Monsters & Traps for a D&D 5e Jungle Adventure

Are your adventurers lost in the jungle while looking for that lost temple? Did you send them into the jungle with a treasure map? Let us do the work for you.

My players are currently exploring a jungle island and I needed to find some monsters, beasts, NPCs and traps to throw at my players. This article provides monsters from the Dungeons & Dragons 5th Edition Monster Manual and some traps that I think fit well in a jungle setting. As I was preparing for my next session, I thought I’d share some of my favorites from the  jungle. I see a jungle as setting that can be as dangerous as the monsters that live in it with trees and vines coming to life, quicksand, spiked pits and more.


The D&D 5th Edition Monster Manual provides lists of Monsters by Environment in Appendix B. While there is a Forest Monsters list, there’s no specific list for Jungle/Tropical Rain Forest. This list contains many beasts and is a focused towards challenging lower level characters, but there are some tough monsters here too.

  • Ape Warrior

    Challenge Rating: 1 | Homebrew
    The regular ape has a CR of 1/2. For my island, I needed smart apes from a society with agriculture and metallurgy. My players have started to encounter these apes after the mysterious kidnapping of most of their ship’s crew. These apes are not quite as strong as regular apes, but they can still climb and multiattack.


    Medium humanoid (ape person), any alignment

    Armor Class 16 (Breastplate 14 + Dex Modifier)
    Hit Points  28 (4d8+8)
    Speed 30 ft., climb 30 ft.
    15 (+2) 14 (+2) 14 (+2) 10 (+0) 12 (+1) 10 (+0)
    Skills Athletics +4, Perception +3
    Passive Perception 13
    Languages any one language
    Challenge 1 (200 XP)


    • Multiattack. The ape warrior makes two fist attacks or two shortsword attacks.
    • Fist. This ape still knows how to attack with its fists. Melee Weapon Attack +4, reach 5 ft., one target. Hit: 6 (1d6+2) bludgeoning damage.
    • Shortsword. Melee Weapon Attack +4 to hit, reach 5 ft., one target. Hit: 6 (1d6 +2)
    • Javelin. Ranged Weapon Attack +4 to hit, reach 30 ft./120 ft., one target. Hit: 6 (1d6 +2)
  • Tribal Warrior

    Challenge Rating: 1/8 | Monster Manual page 350
    When encountering tribal warriors it might be fun if they don’t speak Common, creating the chance for interesting social encounters using hand signals and body language to communicate (when they are not throwing spears at your players). You could also use Commoner, Priest, Scout or any other NPCs for the base of a primitive person. You could even have your players be members of a tribe in a primitive campaign, by having them adjust their starting weapons and armor. For added fun turn them into cave people, Aztecs, cannibal halfings or ape people.

  • Snakes!

    Challenge Rating: 1/8 to 2
    Snakes come in regular and giant size and the jungle is full of them. I had a giant poisonous snake just drop out of the trees into the middle of my players. You could also use poisonous snakes to fill the bottom of a pit trap. Giant constrictor snakes are a decent challenge for starting players at at CR of 2 and a piercing Bite and bludgeoning Constrict attack which can grapple your players.

  • Dinosaurs

    Challenge Rating: 2 to 8 | Monster Manual page 79-80
    Dinosaurs are awesome and if you are looking to get a Land of the Lost type feel, a Tyrannosaurus Rex crashing through the jungle does the trick. Your group of adventurers is traveling through the jungle and finds a huge T-Rex crashes into the forest clearing bearing its massive teeth. Have Pteranodon fly over your players and have them try to figure out what it is as they chase it to a valley filled with dinosaurs. For even more prehistoric ideas check out D&D 5e Monsters for a Prehistoric Encounter.

    The Monster Manual has 5 dinosaurs you can send out for a forest encounter, but you should have a reason for the dinosaurs being there. Are you running a prehistoric campaign? Are you players exploring a lost world? Are the dinosaurs the creation of an insane magic user? Maybe dinosaurs never went extinct and raptors are bring used as mounts by halflings. If you want to go Jurassic World check out my homebrew Velociraptor and Indominus Rex monster builds.

  • Dragon, Green

    Challenge Rating: 2 to 22 | Monster Manual 93 to 96
    Green dragons are cunning, treacherous and nasty. A green dragon would be right at home in a lair located in the center of a jungle shrouded in acrid fog. They are also known for taking both living and material treasures to their lair. With four dragons to choose from you can have your adventurers battle a green dragon before they are super heroes.

  • Quipper / Swarm of Quippers

    Challenge Rating: 0 to 1 | Monster Manual pages 335 & 338
    These piranha like carnivorous fish have sharp teeth, but are not a challenge individually. If a player was to fall into a river,  a swarm of these could be a challenging or even deadly trap, especially with advantage from Blood Frenzy and a ton of damage resistances and condition immunities.

