Like difficult terrain, obstacles can hamper movement. If an obstacle hampers movement but doesn’t completely block it , each obstructed square or obstacle between squares counts as 2 squares of movement. You must pay this cost to cross the barrier, in addition to the cost to move into the square on the other side. If you don’t have sufficient movement to cross the barrier and move into the square on the other side, you can’t cross the barrier. Some obstacles may also require a [[SRD:Skill Check|skill check]] to cross.

Flying and [[SRD:Incorporeal|incorporeal]] creatures can avoid most obstacles.

A creature with a climb speed has a +8 racial bonus on all [[Climb]] checks. The creature must make a [[Climb]] check to climb any wall or slope with a [[SRD:DC|DC]] of more than 0, but it always can choose to take 10 even if rushed or threatened while climbing. The creature climbs at the given speed while climbing. If it chooses an accelerated climb , it moves at double the given climb speed (or its base land speed, whichever is lower) and makes a single [[Climb]] check at a –5 penalty. Creatures cannot [[SRD:Full-Round Actions#Run|run]] while climbing. A creature retains its [[SRD:Dexterity|Dexterity]] bonus to [[SRD:Armor Class|Armor Class]] (if any) while climbing, and opponents get no special bonus on their attacks against a climbing creature.

A creature with a swim speed can move through water at its swim speed without making [[Swim]] checks. It has a +8 racial bonus on any [[Swim]] check to perform some special action or avoid a hazard. The creature can always can choose to take 10 on a [[Swim]] check, even if distracted or endangered. The creature can use the [[SRD:Full-Round Actions#Run|run]] action while swimming, provided it swims in a straight line.
