First Advent Sunday Lake Tour

It’s the first advent Sunday and we want to go for a walk. Nala doesn’t know where we planned to go, yet, so it’s a surprise for her and she loves to explore her surroundings!

Normal Sudoku rules apply: Place the digits 1-9 in every row, column and box exactly once each.

Digits in a dashed cage must sum to the value in the top left corner of the cage. Digits may not repeat within their own cage.

Lake Tour Path: Help Nala find the path around the lake by following these rules: The path must be orthogonally connected and visit all cells of all cages. The path forms a loop (ie it has no start or end points). The path can touch itself diagonally, however it is not allowed to touch orthogonally (ie no cell on the path can share edges with more than two other cells on the path). Digits along the path differ by AT MOST 2.

Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all possible dots are given. (There is no negative constraint.)

Additionally the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
