These descriptions are based upon our experiences.  Caves, even those considered easy, are dangerous places to be.  Dont be misled into thinking that just because we call a cave easy, means it cant kick your ass.  So do your research (again) and take our opinions for what they are: biased, off-base, jaded opinions.  Click on the Cave Safely button to learn more.

Fault Caves - GPS Coordinates N39 44.592  W105 15.393
The Fault Caves are a series of fissures in the mountain with several entrances created when a fault line in the mountain started to slip.  There are no decorations here, and it’s very dry and dusty.  There’s lots of graffiti, as these are considered by many to be party caves.  The Fault Caves are located just west of Golden along Hwy 6.  Park at mile marker 270 and take the well-used trail up the mountain north of the highway.

Mallory Cave - GPS Coordinates N39 58.447  W105 17.368
Mallorys is a small sandstone shelter cave consisting of one undecorated room.  Boulder Mountain Parks closes this cave from June through October because of the nesting bats inside.  Please respect the fences to protect the bat  population.  To get there, park at NCAR just west of Boulder.  Follow the well-marked trail to the west, and follow the signs to the cave.  The hike is approximately 1.5 miles each way and gains 900 feet in elevation.  A hard-rock scramble leads up to the entrance.  Get map.

Palmer Lake Ice Cave - GPS Coordinates N39 07.026  W104 56.092
Palmer Lake Ice Cave is at least 500 feet of mostly crawlways formed under a monstrous pile of boulders. In the winter, ice has been known to block the entrance, and in spring and summer, flowing  water can make access difficult depending upon the flow level.  Starting from the town of Palmer Lake, hike west on the trail to the lower reservoir.  From the west end of the lower reservoir, the trail bends to the left and a ravine leads up to the right.  Follow the ravine a quarter mile to the entrance, which sits in the ravineGet map.

Lost Creek Caves - GPS Coordinates N /A
The Lost Creek Caves are located in Refrigerator Gulch 38 miles SW of Denver, and are inside the Lost Creek Wilderness Area.  (Read: long, exhausting hike)  They are boulder caves that were formed by the slumping of the canyon walls.  As the stream cut deeper into the canyon, the walls leaned inward towards each other.  Eventually the walls collpased and soil began to form over the top.  There are many such caves in this area, the longest having around 2500 feet of passage.   The caves are easily located on the McCurdy Mountain 7.5 minute topo map.  They can be seen as the stream disappears into the ground, hence the name Lost Creek, then reappears further down the canyon.  Most of the time you are in the water in these caves, and a wet suit is a good idea.  Do not attempt to explore these caves during spring runoff.  Go when the water levels are down.
A special word of caution here:  These caves were the site of a fatal accident in the 1980’s.  Bruce Unger, an experienced caver, slipped and fell in Goose Creek Cave, becoming lodged in a crevice.  The cold water that filled the passage soon covered him and despite the attempts by his companions to free him from the crevice, he remained stuck and perished under the icy water. 
Get this into your head good.  The underground world  can be very unforgiving and the dangers are not to be underestimated.  Bruce was a qualified, prepared caver.  A simple slip or misstep in any cave can and has led to disaster.
