Oxbox Park has varied terrain that is excellent for beginners and intermediates.
This beginner/intermediate trail has a little bit of something for everyone. Views of the Sandy River, roots, sand, wood chips, hay, gravel, more sand, horse manure, stones, and one incredible hill climb. Added bonuses are all the trails are very well maintained (little if any overgrowth) and few people (if any) will be found hiking or mountain biking the trails (they are all at Powell Butte). The ride up to Alder Ridge/Elk Meadow is quite a feat and anyone who can make it without stopping is indeed ready for the next level. The mile or so ride around the meadow offers some breathtaking views of the river/valley below. The rain brings out tons of snails on the meadow trail. The snails, mud, and spider webs will probably make you think twice before riding it during the rainy season. Do watch out for the sand-especially when roots are about. One wrong move and you'll probably end up doing a face plant.
How to get there:
The most scenic drive is to take Exit 18 off I-84. Head south on Southeast Crown Point Highway. Several miles down the road will be the Stark Street Bridge. Turn right on Stark Street Bridge and follow the road several more miles to Troutdale Road. Turn left on Troutdale and follow the OXBOW park (green) signs. Troutdale Road intersects SE Division at a fork in the road. Make sure you veer left. After a stop sign you should be heading EAST on SE Division. Continue on down the road until you reach a large "Oxbow Park" sign. Turn left and follow the road to the parks entrance. After paying ($5 per car) and perhaps getting a map head 2 miles down the road and park at Group Picnic Area A. The bike trail starts on the North side of a large field. (See map).
