Hotel Diehlberg – Tagungs- & Wellnesshotel  

Perched on a peaceful peninsula by the Biggesee in Olpe, this wellness-focused hotel sits right on hiking and cycling routes. It’s a short drive from Rothaar Mountains Nature Park and Listertalsperre, and is connected to a nearby rail station for easy access.

Freshly renovated from its days as a family retreat, the vibe mixes modern wellness with cozy lounge corners and a fireplace for evening drinks. Rooms are simple and comfy — flat-screen TVs, minibars, bathrobes and slippers, plus bathtubs or showers in many rooms. Expect restful nights with lake air and easy access to outdoor trails.

A full-service spa offers massages, body treatments and facials alongside a sauna and steam bath. Take a dip in indoor and outdoor pools, hit the 24-hour fitness center, or try mini-golf, ping-pong and the arcade. There’s also a playroom for kids, concierge and transfer services, plus on-site parking and laundry/dry-cleaning.

Five meeting rooms and a business center make this a solid pick for events and meetings. Complimentary wireless internet, luggage storage and free self-parking keep work simple and practical.

An on-site restaurant and cozy bar serve up breakfasts and evening drinks by the fireplace. Buffet breakfasts run weekdays 6:30–10:00 and weekends 7:30–11:00 (for a fee). Room service is available during limited hours, and the bar pours specialty beers, wine and cocktails.
