A gem of north Boulder, Wonderland Lake is a great place to fish with kids. This site can be accessed from all bus lines that run along north Broadway, such as the SKIP, and is located along a bike path. Use of boats or floatation devices, and wading into the water, are not allowed. Visit the Fishing page for more information about fishing opportunities and regulations.

Ice on ponds and lakes

You can help to keep you and your pets safe by keeping them off OSMP's icy lakes. Many times, pets that fall into icy waters will be able to get out or self-rescue without assistance.

If it happens to you while visiting OSMP and your pet is unable to get out of the water, stay off the ice! Call 911 and Boulder Fire-Rescue will respond and rescue your pet!

Also, all dogs must be on a hand-held leash at all times in this area, which helps keep them safe.

Horse Regulations

Allowed on most trails. Off-trail riding is discouraged to protect rare plants and wildlife habitat. Learn more about riding your horse on OSMP.


Fishing is popular here and is allowed from the dam and peninsula only. State fishing regulations apply. Birds of prey are common in this area, mule deer and coyote are also frequently sighted as well as waterfowl on the lake. Mountain lions frequent the hogback ridges in this area.
