Debre Bizen is an Eritrean Orthodox monastery perched atop Mount Bizen, near Nefasit. The monastery, founded in the 14th century by Abba Filipos, offers stunning panoramic views but requires a steep climb, making it inaccessible to those with mobility issues. Visits are generally possible year-round, but the climb can be challenging during the hotter months. Given the rugged terrain, a guided visit is highly recommended, especially for first-timers, and women are not permitted to enter. Expect the visit, including the ascent and descent, to take a full day. Costs primarily involve transportation to Nefasit and hiring a local guide, which may vary but is generally affordable. As a religious site, respectful attire is essential.
