Start your day with an early drive out of Ljubljana, picking up coffee and a kremna rezina from a bakery in the old town before heading east on the A2/A1 toward Novo Mesto. Pause for a short stroll along the Krka River at Otočec to admire the fairytale castle and river views, and then continue through rolling countryside, stopping at a roadside vinoteka to sample a glass of Dolenjska cviček as you stretch your legs.
Carry on toward the Prekmurje region with a leisurely lunch in Murska Sobota — try local prleška gibanica or bograč at a cozy inn — then detour to the thermal spa village of Moravske Toplice for a walk through its park and a quick soak in a thermal pool if time allows. Afterward, drive the scenic smaller roads to Lendava, enjoying patchwork fields and occasional vineyards as the light softens across the plain.
Arrive in Lendava in time to explore the town center and climb the Lendava Castle for panoramic sunset views over three countries; visit the modern Vinarium observation tower nearby if you prefer a higher vantage point. Finish with a relaxed dinner at a local guesthouse sampling Prekmurje specialties such as bujta repa and a glass of regional wine, then wander the quiet streets or settle in for a peaceful night in town.
