For a one‑week trip beyond Istanbul, suggested destinations include: Konya (resting place of Maulana Rumi, strong spiritual and historical appeal), Cappadocia (unique landscapes, cave hotels, hot‑air balloons), Isparta and Afyon (less touristy, good for experiencing inland Turkey). Coastal resorts are also pleasant and worth visiting, but the recommendations focused on inland areas for culture and history. Your final choice should balance family interests, season, and travel times between cities.
