Klopp Lake Loop and Mount Trashmore

There is a 0.88 mile gravel trail with flat terrain that loops around Klopp Lake. This loop is most easily accessible from parking lot E. A 0.16 mile portion of this trail connects to another 0.56 mile loop that circles Mount Trashmore. Mount Trashmore is an old dump site which was sealed and covered with the dirt from the making of the Kloop Lake. Mount Trashmore is the sight of much restoration activity, reintroducing native plants and trees. Don't be deceived by the name though it is much more of a mound than a mountain with little to no inclination. Klopp Lake is an ideal location for birding.

There are benches for resting and enjoying the Arcata Marsh and Wildlife Sanctuary, covered buildings are also available for bird enthusiasts. As shown in Figure 4 the Klopp Lake loop is a flat walk with a large portion of the trail traveling along a man-made dike between Klopp Lake and the Arcata Bay. Be prepared for a wind chill.

Oxidation Pond Loop

This is a 0.87 mile gravel road (you may encounter city vehicles) with flat terrain that loops around the Arcata Wastewater Treatment Plant's oxidation pond. This loop is most easily accessed from parking lot A. This trail is a 2.09 miles loop when including the dirt trails that lead to the oxidation pond loop. This is an informative, but less scenic walk and there are no benches to rest on as shown in Figure 5. This trail is recommended for joggers, bicyclists, and people interested in the Arcata Wastewater Treatment Plant.

When walking take the first left before reaching the Arcata Marsh Interpretive Center, travel down a 0.18 mile dirt trail, when you reach the end take another left. You will travel down another dirt trail 0.43 miles passing by the outer fence of the Arcata Wastewater Treatment Plant. You will first pass the plants digesters, followed by the sludge beds, and then you will pass by an area full of spare parts until you come to the compost piles and the treatment wetlands.
