Out on the eastern Colorado plains, far from the mountain crowds, the land runs flat, trees get scarce, and then a huge reservoir appears out of nowhere. Anglers chase crappie there, campers park their rigs beside the water, and early risers claim spots on top of a dam to watch the sun come up over the high plains desert.
Swans and geese take over a small lake in winter, while prairie dogs pop up near the campsites. Keep reading to find out where this place is, how to camp and fish there, and the handy tricks that make a visit smoother.
A Reservoir Hiding in Plain Sight
Eastern Colorado does not usually land on the cover of travel magazines, and that is part of the charm here.
John Martin Reservoir State Park sits at 30703 Co Rd 24, Hasty, CO 81044, in the southeastern part of the state. Hasty is a small town, and the park is a bit secluded, so the reservoir often feels like a private discovery.
The park wraps around a large reservoir held back by a dam, with a smaller body of water called Hasty Lake tucked below it. Fishing, hiking, camping, boating and wildlife viewing all share the space.
It is known as a tranquil spot for wildlife, with hundreds of bird species recorded on the grounds.
Travelers crossing the state often stumble onto it by accident while hunting for a place to stop for the night. Plenty of them leave already planning a return trip, and the reasons stack up quickly once the tour begins.
The Dam Worth Driving Across
Most parks save their best view for the end of a long hike. Here, the showstopper is a short drive away.
The dam that creates the reservoir is open to cross by car, and it offers a wide look over the water on one side and the plains on the other. It is one of the most talked-about features of the park, and for good reason.
Early mornings are prime time. The sunrise from the dam is a favorite moment for campers, and sunsets earn nearly equal love.
With few trees and almost nothing blocking the horizon, the sky gets a full-width stage. Photographers should plan to arrive before first light instead of right on time.
The dam also works as a handy landmark. The Hasty Campground and its small lake sit below it, while the Point Campground and the reservoir shoreline spread out above.
Crossing it once is fun, but crossing it at dawn is the real move.
Santa Fe Trail Stories and Sandstone Cliffs
Long before RVs and boat trailers arrived, wagons rolled through this part of Colorado.
The park lies along the historic Santa Fe Trail, which makes it a natural stop for anyone tracing that famous route across the plains. A hike around the area or a night of camping fits nicely into a trail-themed road trip.
The visitor center adds context with a mini museum, a smart first stop before heading out to the shoreline. The office staff are known for being friendly and helpful with questions.
The landscape tells part of the story too. Small sandstone cliffs line sections of the shore, and the shoreline has interesting twists worth exploring on foot.
Taking it slow pays off here. The cliffs, the curving shore and the wide plains reward anyone willing to wander a bit.
History buffs and casual wanderers alike can get a lot out of a short, unhurried loop through this corner of the state.
Crappie, Boat Ramps and a Little Patience
Anglers, get the tackle boxes ready, because the fishing here has a loyal following.
The reservoir holds lots of species to try for, and crappie come up again and again as a favorite target. Many people bring boats, and two boat ramps make launching easier on the big water.
Bait rules and species details can change, so the Colorado Parks and Wildlife website is the best place to check before casting. That quick step saves a lot of guesswork at the shoreline.
A fair warning keeps expectations honest. Fishing from shore can be tricky on such a large reservoir, and some anglers find the action slow.
Water levels also shift, which can affect how many fish stay in Hasty Lake below the dam.
Patience is the best lure. Early mornings tend to be calmer and less crowded, which helps.
Anyone who lands a crappie before breakfast also gets that famous sunrise as a bonus.
Hasty Lake and the Little Swim Beach
Not every body of water here needs a map to find.
Hasty Lake is the smaller companion below the dam, and it offers easier access than the big reservoir. The campground sits right beside it, with some sites close enough for lake views from the picnic table.
There is a catch, though. Reeds surround much of the lake, so getting into the water usually means driving to the far side of the campground to reach the access point.
Once there, mornings before the rush are especially calm. Blue dragonflies swarm in season, and turtles and ducks show up for anyone paying attention.
