I read 'Watership Down' for the first time in high school, and the ending really stuck with me because it felt earned rather than just happy. After the final, brutal fight with General Woundwort and the Efrafans, the survivors from Hazel's warren settle into the down. Hazel becomes their respected chief, but the book makes a point that he's weary from the journey and the leadership. The last chapter has this incredibly peaceful, almost mystical tone. Hazel is visited by the spirit of the Black Rabbit of Inlé, the figure of death in their mythology, who invites him to join his Owsla. He passes away quietly, surrounded by his friends who understand it's his time. It’s not a tragic death at all—it’s presented as a dignified end for a rabbit who has done everything he set out to do. His brother Fiver, who had the visions that started their journey, is left with the thriving warren, implying the community will continue. Bigwig, the former Efrafan officer, is there as a pillar of strength. The very last image is of Kehaar the gull flying away for the last time, which always gives me a lump in my throat. It closes the loop on that unlikely friendship. The ending manages to balance the cycle of life and death perfectly; it’s somber but deeply satisfying, wrapping up Hazel’s arc with a sense of mythic completion rather than simple finality.
Some readers find it too melancholy, but I think Adams nails it. The rabbits achieve their literal and symbolic home—a safe warren on the high down—and the story acknowledges that such peace comes at a cost and has a natural endpoint. It’s an ending about legacy. The warren is secure, the stories are being passed down (like the tale of El-ahrairah), and Hazel gets a hero's send-off that feels rooted in the book's own folklore. It never sugarcoats the harsh realities of their world, even in victory.
