The interior of Kep peninsula is occupied by Kep National Park, where an 8km circuit, navigable by foot and mountain bike, winds through thick forest passing by wats and viewpoints. Quirky yellow signs point the way and show trailheads to off-shooting walking paths that lead into the park's interior. The 'Stairway to Heaven' trail is particularly worthwhile, leading up the hill to a pagoda, a nunnery and the Sunset Rock viewpoint.
