Adventurers ages 62 and over should get a $10 lifetime pass from the National Park Service before the price climbs to $80 on Aug. 28.
Last December, Congress passed legislation that increased the price by 700 percent, making the senior pass cost equal to that of the annual "America the Beautiful" pass for the public.
The legislation established an annual senior pass for $20 for those on fixed incomes. After four annual passes have been purchased, seniors can trade them in for the lifetime pass. Senior passes purchased before the August increase will remain valid.
Passes can be purchased at any National Park Service facility, such as Florissant Fossil Beds National Monument, 15807 Teller County Road 1. Or buy a pass online at https://store.usgs.gov/senior-pass.
People without a pass can take advantage of free NPS days. This year, entrance fees will be waived at all national parks on Aug. 25, Sept. 30 and Nov. 11-12, Veterans Day weekend.