For swimming, the park has a swim beach. It is on the small side given all the water around, so arriving early on busy days helps.
Families who want a simple water day without launching a boat will find these two spots a good fit. A cooler, a towel and an early start cover most of the planning.
Swans, Prairie Dogs and a Coyote or Two
Birders tend to lose track of time here, and it is easy to see why.
Hundreds of bird species have been recorded in the park, and waterfowl gather in plain view along the reservoir. In January, Hasty Lake fills with so many geese and swans that it becomes a sight all its own.
Migrating geese keep things lively in their seasons. Binoculars are worth packing any time of year.
Land animals join the lineup too. Prairie dogs live near the campground above the dam, and coyotes are spotted around the area.
Deer roam the grounds as well, although they have a reputation for staying out of sight. Plenty of signs show they pass through, even if a sighting takes luck.
Bugs are usually not a big problem, which makes dusk wildlife watching more pleasant.
One small quirk is the Russian olive trees, which some nature lovers wish were not there. Even so, the wildlife roster here is tough to top on the plains.
Shade or Views: Picking a Campground
Choosing a campsite here comes down to one big question: shade or views.
The Hasty Campground sits below the dam near Hasty Lake. It offers electric and water sites, green grass and many large shade trees, plus sites that are big, level and well spaced.
Here is a pro tip. Sites 1 through 29 have almost no shade, while the other side of the loop is covered in trees.
The Point Campground takes a different approach. It overlooks the reservoir with excellent sunrise and sunset views, but it has no trees and only vault toilets.
A canopy or umbrella is a must at the Point in summer. Some sites across the park have metal canopies over the tables, though most do not.
Crowds rarely feel heavy. Many stays happen with only a fraction of sites filled, and even a busy holiday weekend can leave empty sites nearby, so elbow room comes standard.
Quarters, Showers and Campground Comforts
Keep a few quarters handy, because this park has one quirk people love to talk about.
Showers at the Hasty Campground are coin-operated. At last report, 50 cents buys three minutes and 75 cents buys four and a half minutes, which makes for speedy routines.
That fee supports a well-kept setup. A laundry room with reasonably priced machines, clean restrooms and water spigots around the campground make longer stays easy.
RV travelers get a dump station nearby, and dumpsters sit at the campground exit. Electric hookups are dependable, which helps during hot afternoons.
Dog owners will appreciate the grass at the Hasty sites, free of sticker burrs.
Cleanliness usually earns strong marks, though restroom conditions can vary from day to day. A campground host often makes the rounds with a friendly wave, and rangers patrol regularly.
Nothing fancy, just the basics done well, and that is exactly the appeal.
High Plains Weather With Opinions
The high plains desert does not do subtle weather.
Summer sun is intense, especially at campsites without trees, so shade gear and plenty of water are smart packing choices. Mid-August can bring warm days followed by cool nights.
Storms can change course fast. Campers have been caught off guard by sudden downpours and hail that rolled in with little warning.
Wind is the other big factor. Sites around the reservoir get extremely gusty when a storm system passes, and tents can take a beating.
Tent campers should also expect rocky ground in places. Sturdy stakes and a solid tent make a real difference.
Checking the forecast before arrival and keeping an eye on the sky during the stay helps a lot. Having a plan to move into a vehicle during a big storm is wise.
With a little preparation, the weather becomes part of the adventure instead of the whole story.
Hours, Day Passes and the Final Verdict
Timing a trip is simple, since the park opens at 5 AM and closes at 10 PM every day of the week.
That early opening is great news for sunrise fans. A day pass is available for those not camping, and plenty of guests call it money well spent.
From the Denver metro area, expect roughly a three-hour drive. It works well as a long weekend getaway or as a stop for road trippers crossing the state.
The hiking trail could use better markings, so grab a map or ask at the office before starting. Current fees, camping reservations and fishing details live on the Colorado Parks and Wildlife website.
So is it worth the trip? For anyone after wide skies, easy camping and a shot at crappie, the answer leans toward yes.
Nothing here is flashy. Just a dam, a lake, a lot of birds and sunrises that make the early alarm feel like a fair trade.
