Visit the famous Eklingji temple complex (dedicated to Lord Shiva) for its architecture and local religious atmosphere; temples are open early morning through evening.
On the way back, stop at Nagda to see the ancient Sas-Bahu temples and old stepwell ruins — small entrance/time investment and historically interesting.
If schedule permits, take a brief final boat or walk along Lake Pichola to soak in the views before checkout. Boat timings usually daytime; confirm locally.
