A summit shelter was built with some of the stones from Wilkes' camp site and mortar in 1934. In 1916 Mokuʻāweoweo was included in Hawaii Volcanoes National Park, and a new trail was built directly from park headquarters at Kīlauea, an even more direct route than the one taken by Wilkes. This trail, arriving at the summit from the east via Red Hill, became the preferred route due to its easier access and gentler slope. The historic ʻAinapō Trail fell into disuse, and was reopened in the 1990s. A third modern route to the summit is from the Saddle Road up to the Mauna Loa Observatory which is at elevation a few miles north of Mokuʻāweoweo and the North Pit trail.
