John Martin Reservoir provides uncrowded boating, waterskiing, and spectacular conditions for a wide variety of wind water sports. The mild southeastern Colorado weather provides plenty of great days throughout the year. Anglers from shore or boat catch walleye, saugeye, bass, wiper, crappie, perch, and catfish.

Many consider the park a birdwatcher's paradise with almost 400 species documented in Bent County.  Majestic Bald Eagles roost here in winter.  Threatened and endangered species like the Piping Plover and the Least Tern make the park their home for several months each year. After the birds go to sleep, the stars entertain in a dramatic display of celestial light.
