D&D 5e Hexcrawls & Navigation Questions for Dungeon Masters
Practical answers for running hexcrawls, pointcrawls, route choices, map scale, getting lost and navigation-focused D&D exploration.
Use this section when meaningful travel decisions come from routes, maps, hexes, landmarks, navigation procedures or uncertainty about where the party is going.
Can a hexcrawl sustain a campaign on its own instead of merely connecting dungeons?
A hexcrawl can sustain a campaign by itself when movement across the map creates decisions and consequences, rather than functioning as empty time between prepared sites. Dungeons can remain major destinations, but the campaign becomes a hexcrawl when routes, information, resources, factions, hazards, and discoveries make the space between those destinations strategically meaningful.
Give routes different costs and opportunities. A safe road may be slow and politically controlled; a marsh route may be dangerous but reveal a shortcut; a mountain pass may open only after the characters secure local help. Let discovered information change later choices, so mapping, rumors, landmarks, and failed expeditions have lasting value.
The world should also react. Factions move, settlements change, monsters relocate, and previously ignored locations become important because of what the party did elsewhere. That creates continuity without requiring every hex to contain a dungeon-sized event.
A useful test is simple: if removing travel would erase important choices, discoveries, or consequences, the hexcrawl is doing campaign work. If nothing changes except how long it takes to reach the next dungeon, it is mostly connective procedure.
How should a DM choose hex size for a nautical D&D campaign with long-distance island travel?
Choose nautical hex size from how often you want the voyage to produce a meaningful decision, not from finding the neatest mathematical divisor of ship speed. If one hex represents roughly one useful unit of travel play, the map will help pacing instead of turning every journey into dozens of empty movements.
For a campaign built around moving between islands, decide what a normal route should feel like first. Perhaps the short route takes two or three meaningful travel steps but crosses dangerous waters, while a safer route takes five or six and consumes more supplies. A third route might depend on currents, weather, or information the characters can obtain. Then choose a hex scale that makes those differences visible.
A 24-mile hex can be perfectly useful if it roughly corresponds to the cadence you want. Smaller 4- or 8-mile hexes add resolution, but that resolution is worthwhile only if position at that scale changes choices. If most small hexes contain no decision, they create bookkeeping rather than exploration.
Do not feel obliged to roll a random encounter for every hex. Use the map to track time, weather, sightings, resources, changing islands, and route commitments, then introduce events when the state of the voyage makes them meaningful. For islands that physically relocate, record both their last known location and the date of that information. Suddenly navigation itself produces uncertainty without requiring a denser grid.
The correct scale is the one that makes players understand distance, cost, and alternative routes at a glance.
What should a DM do with unkeyed hexes during overland travel?
An unkeyed hex does not need an encounter simply because the party entered it. Spend table time only when the travel changes the characters' knowledge, risks, resources, position, or choices.
If the terrain is ordinary and nothing relevant happens, summarize it. Describe the landscape, advance the travel time, apply any established resource procedure, and move to the next decision. Empty travel is allowed to be empty.
When you do add something, it does not need to become a full encounter. Weather may alter the route. Tracks can reveal nearby creatures. Smoke on the horizon can foreshadow a keyed location. A damaged bridge can create a choice between time and safety. A traveler can carry news that changes the party's priorities.
Camp scenes deserve detail only when a meaningful decision is present: where to camp, whether to light a fire, who keeps watch, what to do about a nearby threat, or whether to spend scarce resources.
Treat 'unkeyed' as a preparation label, not a fictional claim that absolutely nothing exists there. You can improvise when the situation calls for it. Just do not fill every blank hex with mandatory content. Contrast and skipped time help the genuinely important locations feel important.
How can a DM run a mapless pointcrawl where players still make meaningful route choices?
Run the pointcrawl as a graph of situations rather than a hidden map the players are expected to reconstruct. Each node should contain something already happening, and each exit should be signaled by information the characters can perceive: tracks, smoke, voices, a smell, a fleeing survivor, or a recurring landmark.
The choice should be about what the party wants to pursue, not about guessing an unlabeled direction. A battlefield aftermath might offer three leads: follow deserters before they disappear, trace a distant horn, or search the dead before scavengers arrive. Behind the screen, those choices connect to different nodes on a small graph.
Give transitions a cost so routes matter even without visible geography. Time, daylight, supplies, exposure, or progress by an enemy faction can all make “which path?” meaningful. Rumors and prior investigation can then improve decisions by revealing what a route is likely to contain rather than being mandatory for navigation.
