Nothing beats chilling out by the water while you're on vacation. Bring a picnic to Deoria Tal Lake and then hang around for a pretty sunset.
You'll have sightseeing choices galore when staying in Ukhimath. Deoria Tal Lake is an ideal place to begin here, but there are many other worthy attractions to consider. Tungnath Temple, Madmaheshwar Temple, and Madhyamaheshwar Temple are close to the body of water and will fill in your day nicely.
