Camping and Other Events
During registration, participants will have the option to reserve a camping site in the Royal Elk Meadows camping area. These sites are available if participants would like to spend the night at the venue before the swim. Up to 4 swimers will be allowed to stay at a campsite. These swimmers should be from the same group, so as to minimize potenial COVID-19 exposure pathways. Interaction between campsites will not be permitted. The costs associated with the camping site reservations are separate from the regular registration fees. Camping site reservation fees are $40 per site and are available for Friday night only. Campers will need to clean around and pack up their sites no later than 2:00PM on Saturday. During check-in, campers will be required to present proof that at least one member of each campsite intends on swimming in the Castle 5K/10K. Spectators may not reserve campsites. Spectator camping is available 90 days before the event at https://www.castlemountainrec.com/campsites. Camping will be dispersion-style camping near the parking area. There will not be designated campsites. We ask that you respect the area and the people around you, as the camping is surrounded by Colorado's beautiful Pike National Forest, which is public land. Please avoid leaving trash and do not cut down trees for firewood. Please leave the area in the same condition as you found it.
Campers should drive through the gate and follow the signs to the "Castle 5K/10K camping." At the fork in the road, take a left. After arriving, campers should go to the camping registration table before setting up camp.
Camping check-in will be from 2:00 to 7:00 on Friday.
From Denver: Take Highway 285 South to Bailey. Turn left on Wellington Lake RD (first major left at the bottom of the hill). Follow the road for approximately 5 miles and go past the main office and over the dam. Drive past the lake and up the small hill. On the right, there will be a gate. Go through the gate. At the fork in the road, take a left to go towards parking and camping. Follow the signs.
After parking, you will need to walk approximately 2/3 mile to get to the start. The walk from the parking area to the start of the swim is approximately 2/3 mile and takes 15-20 minutes. To get to the start walk back out the road you entered until you reach the fork in the road. Stay to the left (do not go back out the way you drove in) and go down the dirt road. The swim will be on the right near the bottom of the hill at the lake.
