state-monument/

Waimea Falls, also known as Waihi Falls, is one of the more accessible falls on Oahu. It is located within Waimea Valley, which is a unique Hawaiian botanical garden within a significant cultural and archaeological site. There is a small fee to enter the park. This is a worthwhile contribution, as the place is dedicated to the preservation of the incredible botanical and cultural features of the area. https://www.hawaii-guide.com/oahu/hiking_trails/waimea-falls
