The private beach and green estate are enough to fill my days at Castello del Sole without planning every outing. For next season, I would confirm the services available on my dates before booking.

Is it for you?

As a couple, I would book 2 hours in Spa Suite Onsernone for private use.

I’d ask for
Sauna, steam bath, whirlpool and terrace within 70 m².
Worth knowing
It costs CHF 350 for 2 people and CHF 100 for each extra hour; open 10am–7pm, by reservation.

  1. The estate’s rice

    At the table, I would look for the estate’s Loto rice. Dry cultivation began with experiments in the 1990s; today the harvest yields risotto rice alongside other produce from the fields and gardens.

  2. A week booked together

    For 17–24 May 2027, prices start at CHF 705 per night for 2 adults when all 7 nights are booked together. Room category, meals and taxes are unspecified; I would ask for the complete quote before confirming.

  3. Children beside the lake

    Between the pool, playground and beach, I would be clear about who is watching the children. The hotel’s conditions place responsibility for their safety on parents or the appointed adult throughout the resort, including the raft area giving access to the lake.

How we choose the hotels

The 5 things that matter, as guests tell them

What do Castello del Sole’s guests say? They write it in their reviews, even those who only came for a drink or dinner: we read every one and tell the 5 things that matter, from the location to the bill.

  1. Location

    Every guest who mentions it is happy with it. Guests describe a green setting, with the lake and park central to their stay.

  2. Room

    One guest values the Deluxe Junior Suite; another finds the Superior bathroom small.

  3. Staff and service

    Nearly every guest who mentions it is happy with it. One guest describes the welcome for three generations; another describes a tense atmosphere, including an impersonal atmosphere in the Spa.

  4. Breakfast

    Guests value breakfast and the regional produce.

  5. Price

    One guest finds a five-night stay worthwhile; another finds the price high, including the SUP charge.

66 guests said so on Google, from 1 November 2024 to 19 October 2026. Includes meals and visits without an overnight stay. The other hotels are assessed on the same 5 themes. The score is the average of what they say, from 0 if they speak of it very badly to 10 if they speak of it very well. Where only a few mention something, the score stays close to the guide’s average: a handful of voices does not make a reputation.
