    Blue Sky Mammoth

    Smokeless Patio Fire Pit • 30"

    The Blue Sky Mammoth 30" is a big, backyard-ready smokeless patio fire pit built for real wood fires and a larger hangout circle. Once it gets fully hot, the double-wall secondary burn cuts down smoke a lot compared to a basic open fire bowl.

    Great if…

    • You want a larger low-smoke pit for regular backyard hangs (about a 4–6+ person pit) 
    • You like dual-fuel flexibility (firewood or wood pellets) depending on the vibe and cleanup you want 
    • You want easier cleanup than most big smokeless pits (lift-out ash catch accessible from the top) 
    • You want a “set it up and leave it” patio centerpiece, not a travel pit

    Think twice if…

    • You want something you’ll move often (it’s roughly a 30" pit and around 67 lbs) 
    • You expect truly zero smoke at every moment (startup and low/ending fires can still smoke with damp wood) 
    • You want “premium brand” fit-and-finish or stainless showpiece vibes (this is more practical heavy-duty steel) 
    • You want maximum leg-level warmth without add-ons (like many smokeless designs, heat can draft upward)

    Our take…

    This is a big, backyard-first smokeless pit that’s designed to burn cleaner once it’s hot, with an easy top-access lift-out ash catch that keeps cleanup simple. You’re getting size and convenience for the money, but it’s a heavy, mostly-stationary patio piece.

    The quick, real-world stuff: cooking, warmth, space, and what it’s like to live with.

    Cooking Ready?

    Not for cookingSnack-only (s’mores, hot dogs)

    Ideal Group Size

    6–8 people (small party)4–6 people (family size)

    Heat Radius

    Comfortable within ~5 ft

    Space Needed

    Large patio lounge (10' x 10' clear space)Needs full seating circle (8–10 ft diameter)Not for small balconies or tight decks

    Worthy Mentions

    • This pit is happiest when it’s burning hot: expect some smoke during startup, then a noticeably cleaner burn once the secondary burn kicks in.
    • Dual-fuel is a real perk: wood pellets are the “easy button” for quick, consistent heat; firewood works great too, but smaller splits help it stay clean-burning.
    • The lift-out ash catch makes cleanup much less annoying, but the high-heat paint will still discolor over time and surface rust is a normal “patina” on steel pits.

    In Plain English

    The real-world take

    Short, practical notes—what matters, what doesn’t, and what to expect.

    Why we like it

    • Lift-out ash catch and grate (with handles) makes cleanup way easier than most wood pits 
    • Dual-fuel flexibility: burn firewood and/or wood pellets depending on how “easy mode” you want the night to be
    • The extended top bezel and raised burn chamber are designed to improve airflow and help the smokeless effect kick in faster 
    • It’s a true “big flame” pit for groups, not a small portable vibe pit

    Best for

    Backyards and larger patios; families and small groups who want a bigger fire with less smoke; people who care about easy ash cleanup.

    Things to know

    • It’s cleanest mid-burn; startup and end-of-burn can still smoke, especially with damp wood 
    • It’s heavy (around 85 lb), so it’s not something you’ll casually move often
    • Some retailers sell versions that include a spark screen and screen lift, and others don’t—check what’s included before you buy 
    • Give it proper clearance and use it on a non-combustible surface (don’t tuck it under overhangs)

    Other HearthTrail favorites

    If you want a smaller footprint in the same brand, look at the Blue Sky Peak (24"). If you want a more premium “accessory ecosystem” path, the Breeo X Series 24 is a common step-up for people who also want to cook over flame.