Finally, let revisited nodes change. Patrols move, bodies are looted, rituals finish, and abandoned scenes attract new occupants. The players may never see a map, but they should feel that they are moving through one coherent area whose situations continue evolving after they leave.
How can a DM help players who are stuck in a maze without simply giving them the solution?
Do not make a stuck party repeat the same navigation failure until someone guesses correctly. Give the maze more information and more consequences instead of secretly solving it for them.
Start by adding reliable landmarks: a dripping wall, a statue facing east, a warm draft, old chalk marks, or a sound that grows louder near one region. Let careful observation reveal how those clues relate. If the characters test a sensible method—marking turns, following airflow, mapping intersections—reward it with real progress rather than another arbitrary loop.
When a navigation check fails, change the situation. They may lose time, consume supplies, reach a dangerous chamber, attract a creature, or discover a clue from the wrong side. Failure should make the maze more costly or strange, not merely reset the party to the same junction.
If they remain stuck, introduce help through the fiction: footprints from another explorer, a trapped inhabitant who knows part of the route, or evidence that one passage was recently used. The players still decide what to trust and where to go. The maze stays a challenge, but the session keeps producing choices instead of becoming an endurance test in confusion.
How densely should a DM key a large hex map if the party travels about two hexes per day?
Do not try to key all 567 hexes before play. For a first hexcrawl, prepare a dense local region around the party's likely routes and expand outward as their plans become clearer.
If the group normally travels about two hexes per day, aim for roughly one meaningful keyed discovery per travel day on routes you expect them to use. That does not mean every second hex must contain a landmark. Cluster sites around settlements, rivers, roads, passes, ruins, and objectives the players already know about, then leave wider gaps in remote wilderness. Random encounters can carry some of the texture between fixed locations.
A practical starting pass is around 40 to 60 meaningful keyed sites for a map that large, with most concentrated in the portion the party can plausibly reach during the next several sessions. Include a smaller number of off-route discoveries so exploration can reward curiosity rather than only following obvious paths.
Key relationships as well as locations. A ruin should point toward another site, a settlement should know rumors, and an abandoned camp can show where a faction moved next. After each session, develop the region the party is approaching. Density should follow actual play pressure rather than an even mathematical distribution across the whole map.
How can a DM run an OSR-style fantasy crawl through snail-mail or play-by-post correspondence?
A postal crawl works best when each exchange resolves one compact decision and leaves the next choice clearly in the player's hands. The delay between letters becomes part of the rhythm, so avoid turns that require several rounds of clarification before anything can happen.
Give every letter four pieces: the current situation, the information the character can act on, any roll or resource change that matters, and a direct prompt for the next decision. In a dungeon or wilderness crawl, keep a persistent map, time record, light supply, wounds, and other expendable resources. Those continuing facts create the sense that the expedition exists between letters.
Use procedures that tolerate asynchronous play. Instead of asking for a dozen conditional instructions, let the player state an immediate goal and perhaps one fallback: “search the shrine; if someone approaches, hide.” Resolve that fully and report the consequence in the next letter.
The format is especially good for atmosphere. Physical maps, copied inscriptions, stained notes, or letters from NPCs can become game objects rather than mere decoration. Keep the rules overhead light enough that the interesting part of opening the envelope is discovering what changed and deciding what to do next.
How should a DM run navigation when the party is lost in a huge underground cave network?
Use a small network of destinations, clues, and travel consequences rather than making the party either pass one navigation check or wander blindly until they die. The characters can be genuinely lost without the game itself becoming directionless.
Prepare three or four nearby locations as nodes and give each at least two signs that can point toward it: airflow carrying smoke, worked stone, underground water flowing toward a settlement, tracks, distant bells, fungi harvested with tools, or abandoned camps. When the party chooses a direction, reveal something concrete. A successful Survival or similar check can identify the sign correctly, shorten the route, avoid a hazard, or preserve resources. Failure should normally cost time, light, food, Hit Dice, position, or an encounter while still revealing enough information for another decision.
A random table is useful for generating complications, but it should not decide whether the adventure continues. Likewise, a full hidden hex map is worthwhile only if detailed navigation is meant to be a major part of the campaign. Otherwise it creates substantial bookkeeping for decisions that may feel arbitrary underground.
The lost state can still be a consequence of losing their guides. Let them take longer routes, encounter more danger, miss opportunities, and arrive somewhere unintended. Those consequences matter without turning one earlier decision into an inevitable slow-motion party kill.
