Al-Sahaba Mosque in Sharm el-Sheikh is a relatively new and architecturally stunning mosque, considered a major landmark in the city. It's generally accessible to tourists of all faiths outside of prayer times, but modest dress is required (women will likely need to cover their heads and shoulders). Visiting independently is common and easy, though guided tours of Sharm el-Sheikh often include a stop here. There aren't significant seasonal restrictions, but the heat can be intense during the summer months, making early morning or late afternoon visits more comfortable. Entrance is free, but donations are welcome. A typical visit lasts about 30-60 minutes, allowing time to admire the architecture and interior. Remember to be respectful of worshippers and maintain a quiet demeanor while inside.
