DENVER (KDVR) — Calling all spider lovers: It’s almost time for thousands of male tarantulas to crawl across 433,000 acres in southeast Colorado for their mating season.

If you aren’t creeped out by that mental image, there’s still time to catch the many-legged sighting, which occurs between late August and early September.

Nexstar’s KDVR spoke with a tarantula expert for the top spots you might catch a glimpse of the “mate-gration.”

Sara Stevens, the director of animal collections at the Butterfly Pavilion, named a few places she expects to see the 5-inch spiders:

Comanche National Grassland

Your best bet is to go to the grasslands for tarantula viewing. Stevens said the grasslands are a place where there are usually higher concentrations of tarantulas. Visit La Junta recommends Highway 109 on the Comanche National Grassland.

La Junta

Stevens also recommends La Junta because it’s most associated with the tarantula trek. It even has a webpage dedicated to tarantulas. It also hosts the La Junta Tarantula Fest in Downtown La Junta, which sets up a parade, vendors, tarantula tours, and more.

The website also names a few specific spots around La Junta where you might have tarantula viewing opportunities.

Sierra Vista

About 20 miles from La Junta is Sierra Vista, which is a popular spot where people travel to check out spiders. There’s a 3.7-mile hiking trail where you can walk through the ruts of the Santa Fe Trail between Sierra Vista Overlook and Timpas Picnic Area. Be on the lookout for spiders, but don’t get too close: tarantulas can bite. While not toxic, the bite could still be painful — experts say it would be more like a bee sting.

Timpas

Visit La Junta also recommends Timpas, which is about 15 miles away from La Junta. It’s along Highway 350, which is a top driving route to scout out spiders. Tarantulas are sometimes seen crossing the highway. The website recommends going east on County Road N, south on County Road 25, east on Forest Service Road 2200, north on Highway 109, and then back to La Junta.

Vogel Canyon

Many people go to Vogel Canyon not just for the spider spotting, but because it’s a common place for hikes of all levels. They have a range of difficulty and length, which take you to the mesa top or canyon bottom.

If you can’t make it out to see the migration, there are still places to see them here (don’t worry, it’s not in the wild). The Butterfly Pavillion hosts around 500 tarantulas that you’re able to see. If you want to get even closer, they have a tarantula you can hold named Rosie. Stevens expects that over the 28 years, almost 3 million people have held her.

If you’re daring enough to seek out the spiders, Visit La Junta suggests looking around an hour before sunset in less populated areas. You’ll probably only see a maximum of 10 scurry across the prairie, said Visit La Junta.
