We booked a house with sauna, solarium and bath to have enough options even if the weather was not that good. The house was spacious and pretty complete. We did not visit the indoor pool, no opinion on that. The park restaurant was for holiday a park above average and there are some more good restaurants at walking distance. The Burg next to door was a nice walk and it is recommended to look at Eifelschleifenfor nice walking routes nearby. Also, for bikes there are enough options. A petty that this year the Kronenburgersee is not accessible for water sports due to repair work