  • Giant Ape

    Challenge Rating: 7 | Monster Manual page 323
    What is a land of the lost without King Kong? Send out this huge beast for an awesome solo battle. For an encounter to remember, give your giant ape somewhere to use its climbing ability (climb 40′) and its +6 strength to grapple.

  • Lizardfolk

    Challenge Rating: 1/2 to 4 | Monster Manual pages 204-5
    These primitive reptilian humanoids are usually found lurking in the swamps and jungles. Lizardfolk can be used as dinosaur people (like Dragonborn) or they can be left as themselves to create a primitive tribe to battle. With their ability to use magic, they can provide a threat that is more than just physical. They often worship dragons, so they could worship predatory dinosaurs or a green dragon. With stats for three types of Lizardfolk, they can easily be used as the primary threat in your jungle.

  • Giant Crocodile

    Challenge Rating: 5 | Monster Manual page 324
    The giant crocodile is more stealthy than its smaller cousin and it can hide underwater for 30 minutes just waiting for a passing adventurer. With a multiattack that includes a bite (and grapple) and attack with its tail – this beast can keep a party of adventurers busy. Just a couple of these huge beasts could present a deadly challenge, especially if the crocs got the jump on the adventurers with a surprise round or if they drag a grappled foe underwater.

  • Treant

    Challenge Rating: 9 | Monster Manual page 289
    These awakened trees are most likely found in ancient and magical forests. Adventurers should be careful not to cross these guardians who can call on the forest itself to ensnare and attack enemies. You could create a tribe of massive treants made of jungle trees covered in vines.

  • Carnivorous Plant

    Challenge Rating: 2 | Homebrew Monster
    The Carnivorous Plant is a type of living foliage that look like a giant plant. Its head resembles a giant Venus Fly Trap with teeth, but is reddish-purple in color and it has 2 long, arm-like tendrils. This deadly plant remains motionless until it detects a creature within range using its Tremorsense or Blindsight.

  • Couatl

    Challenge Rating: 4 | Monster Manual page 43
    For an Aztec feeling jungle setting, try out a couatl with some pyramids, tribal warriors (bump up their stats!) and jaguars (see Panther). The name ‘couatl’ is a reference to Quetzalcoatl, an Aztec god, sometimes called ‘The Plumed Serpent’. Adventurers that encounter one of these ancient monsters will have to deal with changing shape and being bitten/constricted.

Bonus Monsters & Beasts

Here is a selection of some additional beasts and monsters that didn’t make the list above:
Ape, Awakened Tree, Boar, Baboon, Crocodile, Giant Bat, Giant Boar, Giant Fire Beetle, Giant Frog, Giant Spiders, Jaguar (use Panther stats), Panther, Shambling Mound, Swarm of Insects, Tiger, Vine Blight, Yuan-Ti.


Here is a small selection of traps that fit well in the jungle. You can create your own like a rushing river, plants and or vines attacking and more.

  • Quicksand

    I looked to Pathfinder’s Core Rulebook for some ideas on how to use quicksand.

    A patch of quicksand will usually appear solid and might even be covered with debris. An adventurer who is traveling at normal pace (not running) should be given a DC 15 Wisdom (Survival) check, which is enough to recognize the danger. A running creature will not be given a save and travel 5′-10′ into the pit (roll 1d2 x 5′). A typical quicksand pit should be around 20′ in diameter.
    Creatures in quicksand need to make a DC15 Strength (Athletics) swim check to move 5 feet (in any direction), failure results in sinking 5′ and beginning to drown. You may want to allow close fails of 4 or less to float where they are. A creature whose head falls beneath the surface of quicksand will need to succeed on a swim check to get to closer to the surface or be rescued, otherwise see drowning rules.
  • Tar Pit

    Tar pits can often be found scattered throughout the jungle or ruins. They would appear as nothing more than a shallow pond, but a DC 13 Wisdom (Survival) check is enough to recognize the danger. A tar pit functions as quicksand and ignites if brought into contact with open flame.

  • Falling Net

    See page 122 of the Dungeon Master’s Guide. A trip wire across a path can set this trap off or you could convert the trap to release from underneath and suspend your adventurers like in Return of the Jedi.

  • Poison Darts

    See page 123 of the Dungeon Master’s Guide. Poison darts could be set by ape people or tribal warriors and triggered with a trip wire versus pressure plates. This could be converted to a spear trap as well.

  • Pits

    See page 122 of the Dungeon Master’s Guide. Of the four pit types from the DMG, the Simple Pit, Hidden Pit and Spiked Pit will all fit well in the jungle. The Locking Pit would be better placed when emerging from the jungle into ancient ruins.
